Industry Praises HACCP
Roundtable
Meeting of Minds Clears a Path for Food
Processors
- Each month several key managers at food
processing plants around Arkansas take a day away from their
offices, drive to Fayetteville and gather in an executive
conference room with a view overlooking the Ozark Mountains,
Razorback Stadium and the new freeway to Fort Smith. Lunch is
served to the group and they talk among themselves for a few
hours.
-
- This gathering of competitive business
executives is the scene of information exchanges that they hope
will help each other. But no secret in-house information is
traded. No one shares anything that would interest an antitrust
lawyer. To the contrary, the executives even invite government
officials into the room with them before the day is
over.
-
- They gather to fine tune and improve their
compliance with federal food safety regulations that govern
meat and poultry processors. They call themselves the HACCP
Roundtable (HACCP is the acronym for Hazard Analysis and
Critical Control Points, the science-based system by which
plants examine key steps in their processing procedures as
places to prevent, reduce or eliminate possible contamination
hazards).
-
- They visit the University of Arkansas
campus each month, where the Center of Excellence for Poultry
Science hosts them, moderated by Frank Jones, an Extension
section leader at the poultry center. Chris Wagoner, the HACCP
coordinator for the Townsend poultry processing plant in
Batesville, has been making the trip for a year and a half and
has found benefits he hadn't expected.
-
- "One of the things that has happened is
that the relationship between the plants and the U.S.
Department of Agriculture has improved," Wagoner said. "Instead
of trying to get by with something, it's more of a focus on
what is the right thing to do. Ten years ago it was what you
might get away with. Instead of USDA having a 'gotcha'
mentality, it's 'what can we do to help you?'."
-
- Wagoner works for a plant that employs 700
people, which makes it a large plant by USDA's classification
standards. Plants of 500 or more employees became subject to
USDA rules governing HACCP inspection in January 1998. That
means they had to have detailed plans on file and approved by
USDA that showed how the plant would implement scientific
procedures at appropriate steps to control
contamination.
-
- Plants classified as small &emdash; from 10
to 500 employees &emdash; became subject to HACCP inspection
rules in January 1999. The last group &emdash; classified as
very small plants, with fewer than 10 employees &emdash; will
come under the new rules in January 2000.
-
- Plants regulated by USDA must implement
HACCP plans and meet food safety performance standards. The
government requires that they run tests to confirm that the
standards are met. The USDA's on-site inspectors at each plant
oversee the process. All plants are also required to have
standard operating procedures in place that describe their
daily routine to ensure sanitation. USDA verifies each plant's
procedures. Plants that fail to correct problems can lose their
marks of inspection, which can shut down their operations until
corrections are made.
-
- Because the burden is largely on the plant
personnel to carry through with the inspections of their own
procedures to insure food safety, USDA inspectors examine their
paperwork to verify that they are doing what they proposed.
HACCP records maintained by each plant are required to show
records of microbial testing by the plant for E. coli bacteria
and by USDA for Salmonella. USDA says these tests are designed
to provide data that show if the products are meeting its
performance standards.
-
- The plants represented at the HACCP
Roundtable in Fayetteville are usually from the top two
categories in size. John Marcy, an Extension food scientist at
the U of A, noted that very small plants don't have enough
personnel for managers to break away for distant
meetings.
-
- "Usually these plants have one management
person and five or six employees. They can't shut down for a
day," Marcy said.
-
- Although the personnel from very small
plants are unable to attend training sessions such as those in
Fayetteville, their counterparts in larger plants sometimes
cover for them because it's in their interest to do so. The
Cargill Foods Honeysuckle White plant in Springdale has helped
some smaller plants establish the frameworks of their HACCP
plans, recently for a very small plant that must have its plan
ready to go by January.
-
- "There are some small plants that we do
business with," explained Bob Galbraith, technical affairs
manager for the Cargill plant in Springdale. "I think a lot of
other big companies have done the same thing to protect our
interests. We can't afford to have our suppliers have
problems."
-
- Those who do attend the university's
three-day HACCP training workshops &emdash; the university
holds three a year and attracts about 35 participants at each
one &emdash; come away with more than just lectures. The
participants divide into small groups and actually develop the
model of a HACCP plan for a hypothetical plant.
-
- "They go through this type of exercise and
get instructions," Marcy said. "Part of doing a HACCP plan is
learning how to defend it and think along those
terms."
-
- Large companies such as Tyson Foods of
Springdale began processing under HACCP procedures long before
the government mandated it, but even experience and plentiful
resources don't provide automatic answers to new
questions.
-
- "The HACCP Roundtable has been beneficial
for the industry and the USDA," said Ellis Brunton, Tyson's
vice president for research and quality assurance. "A lot of us
in industry have been hoping for an educational and interactive
process in HACCP in which both industry and USDA participated.
The university has been a good conduit on this."
-
- The presence of USDA representatives at the
sessions enables the industry personnel to discuss the
interpretation of regulations that may be unclear to those who
must apply them. Galbraith finds the dialogue with USDA
beneficial to both ends of the conversation.
-
- "The USDA understands the issues that we
have," Galbraith said. "We understand their concerns. We try to
work through the gray areas. For example, what's a food quality
issue versus a food safety issue?"
-
- The industry people find it makes just as
much sense to talk to each other as it does to the government
officials. Despite their competitiveness, they view food safety
as common ground.
-
- "Most of the companies that I've dealt with
feel it's beneficial for them to send people to a non-company
environment when it comes to food safety because that's not
proprietary," Marcy said. "That's not a marketing advantage.
Everyone rises and falls with that tide. No one comes out
unscathed if there's a problem. Everyone gets
hurt."
There Is No Risk-Free
Lunch
- To scientists and food industry executives,
the phrase "food safety" generally refers to the process of
making the food supply as safe as possible. That falls
somewhere short of guaranteed perfection and they'll tell you
that's because there are no iron-clad 100 percent fail-safe
methods to assure that every last square centimeter of food
coming out of a processing plant has escaped all possible
contamination.
-
- The mission statement of the U.S.
Department of Agriculture Food Safety and Inspection Service
(FSIS) doesn't hedge on the issue. It declares that the agency
is responsible "for ensuring that the nation's commercial
supply of meat, poultry and egg products is safe, wholesome and
correctly labeled and packaged."
-
- The government can inspect food for safety
but it can't guarantee the safety of all meat and poultry
regardless of any mission statement, says John Marcy, a
University of Arkansas Extension food scientist.
-
- In numerous other official documents, FSIS
speaks of reducing contamination, controlling risk, assessing
risk and other concepts that acknowledge the presence of risk .
So some interest rose last spring when the agency offered for
consideration a concept paper that discussed the idea of
"risk-free food."
-
- The concept of "risk-free" food is best
left as an unstated goal and not a vision for FSIS, according
to James H. Denton, director of the U of A Center of Excellence
for Poultry Science. "The barriers to meeting the vision can be
reduced to one simple obstacle," Denton said in a letter to
FSIS: "Human behavior."
-
- Denton serves on the Food Safety Consortium
Steering Committee and as a member of the National Advisory
Committee for Meat and Poultry Inspection. He points out that
the overall objective of food safety efforts is to reduce the
risk of foodborne illness. Systems such as Hazard Analysis and
Critical Control Points (HACCP) production and processing
procedures, education of workers in food service and retail
businesses and education of consumers on safe practices in the
home are designed toward that end.
-
- But promotion of the concept of "risk-free
food" as a vision for FSIS is irresponsible, Denton says,
"because in the mind of the consumer it becomes an implied
outcome." The concept results in expectations doomed to
failure. "When the system fails, as it inevitably will, the
validity, reputation and future of FSIS will be brought into
question."
-
- Denton maintains that under a risk-free
mandate, the food industry would be expected to meet standards
that are not scientifically achievable. He finds that
implementing sound food handling practices is the best
available way to manage the inherent risks of processing and
preparing food.
-
- "The food pathogens we are attempting to
manage are ubiquitous and therefore must be managed at the
point where reduction of risk is most efficient," Denton says.
"The concept of risk free is not scientifically supported for
food or any other life activity."
-
- Human error can upset any well-laid plans
for risk-free food. Denton cites potential examples of
producers mistakenly engaging in unsafe production practices or
food-service workers and consumers making errors in handling
food.
-
- "As long as humans are involved in the
preparation of the foods we eat, mistakes will occur," Denton
says. "As long as this is the case, the concept of risk-free
food is just that: a very academic concept."
Packaging Methods Make a
Difference for Irradiated Sausage
-
- Although irradiated meat products aren't
currently being marketed by the food industry, researchers are
examining the effects of irradiation on qualities such as
aroma.
-
- At Iowa State University, researchers for
the Food Safety Consortium looked at irradiation's effects on
cooked pork sausage to find out what would happen in different
types of packaging. The study found that irradiating the cooked
pork sausage in aerobic packaging may result in some of the
meaty aroma being diminished. The resulting odor was described
by a sensory testing panel members as being like wet wool or
wet hair.
-
- The use of vacuum packaging, however, may
protect against the development of off-odors in the irradiated
sausages.
-
- The study did not address whether the
changes in aroma would be noticed by consumers or whether the
acceptability of the product would be affected, said Dong Ahn,
an ISU assistant professor of animal science.
-
- "At this point our research is not going
into how we can prevent or manipulate those types of
processes," Ahn said. "We are examining is how it's going to
happen and where it's coming from. The next stage is how we can
prevent that."
-
- Odors can develop in cooked meats through a
process called lipid oxidation. Irradiation generates atoms
that accelerate the oxidation process and the odors described
as similar to wet hair. Irradiation also creates volatiles,
molecules which are responsible for off-odors. In the research
project, irradiated sausages produced more volatiles than
non-irradiated sausages, except for those irradiated sausages
stored for at least eight days.
-
- Cooked meat is more susceptible to
oxidative change than raw meat. "The cooking process destroys
the structure of the muscle fibers," Ahn said, enabling air and
oxidative molecules to interact and produce the
odors.
-
- The levels of fatty acids used in cooked
meats can produce different levels of odors from lipid
oxidation. Ahn noted that could mean processors would have a
way to alter their methods to minimize the effect on
irradiation-induced odors. A future phase of research will
determine how to prevent undesirable qualities that might cause
consumers to turn away from irradiated meat.
-
- With packaging apparently making a
difference in the aroma, it would appear that vacuum packaging
might be preferred as a way of preventing the off-odors. But
then color becomes the next factor to consider.
-
- The use of vacuum packaging on irradiated
cooked sausages causes the color to change to a more reddish
and pinkish tone, Ahn said. Consumers generally like to see a
color other than brown in their raw meats, but in cooked meat
the situation is different.
-
- "In the cooked meat we used, we did not add
any type of curing agents to make the product pink as in
sausages or hams. Therefore, the pinkish color would not be
desirable to consumers," Ahn said. The next step would then be
to educate consumers that a pink color doesn't mean that the
cooked meat is of a bad quality.

Report From the
Coordinator
By Charles J. Scifres
- As this issue of the newsletter goes to
press we are preparing for the annual meeting of the Food
Safety Consortium. The events of that meeting will be covered
in the next edition and there should be plenty to discuss. This
is the 10th anniversary meeting of the FSC, which makes the
occasion one for reviewing accomplishments and contemplating
the future.
-
- Issues in food safety are now a frequent
topic of discussion in the public arena. Much of that
discussion has been generated by the work of FSC personnel. For
example, the emerging national debate over the concept of
risk-free food promises to be a lively one, prompted in part by
the commentary of the FSC's James Denton and John Marcy, both
of the University of Arkansas. Their remarks on the topic are
covered elsewhere in this issue and they are making a necessary
contribution to the public's consciousness of the
subject.
-
- The topic of irradiation seems to be always
renewing itself. The latest word is that Tyson Foods, the
world's largest poultry producer, is planning to irradiate
selected items and test market them next year. That's a prime
example of the progress being made with this technology.
Numerous researchers within and beyond the FSC are responsible
for the developing confidence in irradiation, but one of the
foremost is Dennis Olson of Iowa State University. His
expertise is sought by industry, government and academic
centers as the future of the process continues to look
brighter.
-
- Attention to microbiological research is
one of the linchpins of the FSC's efforts. At Kansas State
University, Daniel Fung has gained worldwide recognition for
his work in rapid methods in microbiology. This year he has
again stirred interest in food safety with his findings on the
role of spices in fighting pathogenic bacteria. Fung's work in
that area is also profiled in this newsletter.
-
- A major national development in food safety
was revealed recently by FSC personnel at the University of
Arkansas for Medical Sciences. UAMS and a new company, Safe
Foods Corp., have teamed up to facilitate the regulatory
approval for Cecure, a food processing treatment resulting from
discoveries at UAMS. Cecure kills pathogens on food and
prevents recontamination. The story of Cecure is also explained
in this newsletter.
-
- Responding to the public's needs is the
ultimate purpose for the FSC's existence. Over the past 10
years some of the specific food safety issues before the
scientific community have changed, but the focus remains the
same: we are dedicated to producing research that enables our
stakeholders to provide the nation the safest possible food
supply.
In Meat Safety, One
Treatment Is Better Than Three
- Meat processors --- particularly those who
operate small plants --- and consumers may benefit from a
low-cost method for killing pathogenic bacteria. A research
team at Kansas State University took three separate methods of
decontaminating meat, combined them into one treatment and
found that it was effective.
-
- The finding is significant for small
processing plants because they generally cannot afford to
install the new steam pasteurization equipment that reduces
surface contamination on meat. But combining the simpler
procedures of exposing the meat to lactic acid, hot water and
microwave treatments is a cost effective alternative and
practical for them.
-
- Daniel Fung, a Food Safety Consortium
researcher at KSU, explained that the process is among the
final hurdles for the meat to clear before it reaches the
consumer.
-
- "We take the meat that has already been
cut, dip it in hot 2 percent lactic acid at 80 degrees C for a
few seconds, then we vacuum package the meat. Then it goes
through the microwave. The vacuum packaged meat will not be
opened until it gets to the consumer."
-
- An added benefit of the process is that the
meat maintains its red color during the process and gets a few
more days of shelf life after undergoing the treatments,
although Fung noted that detailed research into that aspect
hasn't been conducted yet.
-
- "We have a defined time, temperature of
treatment and vacuum package for the meat that enables it to
keep its color," Fung said. Meat subjected to steam treatments
can change color if too much steam is used. Fung said the
formula generally consists of the lactic acid, 15 seconds of
hot water at 70 degrees C and five seconds of
microwave.
-
- "When you zap it a little bit with the
microwave it will kill the organisms on the surface," Fung
said. "We don't want to cook the meat, so we are looking for
the right combination of time, temperature and how many seconds
of microwave so that the meat will not change
color."
-
- Before the KSU study, scientists knew that
each of the three treatments of lactic acid, hot water and
microwave were effective in reducing microorganisms from the
surface of meat. But no studies had been done to evaluate the
three treatments when used in conjunction with each other.
-
- More work remains to be done to determine
the effects of exposing the meat to longer microwave treatments
of seven and 10 seconds and of increasing the temperature of
the lactic acid solution to 75 and 85 degrees C. Longer
exposure and higher temperatures could kill more microorganisms
but would carry the risk of diminishing the red color.
-
- "Heat will definitely change the color so
we try to monitor at what limit we should set it," Fung said.
-
- In the preliminary study, small strips of
meat were used and now larger cuts (1- to 5-pound units) are
being investigated.
Study: Cinnamon Kills E.
coli in Apple Juice
- Cinnamon is giving the spice rack a good
name again.
-
- Kansas State University researchers say
that that adding ground cinnamon to apple cider can kill high
levels of E. coli O157:H7, a potentially deadly bacteria
sometimes found in unpasteurized apple juice.
-
- The findings add to a similar study
released a year ago by the same group. The earlier study
indicated five "killer" spices &emdash; including cinnamon
&emdash; were effective in eliminating E. coli O157:H7 in
uncooked ground beef.
-
- While last year's study didn't create a
demand for cinnamon burgers, this year's report certainly has
relevance for those who drink apple juice and possibly for
those who eat applesauce.
-
- "Cinnamon may be used during production of
these products," said Erdogan Ceylan, a KSU research assistant
who conducted the experiments. "Or, consumers could add
cinnamon to the final product in their own homes."
-
- Ceylan and Daniel Fung, the KSU Food Safety
Consortium investigator who guided both studies, presented
their findings July 27 in Chicago during the annual meeting of
the Institute of Food Technologists.
-
- This year's IFT meeting was the second
straight in which the KSU research group revealed findings on
"killer" spices. Last year in Atlanta, they reported that
garlic, clove, cinnamon, oregano and sage made ground beef
safer.
-
- "We're trying to control E. coli in almost
all food products," Ceylan said. "We're expecting results in
the near future on other studies that we're
conducting."
-
- In the apple juice study, Ceylan added
approximately 1 million E. coli bacteria cells to one
milliliter of pasteurized apple juice. The high E. coli count
&emdash; a number so high that it would be considered uncommon
for consumer food products &emdash; was used for experimental
purposes only.
-
- Then he added very small amounts of
cinnamon. Even at 0.1 percent (or 1 part cinnamon to 1,000
parts apple juice), the researchers were able to kill 90
percent of the E. coli bacteria. At higher levels,the killing
effect increased with the amount of cinnamon added.
-
- "At 0.3 percent," Ceylan said, "cinnamon
kills all of the E. coli bacteria."
-
- The KSU researchers haven't been able to
tie down exact measurements for adding cinnamon, but at 0.3
percent, a little over 1 teaspoon of cinnamon should be added
to a 64-ounce bottle of apple juice.
-
- "The idea is to control E. coli with
natural resources," Ceylan said. "We can do it with chemicals,
but we think this is a better way."
-
- One other key finding in this study relates
to apple juice left on the kitchen counter.
-
- E. coli grows especially well at room
temperature. Consumers who fear they've left apple juice out of
the refrigerator too long can treat the juice by adding
cinnamon, then re-refrigerating. Or, they can boil the apple
juice prior to serving.
-
- "Normally, buying pasteurized apple juice
and keeping it refrigerated is the best choice for consumers,"
Ceylan said. "Adding cinnamon to apple juice, whether it is
pasteurized or not, gives even more protection."
-
- Ceylan cautioned that adding cinnamon does
not guarantee 100 percent protection in apple juice. "It just
helps to reduce the risk," he said.
-
-
Irradiation and Other
Treatments Work Well Together for Ground Beef
-
- Irradiation of ground beef --- a process
already found to be effective in killing microbiological
contamination in meat --- also results in a product that
doesn't lose the qualities that consumers want. A Food Safety
Consortium study showed that ground beef maintained its flavor,
aroma, color and texture after it went through high-beam
electron irradiation.
-
- "We looked at a very specialized type of
irradiation that relies on technology that was developed at
Sandia Laboratories in Albuquerque," said James Marsden, an FSC
researcher at Kansas State University. "We wanted to evaluate
this highly specialized form of irradiation and determine if it
was valuable in minimizing the chemical changes in a
product."
-
- The KSU researchers determined that because
product quality was maintained after irradiation, ground beef
processing would be most effective if it employed combinations
of irradiation and other food safety methods such as steam
pasteurization.
-
- Irradiation would be the final step in such
an integrated process, Marsden said. "The ideal situation would
be that you would have other control points in the process so
that you come to the final step with the lowest possible level
of contamination. That allows you to use low doses of
irradiation to control the low levels of pathogenic bacteria
that might be present."
-
- The new irradiation process does not result
in any loss of vitamins in the meat. Marsden noted that earlier
research had found that other forms of irradiation sometimes
caused a reduction in Vitamin B-1. "That can be a big issue for
pork because pork is a big source of Vitamin B-1 in the diet,"
he said.
-
- The new process relies on a different
technology that prevents chemical reactions from occurring that
would cause vitamin loss. "So we have flavor typical of what
you'd get in the product and we didn't get any vitamin
loss."
-
- The tests on the ground beef patties were
performed by panelists with extensive experience in testing
meat products who had been trained in analyzing flavor, texture
and aroma. Irradiation was found to have no adverse effect on
the ground beef's juiciness, tenderness and flavor.
-
- Studies from several years ago showed that
some plastic packaging materials would create intense off-odors
when ground beef was irradiated. Since then, advances in
packaging materials and technology have resulted in more
acceptable irradiated meat products, the KSU team
said.
-
- Irradiating the patties also resulted in a
longer shelf life than those that had not been
irradiated.
-
-
UAMS Team Unveils
Pathogen-Fighting Agent
-
- A major discovery by researchers at the
University of Arkansas for Medical Sciences offers global
possibilities for helping to ensure the safety of the world's
food supply.
-
- A research team that includes Food Safety
Consortium scientists at UAMS headed by Danny Lattin announced
in September the application of a new product in the food
processing industry and elsewhere. "Quaternary ammonium
compounds have been used for decades in mouthwashes and throat
lozenges," Lattin explained. "We found that this chemical
is safe and kills E.coli, Salmonella, Listeria, Campylobacter
and other bacteria. In addition, it has a preventive effect.
Once applied, it prevents recontamination by bacteria that may
present themselves afterwards."
-
- The project began as an effort supported by
funds from the Food Safety Consortium. The research team
disclosed its findings to the university, and the institution
sought a "use patent" for the product from the U.S. Patent
Office. The first of several patents was granted in 1994, and
developmental work on the project has continued since then.
-
- Members of the research team are Lattin,
Philip Breen, Cesar M. Compadre and E. Kim Fifer &emdash;
faculty members of the UAMS College of Pharmacy at the time of
the discovery &emdash; Hamid Salari, UAMS research associate,
and Phillip V. Engler, research consultant. Lattin has
since accepted the position of dean of the College of Pharmacy
at South Dakota State University. Michael F. Slavik, the
remaining scientist/inventor, is a faculty member at University
of Arkansas in Fayetteville.
-
- This product is now the foundation of a new
Arkansas company, Safe Foods Corp., which will seek the
required federal approvals from the Food and Drug
Administration and the U.S. Department of Agriculture and
present it to the global marketplace.
-
- "We believe the necessary approvals will be
forthcoming within the next year," Ward said. "There is a
tremendous worldwide market for this product. Food processors
in Arkansas, around the nation and from abroad have already
expressed an interest in it," UAMS Chancellor Harry Ward said.
-
- Curtis Coleman, president and CEO of Safe
Foods Corp., said the burden for commercialization of the UAMS
patents now rests upon the company's shoulders. UAMS and Safe
Foods signed an agreement in June 1999 that allocated the
exclusive worldwide rights to the patents to Safe Foods. Safe
Foods has performed necessary marketing research, conducted
pilot projects at food processing plants and secured
international intellectual property protection. The next step
will be to obtain regulatory approval for the product from the
federal agencies. It has already been trademarked
internationally as Cecure.
-
- "This is a wonderful example of how basic
scientific research can lead to solutions to problems facing
humanity," Lattin said. "It demonstrates the true value
of basic science research. This effort also shows that
university researchers can collaborate with the business sector
to address societal needs."

Food Safety
Digest
By Dave Edmark
- Tyson Foods is becoming the first major
player in the poultry industry to irradiate its products. Tyson
of Springdale, Ark., announced in September that it had entered
into an agreement with Titan Corp. of San Diego. Tyson will use
Titan's electron beam pasteurization system at Titan's facility
now under construction in Sioux City, Iowa. The two companies
are preparing for a market test of irradiated products in the
spring of 2000.
-
- Tyson, the world's largest poultry
producer, endorsed irradiation as a scientifically proven safe
process "which dramatically reduces harmful bacteria in food
products including poultry." The company also noted that
irradiation can add days to the shelf life of refrigerated
products.
-
- Tyson acknowledged that irradiation is not
the sole remedy to food safety problems because it also reduces
the numbers of good bacteria that compete with harmful
bacteria. "We strongly advocate continued adherence to the
HACCP principles, good manufacturing practices, standard
sanitation operating procedures and other preventive programs
to be used in conjunction with cold
pasteurization."
-
- Tyson said it would offer its irradiated
products as alternatives to some of its existing products for
customers who decide to choose them over its non-irradiated
products. "The long term consumer demand and the ability of the
marketplace to support the cost of this technology will be our
&emdash; and we believe the industries' &emdash; keys to future
expansion," the company said.
-
- * * *
-
- Irradiation continues to make news on other
fronts. In September, a coalition including food manufacturers
and meat packers asked the Food and Drug Administration to
extend irradiation to processed ready-to-eat meat and poultry
products, fruits and vegetables, the agribusiness newspaper
Feedstuffs reported.
-
- The U.S. Department of Agriculture Food
Safety and Inspection Service regulates meat and poultry and is
empowered to approve new uses of irradiation. But the FDA must
first approve any new use of irradiation as a food
additive.
-
- Irradiation is currently on the verge of
being fully authorized for raw meats. FDA and FSIS have
approved the process and FSIS is completing the specific rules
that will govern its application.
