win victory against listeria threat
American scientists believe they have made a major advance
in the battle against a bug of major concern to food processors.
from Texas A&M University say a new product called acidified calcium sulphate
is showing promise as a way of killing listeria monocytogenes in products such
as luncheonmeats and certain cheeses. "Our goal was ... to ensure that listeria
was killed and had very little opportunity to grow after that," said Dr Jimmy
Keeton, professor with the department of animal science at Texas A&M. Foodborne
listeriosis is most commonly associated with ready-to-eat products such as frankfurters,
hotdogs, luncheonmeat, smoked fish and some soft cheeses.
Listeria can be
introduced from the environment or from staff in a processing plant. The risk
is greatest to pregnant women and those who are debilitated, and one New Zealand
woman lost her unborn twins from contracting listeria through eating mussels.
It can cause flu-like symptoms, meningitis, spontaneous abortions and prenatal
septicaemia. Last October America's second-largest poultry company, Pilgrim's
Pride, recalled 12.4 million kg of ready-to-eat chicken and turkey products in
what officials said was the largest meat recall in US history.
a real concern about from the time ready-to-eat products are cooked until the
time they are packaged that they not become contaminated with pathogens, specifically
listeria monocytogenes," Keeton said.
When these products are cooked,
they are pasteurised and the listeria is killed. "Assuming the product is
cooked adequately, the risk of contamination comes from the surface," he
said. Research had already shown that adding substances such as lactic acid and
sodium lactate created microbiological "hurdles" to organisms such as
listeria. But these were not considered entirely effective against the regrowth
of the organism. However, the acidified calcium sulphate, an organic acid-calcium
sulphate combination, showed potential to not only kill the listeria on the surface
of products, but also to keep it from coming back. Guill Leroux, food safety team
leader at AgResearch Mirinz, the meat industry research institute in Hamilton,
said the American findings looked promising. "It looks potentially a good
one to use. What we would love to do is some research ourselves with some of the
processes." The acidified calcium sulphate could be used for hygiene control
on equipment during processing, for reducing the possibility of products being
recontaminated after processing, and in packaging. The Texas researchers inoculated
commercially made frankfurters with a four-strain listeria monocytogenes "cocktail"
containing 10 million micro-organisms per gram. "You wouldn't expect to find
levels that high. It's a worst-case scenario, so if you're going to get protection,
you should get it at this point," Keeton said. Each group was then treated
with either a saline solution (the control group), with acidified calcium sulphate,
potassium lactate or lactic acid. The frankfurters were then vacuum-packaged normally,
stored in a fridge at 4C for 12 weeks, and evaluated at two-week intervals. Researchers
found the acidified calcium sulphate killed the listeria on the surface and also
stopped the organism
still at risk from illegal meat

public is still at risk from animal waste products entering the food chain illegally,
a report for the Food Standards Agency warned yesterday.
in legislation and poor controls meant criminals could still sell waste products
and unfit meat, said the agency's waste food taskforce."It
is difficult to quantify the risk to public health from this criminal activity,
but it is clear that the public has been exposed to a serious risk of food-borne
disease and food poisoning as well as the prospect that they have eaten food deemed
as unfit," the taskforce said.Recent
cases include the fraud conviction of one group for selling more than 100 tonnes
of poultry by-products destined for pet food.Poor
controls on transporting by-products from licensed premises is a clear weakness,
the report says. Although British law requires that high-risk waste be sterilised
or stained, this is not the case under European Union law. The report says that
high-risk products could thus be diverted into the food chain and bought by reputable
traders.The report also
says that penalties under the Food Safety Act are too small to deter food fraud.
"It is the availability of economically valuable and usable material and
products that provides the opportunity for fraud," it says.Ministers
have relaxed the "20 day" movement restrictions on cattle and sheep,
which was one of the toughest measures of the 2001 foot-and-mouth crisis. The
restriction on moving animals after purchase was eased to six days following industry
lobbying on the grounds that it had prevented farmers from recovering from the
SHOULD I KNOW ABOUT WASHING FRUITS AND VEGETABLES?
Safety Network Factsheet
fruits and vegetables, including lettuce, present unique food safety challenges.
Although a diet rich in fresh fruits and vegetables is actively promoted as the
cornerstone of a healthy lifestyle, there are risks, they need to be acknowledged,
and they need to be managed.
Fruits and vegetables consumed raw are a particular
concern for food safety. Washing can decrease but not eliminate contamination.
Preventing contamination of fresh fruits and vegetables with microbial pathogens,
dangerous levels of chemical residues, or physical contaminants is the most effective
strategy to assure that these foods are wholesome and safe for human consumption.
a number of outbreaks have been traced to fresh fruits and
were processed under less than sanitary conditions. These outbreaks show that
the quality of the water used for washing and chilling the produce after it is
harvested is critical. Using water that is not clean can contaminate many boxes
of produce. Fresh manure used to fertilize vegetables can also contaminate them.
Alfalfa sprouts and other raw sprouts pose a particular challenge, as the conditions
under which they are sproutd are ideal for growing microbes as well as sprouts,
and because they are eaten without further cooking; this means that a few bacteria
present on the seeds can grow to high numbers of pathogens on the sprouts. Unpasteurized
fruit juice can also be contaminated if there are pathogens in or on the fruit
that is used to make it. Washing produce thoroughly with potable running water
is considered the best way to remove dirt and residue however fruits and vegetables
that have firm surfaces, such as melons, potatoes and carrots can also be scrubbed.
Rinsing with vinegar, baking soda, or chlorine bleach can alter the taste of the
produce and chlorine bleach may be toxic if too concentrated Information Sources:

Agriculture is a significant
factor in antibiotic overuse and resistance
"Combating antibiotic resistance" (Editorial, Dec. 23/30, 2002 [see
link at bottom, ed.]): Your editorial did an admirable job of describing recent
successes in helping to cut overuse of antibiotics in human medicine. The AMA
also deserves recognition for its efforts to reduce antibiotic overuse in other
contexts, namely agriculture.
AMA House of Delegates has adopted a policy, original drafted by us, to reduce
agricultural use, and phase out nontherapeutic use, of medically important antibiotics
to livestock and poultry.
most large-scale swine, poultry, and beef-cattle operations, animals routinely
receive nontherapeutic antibiotics in feed without a veterinarian's prescription
not to treat disease, but rather to promote faster growth and to prevent the diseases
that otherwise would result from the stressful, unsanitary conditions under which
the animals are grown. Legislation that would address this issue has been previously
put forth by Sen. Edward Kennedy (D, Mass.) and Rep. Sherrod Brown (D, Ohio) and
was supported by the AMA. Those lawmakers have announced that they will reintroduce
it in the current session of Congress.
overuse of antibiotics in humans is widely regarded as the principal cause of
antibiotic resistance in human pathogens, agricultural overuse also plays a role.
most obvious connection is via food from zoonotic pathogens such as Salmonella
and Campylobacter. But because bacteria can readily transfer resistance genes
via plasmid exchange, agricultural use of antibiotics may contribute to the problem
in other ways as well -- particularly given the massive usage of antibiotics and
other antimicrobials in animal agriculture (totaling 70 of all antimicrobials
used in the United States by some estimates).
addition to contaminating foodstuffs, resistant bacteria also can colonize workers
and contaminate the environment when agricultural waste is used as fertilizer.
Experience in Europe and at some U.S. facilities shows that routine use of antibiotics
is unnecessary at well-operated agricultural operations.
applaud the AMA for its leadership in working to end this unwise practice.

Milk Still Safe to Drink - Health Adviser
senior food safety official says New Zealand milk is still safe to drink, despite
publication today of medical research linking A1 proteins in milk with a high
incidence of juvenile diabetes and high death rates from some types of heart disease.
can see no reason for changing labeling or advice about milk, as part of a balanced
diet," New Zealand's Food Safety Authority principal public health medical
adviser Dr Bob Boyd said.
and nutrition workers, as well as farmers and marketers in the dairy industry
are concerned that publicity about the research might cause some families to reduce
their consumption of dairy products.
are particularly worried about people with young children switching away from
drinking milk and missing out on the health benefits milk brings.
the moment all New Zealand cows' milk contains the proteins, but a biotechnology
company, A2 Corp, which helped fund research published in the latest Medical Journal,
plans to soon launch an A2 product in supermarkets.
research analyzed risk factors in 22 countries and concluded there were strong
links between A1 milk and some forms of heart disease and diabetes.
Boyd said people concerned about heart disease would be better to reduce their
risk by getting more exercise, quitting smoking and lowering the levels of saturated
fats in their diet.
the emphasis we're still going to put on this subject at the moment," he
Dr Boyd said
two of the nation's top epidemiologists, a Geneva-based bureaucrat at the World
Health Organization, Professor Robert Beaglehole and a professor of epidemiology
at Auckland University, Professor Rod Jackson, had commented today that it was
not yet clear what type of research was needed to efficiently investigate the
role that milk proteins played in causing disease.
you be testing animals, should you be doing studies in animals, should you look
at people who have got heart disease and what their diet was when they were younger?"
It was these
issues which the Health Research Council would have to sort out if public funds
were put into such research.
Beaglehole and Prof Jackson said in an editorial in the New Zealand Medical Journal
that basic research carried out in Auckland ?suggesting links between the A1 protein
found in most New Zealand milk and coronary heart disease and juvenile diabetes
?should be followed up.
attraction of suggestions that health risks could be lowered by switching from
one type of milk to another was the simplicity of improving public health, they
be reasonably straightforward to change New Zealand dairy herds to produce only
A2 milk," they said. "The intervention would require no change in behavior
by New Zealanders, and could be implemented with little personal difficulty for
substantial health gain.
they emphasized the greatest gains would come from New Zealanders reducing their
blood pressure, stopping smoking, and taking up exercise and diets high in whole
grains, fruits and vegetables with a low proportion of saturated fats.
Dairy Board said in August 2000 that it could put milk free of A1 protein on shop
shelves within a year if the health benefits were proven.
protein is found in 80 percent of New Zealand milk and much of the rest of the
developed world's dairy products. 1/24/03
