Breakthrough
on food hygiene news.bbc.co.uk The
pressure chamber also works on products like ham Northern Ireland scientists
are trumpeting a food safety breakthrough which promises to put bacteria under
pressure. They have been working to find a way to keep food fresh without
resorting to chemical preservatives. The
answer it seems is to put them under pressure - big pressure. Scientists
at Queen's University in Belfast believe the answer is a pressure chamber which
kills the bugs, but nothing else. Fresh
flavour Dr Margaret
Patterson of the Department of Agriculture said the treatment of orange juice
had been a big success. "Pressure
will destroy many of the bacteria and the yeasts that normally spoil orange juice
- but will not affect the flavour and the colour," she said. "This
means you will have a freshly tasting juice for up to three weeks in the fridge,
with that very fresh flavour and no preservatives." However,
the pressure chamber also works on products like ham and shellfish. "Oysters,
for example, are quite hard to open and are sometimes quite dodgy in terms of
food safety," said Dr Patterson. Dr
Patterson said orange juice treatment was a success "The pressure will
help the shell to loosen and meat to fall out." At
45,000 lbs per square inch, a bug's life is no life in the laboratory. Dr
Don Johnston of the Department of Agriculture said the pressure was equivalent
to the weight of three elephants on a strawberry. "It
is important to achieve these high pressures in order to make the food safe,"
he said. | | | | |

Safety for Your Family Thu Mar 6, 7:00 PM ET KidsHealth.org
http://story.news.yahoo.com You probably have lots of concerns about the
foods you give to your child. Is it a nutritious meal? Will he eat it? Is there
too much fat? But one thing that may not cross your mind as you're slicing and
dicing in the kitchen is food safety.Why is food safety important? And how can
you be sure your kitchen and the foods you prepare in it are safe? Keep reading
to find out. Why Food Safety Is Important Proper food preparations are necessary
to prevent the spread of bacteria, such as E. coli, and foodborne illnesses, such
as salmonellosis, campylobacter infections , and listeriosis. These preparations
include knowing how to select foods in the grocery store, how to store them in
your kitchen, and how to clean your kitchen.
In
the Grocery Store The grocery store is your first stop on the way to food safety.
To ensure the freshness of your refrigerated items (meat, dairy, eggs, and fish,
for example), put these in your cart last. If your drive home is longer than 1
hour, you might want to consider putting these items in a cooler to keep them
fresh.
When
purchasing packaged meat, poultry, or fish, be sure to check the expiration date
on the label. Even if the expiration date is still acceptable, don't buy fish
or meats that have any unusual odors or look strange. Ground beef should be red,
not any shade of brown; a whole fish is fresh when its eyes are clear, not milky.
In the refrigerator, put meat, poultry, and fish in separate plastic bags so that
their juices do not get on your other foods. It's also important to check inside
egg cartons. You should make sure the eggs, which should be grade A or AA, are
clean and free from cracks.
Don't
buy: fruit with
broken skin (bacteria can enter through the opening in the skin and contaminate
the fruit) unpasteurized ciders or juices (they can contain harmful bacteria)
prestuffed turkeys or chickens In
the Kitchen Before you put the groceries away, check the temperature of your
refrigerator and freezer. Your refrigerator should be set for 40 degrees Fahrenheit
(5 degrees Celsius), and your freezer should be set to 0 degrees Fahrenheit (-18
degrees Celsius) or lower. These chilly temperatures will help keep any bacteria
in your foods from multiplying. The
first items you should put away are those that belong in the refrigerator and
freezer. Keep eggs in the original carton on a shelf in your refrigerator (most
refrigerator doors do not keep eggs cold enough). Raw
meat, poultry, or fish should be cooked or frozen within 2 days. Raw ground meats
can be stored in the freezer for a maximum of 4 months; cooked meats can be frozen
for a maximum of 3 months. It's
important to refrigerate any leftovers as soon as possible after cooking. If left
to sit at room temperature, bacteria in the food will multiply quickly. To facilitate
the cooling process, you might want to divide the leftovers into smaller containers.
Also, remove stuffing from poultry after cooking and store separately in the refrigerator.
Consume leftovers within 3 to 5 days or throw them out. Follow
these handling and cooking guidelines to prevent foodborne illness in your family:thaw
meat, poultry, and fish in the refrigerator or microwave, never at room temperature
cook thawed meat, poultry, and fish immediately throw away any leftover
uncooked meat, poultry, or fish marinades cook meat until the center is no longer
pink and the juices run clear cook crumbled ground beef or poultry until it's
no longer pink use a meat thermometer to tell whether meats are cooked thoroughly
- most thermometers indicate at which temperature the type of meat is safely cooked,
or you can refer to the recommendations below (place thermometer in the thickest
portion of the meat and away from bones or fat) scrub all fruits and vegetables
with plain water to remove any pesticide residue or dirt remove the outer leaves
of leafy greens, such as spinach or lettuce ANTIMICROBIAL
TESTING METHODS & PROCEDURES (ATMP) March
6, 2003 EPA, Office of Pesticide Programs http://www.epa.gov/oppbead1/methods/atmpindex.htm The
Standard Operating Procedures (SOPs) for antimicrobial testing methods describe
the methods used by the OPP Microbiology Laboratory to determine the efficacy
of hard surface disinfectants against Staphylococcus aureus, Pseudomonas aeruginosa,
Salmonella choleraesuis, and Mycobacterium bovis BCG. Methods are available
for liquid, spray, and towelette formulations. The SOPs were derived from official
AOAC (AOAC International) methods. The specific AOAC method is cited in each SOP.
The SOP for testing towelette products is a modification of AOAC's Germicidal
Spray Products Test (961.02). In addition to the test method SOPs, which may
be downloaded from the ATMP Index, several SOPs which support the testing activities
are listed (e.g., SOPs for carrier screening, carrier counts, test microbe maintenance).
Copies of those SOP's may be requested from the contacts listed below. For

Heavy
Metal Fish BY NANCY SHUTE http://story.news.yahoo.com/ Fish is good
for you. So sushi-lovers in California may be surprised by the new signs popping
up in supermarkets. "Warning! Pregnant and nursing women, women who may become
pregnant, and young children should not eat the following fish: swordfish, shark,
king mackerel, tilefish. They should also limit their consumption of other fish,
including fresh or frozen tuna." The supermarket warnings, mandated by
the state attorney general, are the latest effort to reduce the risks posed by
mercury, a heavy metal that contaminates almost all seafood. New concerns about
its possible role in heart disease and immune system disorders are adding to the
well-known dangers of mental retardation and developmental problems in children
exposed in the womb. Fish may be superb "brain food," high in protein
and omega-3 fatty acids, but its benefits, we now find, may come with some perilous
costs. The alarm comes just when plans to reduce the main source of this mercury--emissions
from coal-fired power plants--are being scaled back by the Bush administration.
At the same time, more and more Americans are heeding the public-health message
that eating fish helps combat obesity, heart disease, stroke, and other major
ills. Federal agencies are further adding to the confusion by squabbling over
how much mercury a person can safely eat. "It's complicated," says Lynn
Goldman, a pediatrician and professor of environmental health at the Johns Hopkins
University Bloomberg School of Public Health. "With food safety you're not
just talking about toxicity but about nutritional benefit."Toxic food chain.
Fish is very nutritious, and mercury is unquestionably toxic. In the 1950s, women
in Minimata, Japan, exposed to high levels in fish gave birth to children with
grievous birth defects. Since then, it has become clear that even low levels of
mercury exposure in women can cause neurological problems in their children, affecting
language, hearing, and movement. Today, the Environmental Protection Agency (news
- web sites) estimates that 8 percent of American women of childbearing age have
blood mercury levels that could endanger their children. As a result, over 60,000
children are born each year at risk of lifelong problems, according to the National
Academy of Sciences (news - web sites). Young children also can be harmed by mercury
in the food they eat, because their brains are still actively developing. (The
effects of childhood exposure have caused parental concerns about mercury in vaccines,
too. Story, Page 44.)Fish pick up methylmercury, a form of the element that binds
to the protein in their bodies, from microorganisms in oceans and lakes. As big
fish eat little fish, they absorb the methylmercury in their prey. Thus big, old
fish such as swordfish, shark, and tuna carry more of the metal than salmon and
shrimp. In California, consumer groups tested fish bought from seven stores, including
Albertson's, Safeway, and Trader Joe's. Mercury levels in swordfish, tuna, and
shark exceeded a statute's draft threshold. A lawsuit filed by the state attorney
general in January prompted the new warning notices.It's no small irony that the
fish that tend to be most heavily contaminated with methylmercury are also the
most expensive. After a patient suffering from hair loss was diagnosed with high
methylmercury levels, Jane Hightower, a primary care physician in San Francisco,
wondered if the rest of her population of doctors and dotcommers were putting
themselves at risk by feasting on sushi and other gourmet fare. In a study to
be published in the April Environmental Health Perspectives, she tested 89 patients
and found that the majority had blood mercury levels above the Environmental Protection
Agency's safety threshold of 5 micrograms per liter; one registered a whopping
89.5 micrograms. "People were ill," she says, with symptoms including
fatigue, headache, memory loss, and joint aches. Mercury levels generally dropped
after patients abstained from fish for six months.But for most Americans, sushi-grade
tuna is not on the menu. Canned tuna, the kind you can get for 39 cents, often
is. Each year Americans eat 3.4 pounds of canned tuna per person--far more than
any other fish. The Food and Drug Administration (news - web sites) says that
canned tuna usually has about half the mercury of fresh tuna. That's largely because
chunk light tuna comes from smaller fish than those used for fresh fish. But in
2000, the state of Florida found that 43 percent of the canned tuna it tested
would be questionable under EPA guidelines. Ten states now urge women of childbearing
age to restrict consumption to one or two cans a week. (For example, see http://www.doh.wa.gov/fish/Lim
itsGraph.pdf.) Conflicting advice. Figuring what's safe is complicated, because
it depends on a person's body weight, sex, and age, and also on the amount of
mercury in a particular fish, which varies widely. And the government isn't helping
much. The FDA allows five times as much mercury in fish as does the EPA; a 2000
report by the National Research Council (news - web sites) backed the EPA's more
conservative approach. In 2001, the FDA urged women of childbearing age and small
children to avoid eating tilefish, swordfish, shark, and king mackerel (box).
But the FDA has so far failed to issue guidelines on tuna and children's consumption,
even though its own advisory board asked it to do so last year. David Acheson,
chief medical officer for the FDA's Center for Food Safety and Applied Nutrition,
says the agency hopes to act by fall. The FDA plans to rely on public education,
rather than regulation, to reduce the risk, he says. "Our whole approach
to tuna and methylmercury is to make sure that the folks who need to limit their
exposure get our message.""The FDA is falling flat," says Jane
Houlihan, research director of the Environmental Working Group, which is studying
the health aspects of canned tuna. "Canned tuna is very important. It accounts
for about half of the mercury in the public's diet." She recommends canned
salmon as a cheap and nutritious, low-mercury alternative. Researchers are only
now starting to look into how methylmercury exposure may affect people through
the life span. Recent studies, including one in last November's New England Journal
of Medicine (news - web sites), suggest that men with elevated mercury levels
may have more heart attacks. Animal studies indicate that low-level mercury exposure
may make people more susceptible to autoimmune diseases and other immune problems.
Hightower advises her patients to quit eating grilled tuna every single day for
dinner and get more variety in their diet. "We're omnivores," she says.
"Eat everything, but not a whole lot of anything." She still eats sushi.
"But I don't eat it very often."
Which fish is safe? The
U.S. Food and Drug Administration considers mercury levels below 1 part per million
acceptable, though it warns against shark and mackerel, too. The Environmental
Protection Agency has a lower threshold, about 0.2 ppm. FISH

ABSTRACT: The
Enter-net surveillance system received results of antimicrobial sensitivity tests
for isolates from over 27 000 cases of human salmonellosis in 2000 in 10 European
countries. Almost 40% of isolates were resistant to at least one antimicrobial,
with 18% multiresistant. Resistance to ampicillin, streptomycin, sulphonamides
and tetracyclines was common, with over 20% of isolates resistant to at least
one of these antimicrobials.Clinical resistance to ciprofloxacin was rare, with
only 0.5% of isolates exhibiting such resistance (MIC >1.0 mg/l). Resistance
to nalidixic acidcoupled with a decreased susceptibility to ciprofloxacin (MIC
0.25-1.0 mg/l) was more common, with 14% of isolates showing these properties.
Resistance to third-generation cephalosporins was rare with only 0.6% of isolates
resistant to cefotaxime. In all countries multiple resistance was most common
in Salmonella enterica serotype Typhimurium, with 51% of isolates multiresistant
in total. In England and Wales multiple resistance was also prevalent in S. Virchow
and S. Hadar, whereas in other countries multiple resistance was common in serotypes
such as S. Blockley. | | Current

Citizen B6 The Ottawa law firm Nelligan O'Brien Payne and the Toronto law firm
McPhadden Samac Merner Darling will, according to this story, join forces to argue
a class-action lawsuit on behalf of 536 people who were sickened after eating
store-bought salad in the two cities last year. The story says that the people,
many of them from Ottawa, were believed to have been infected by shigella bacteria,
which can cause diarrhea, cramps, vomiting and nausea, after they ate a Greek-style
pasta salad made by Tiffany Gate Foods Inc. of Toronto. The salad was sold at
Ontario grocery stores, including Loblaws, Loeb, A&P and Your Independent
Grocer stores. A statement from the two law firms yesterday said they decided
to work together because two class-action lawsuits can't proceed from the same
claim. Tiffany Gate president Adolph Zarovinsky has said the company will defend
itself against the legal action. He has said tests done by the company found no
sign of shigella contamination in its pasta. Current

TEST DEVELOPER TO WORK AT UNIVERSITY OF ILLINOIS INCUBATOR March 6,
2003 Knight-Ridder Tribune Don Dodson, The News-Gazette, Champaign-Urbana,
Ill. CHAMPAIGN, Ill.-- Myung Kim is, according to this story, developing processes
that can quickly identify the presence of salmonella, and his company, Kim Laboratories,
is one of six companies so far that have agreed to lease space in EnterpriseWorks,
the University of Illinois' new business incubator at 60 Hazelwood Drive in Champaign.
The 43,000-square-foot building in the UI Research Park should be ready for occupancy
in about a month. The story goes on to say that food processing companies can
use the swabs to take surface samples from chicken and other foods. The swabs
are then put in flexible test tubes, where they'll come in contact with a reagent
liquid. The swabs are squeezed to extract any salmonella present. A specially
designed test strip is then placed in the test tube, and the strip indicates in
five minutes whether salmonella is present. Another product, the Insti-Tech filter,
would be used by hospitals to determine whether patients have contracted salmonella.
Stool samples are taken, and when the filter paper comes in contact with them,
it indicates the presence of salmonella. Kim estimates the market for Insti-Tech
products at $140 million a year in the United States alone. He believes he can
provide the technology for about $4 a test. Some processing facilities currently
pay up to $25 per test, he said. Among the possible users: meat processors such
as Tyson Foods and ConAgra and dairy products processors such as Kraft Foods. Receives
Approval for Innovative Food Safety Technology http://www.stockhouse.ca/news/ Company
set to launch first Genevision(TM) test - Warnex
Inc. announced that the evaluation of the independent validation of its proprietary
food safety test for the detection of Salmonella had been completed and that it
had been granted 'Laboratory Procedure'status in Canada. The Company is now set
to market its pathogen detection platform. The
test for the detection of Salmonella uses Warnex's proprietary Genevision technology
and represents the first in what is expected to be a series of Microbiological
Methods Committee (MMC) evaluations for various pathogens including Listeria and
E.coli O157:H7. The
current annual worldwide market to test for food-borne pathogens is estimated
at $5 billion. 'Having
achieved this landmark milestone we can now launch a commercial product into a
lucrative market opportunity'said Mark Busgang, President and CEO of Warnex. 'This
validation from an internationally respected organization such as the Canadian
Food Inspection Agency (CFIA) provides an independent confirmation of the capability
of the Genevision technology.' Warnex
now intends to begin a limited rollout of Genevision to select customers to expand
its installation and logistical experience, prior to a broader rollout in the
second half of 2003. The
'Laboratory Procedure'status was granted by the MMC, Health Canada, which based
its decision on the thorough evaluation of the test and Genevision technology
performed by the CFIA. The decision is based on rigorous statistical criteria
set by the MMC. A
more detailed description of the test procedure can be found in Volume 3 of the
Health Canada Compendium of Analytical Methods, or at http://www.hc- sc.gc.ca/food-aliment/mh-dm/mhe-dme/compendium/volume_3/e_index.html.
