measure moulds in cornflake brands
of Article: http://www.bakeryandsnacks.com/
02/09/2005 - Concentrations of
harmful moulds called fumonisins were higher in organic samples of cornflakes,
finds an investigative study on over 200 samples of this popular breakfast cereal.
from Ghent University, the Catholic University of Louvain in Belgium and the Agricultural
and Biotechnology Centre in Hungary screened 205 cornflake samples, conventionally
produced and organic, purchased from retail outlets in Belgium, for the natural
occurrence of fumonisin B1 (FB1), B2 (FB2), and B3 (FB3).
are produced by several species of the genus Fusarium which infect the grain of
developing cereals such as wheat and maize. They include a range of mycotoxins
including the fumonisins, which affect the nervous systems of horses and cause
cancer in rodents.
In addition to infecting the grains, fumonisins are associated
with foods derived from maize such as polenta, corn snacks and cornflakes.
UN's 56th Joint FAO/WHO Expert Committee on Food Additives has set a provisional
maximum tolerable daily intake (PMTDI) for nephrotoxicity at 2 microgram per kg
of fumonisins B1, B2, and B3, alone or in combination, per kg of bodyweight per
Cooking in alkaline water can reduce fumonisin levels in food products
and baking, frying and extrusion processes at temperatures around 190 o C can
also diminish their presence.
The scientists in the study practiced rapid
screening using a flow-through enzyme immunoassay method to demonstrate the practicability
of a screening test, coupled to a validated confirmatory LC-MS/MS method for the
management of food safety risks.
FB1 concentrations ranged from not detected
to 464 microgram/kg with mean and median concentrations of respectively 104 ¡¾
113 and 54 microgram/kg.
For FB2 and FB3, the concentration ranges varied
respectively from not detected to 43 microgram/kg and from not detected to 90
Concentrations of fumonisins were higher in the organic samples,
significantly so in the case of FB1.
But the scientists concluded from the
statistical tests that the agricultural practice did not have any significant
effect on the fumonisin concentrations, but that the variation between different
batches was significant.
Although they reported that there were no significant
differences in fumonisin content cornflake brands.
Assessment on Vibrio vulnificus in raw oysters - Pre-publication copy now available!
FAO Risk Assesment
FAO and WHO initiated
a risk assessment on Vibrio spp. in seafood in 2001. An ad hoc expert drafting
group was established to examine the available relevant information and undertake
the risk assessment. Their work has been reviewed and guided by two expert consultations.
Also in the course of the work, updates and interim replies to their questions
posed have been provided to the Codex Committee on Food Hygiene (CCFH) and the
Codex Committee on Fish and Fish Products (CCFFP).
Essentially five risk assessments
have been undertaken as follows:
Vibrio parahaemolyticus in raw oysters consumed
in Japan, New Zealand, Canada, Australia and the United States of America.
parahaemolyticus in finfish consumed raw.
Vibrio parahaemolyticus in bloody
clams consumed in Thailand.
Vibrio vulnificus in raw oysters consumed in the
United States of America.
Choleragenic Vibrio cholerae in warm-water shrimp
in international trade.
The risk assessments are currently being peer-reviewed
and will be published in early 2005.
call for hepatitis A vaccinations for kids

Drs. Jules Dienstag and Loriana Di Giammarino of the Harvard Medical School argue

In areas of the

experience, Dienstag and Di Giammarino contend, provides evidence of just how
vulnerable adults have become -- 18 percent of those exposed fell sick and one
out of four people who were sickened ended up in the hospital. At least three
people died; the journal lists three deaths, though the death of a fourth patient
months later is included in media reports.
all children instead of only those at high risk would not be cheap, the Harvard
doctors acknowledged, but half of all people who get hepatitis have no known risk
factors and it is impossible to eliminate or predict foodborne outbreaks.
the costs of treating patients with severe disease and the public health costs
for responding to outbreaks are considerable. It cost $46,000 to treat people

meat lipids can be oxidized during processing, and cooking can cause rancidity.
Irradiation especially accelerates lipid oxidation. However, laboratory experiments
at the University of Arkansas have shown that infusing extracts of grape seed

lipid oxidation process, making the product more palatable and extending its shelf
Green tea and grape seed extracts may serve as alternatives to synthetic
antioxidants such as TBHQ.
Other recent studies at Arkansas show that grape
seed extract increased the lightness and decreased the redness and hardness of
skinless, boneless chicken breast meat. The green tea infusions were found to
prevent and minimize sensory changes during irradiation. Panels of sensory testers
have found no significant difference in taste between irradiated and non-irradiated
chicken breast infused with grape seed and green tea extracts.

Will Debut New Pasteurization Technology At Worldwide Food Expo
Source of Article: http://www.packagingnetwork.com/
RapidPak will feature
the new SP Technology for flash pasteurization of pre-cooked food products. A
significant improvement over conventional surface pasteurization which can take
up to 20 minutes to complete, SP Technology takes just 1.5 seconds and causes
a 3 log reduction in Listeria monocytogenes.
The SP module can be retrofitted
into existing RapidPak packaging lines and has no effect on line speed. It uses
a quick burst of high pressure steam that adds no additional thermal load to the
product. The process has no effect on sensory characteristics and minimizes purge.
Low capital cost and minimal floor space requirements make it a simple and easy
addition to food packaging systems. SOURCE: RapidPak

fisherman dies from saltwater-borne bacterial infection
An Eastern Shore Maryland
fisherman died from a rare bacterial blood infection caused when an open wound
on his body came in contact with contaminated marine life or saltwater, health
authorities said. Dr Ann H Webb, deputy health officer for Talbot County, refused
to release details about the death caused by Vibrio vulnificus, saying that she
wanted to protect the privacy of the patient¡¯s family. But Webb did say that the
fisherman was healthy until a skin abrasion became infected while he was fishing
in July 2005 on the Chesapeake Bay.
¡°It¡¯s very rare, and it shouldn¡¯t cause
any panic,¡± Webb told The (Baltimore) Sun. ¡°But we¡¯d like to make people aware
that when the Bay temperature rises, they should not eat raw seafood. And, if
they go swimming, they should not have any open lesions, and they should rinse
themselves off well after they leave the water.¡± The last confirmed death from
vibrio in Maryland occurred more than a quarter-century ago, health experts said.
fatal, vibrio infections are rare in the Chesapeake region. About 100 people a
year in the US become sick from the bacteria when they eat raw oysters or touch
contaminated fish or crabs, according to the Centers for Disease Control and Prevention
(CDC). About 38 per cent of the people who contract vibrio infections die.
most important thing is that if anybody receives a wound at the seashore, they
should wash it carefully,¡± said John Painter, an epidemiologist with the CDC.
¡°If they see any changes in the wound, they should go to a physician, who should
culture the bacteria and consider treatment with antibiotics,¡± he said.
vulnificus is a naturally occurring waterborne bacterium similar to the bacterium
that causes cholera. Vibrio is commonly found in the Gulf of Mexico and other
warm bodies of saltwater, reproducing more as temperatures rise. It normally causes
serious problems only to people with weakened immune systems, according to Rita
Colwell, a microbiologist at the Johns Hopkins Bloomberg School of Public Health.
¡°Vibrio is notorious for getting into wounds, and once it gets into the blood
system, it¡¯s devastating. It essentially liquefies the internal organs,¡± she said.

The state Division of Public
Health has reported 2 recent botulism outbreaks in Interior Alaska villages, but
it hasn't named the villages. Health officials sent nurse practitioners to 2 separate
Yukon-Kuskokwim Delta villages Mon, 22 Aug 2005. They went to help with 4 people
who became ill after eating fermented salmon, a traditional village meal.
declining a request by KTUU-TV to name the affected villages, Dr. Richard Mandsager,
the director of public health, says botulism is not contagious and poses little
risk to the public. "The communities are small, so the risk of stigmatizing
either individual or providing information that could lead to identifying individuals
is very, very high, so we don't," he said.
Since 1995, the state has averaged
8 cases of botulism a year.

to introduce new rule on feed ban soon
by Pete Hisey on 9/1/2005
The proposed rule on ruminant-to-ruminant feed restrictions
that the Food and Drug Administration announced in early 2004, then pulled off
the table, will finally emerge sometime in the next month or two, according to
Dr. Steve Sundlof, director of the Center for Veterinary Medicine.
at a press conference on Tuesday, Sundlof said that the revised rule was on the
way, but he would not specify which of the earlier proposed rule's restrictions
would remain. The Advanced Notice for Proposed Rulemaking proposed removing all
specified risk material (SRMs) from all animal feed and considered other, more
moderate steps such as removing poultry litter, plate waste and bovine blood from
all feed and dietary supplements.
the press conference, Agriculture Secretary Mike Johanns said that Japan would
not be justified in using that announcement as a reason to hold up reopening its
market to American beef. "Japan would not be justified under any science,
under any view of the world, to adopt that viewpoint," Johanns said.
however, were skeptical, noting that it could be a year before the proposed rule
is made final and that this would be a custom-made excuse for Japan to keep its
market closed for at least that long and possibly longer.
was also asked why the proposed rule has been delayed so long. He responded that
the initial recommendations were made when it appeared that the United States
might have significant exposure to bovine spongiform encephalopathy. The expanded
surveillance program that APHIS announced at about the same time indicated that
the infectivity in the American herd was far lower than at first feared, and FDA
reexamined its recommendations to bring them in line with actual risk.
are some of the reasons it has been delayed," Sundlof said. "It's a
complicated regulation; it involves a lot of material that will have to be disposed
of in some environmentally friendly way, and so we have to be very thoughtful
about how we propose a rule that has minimal environmental impact yet does the
greatest amount to reduce the actual risk of BSE in cattle."
