later this summer. The detector would help food processors in their battle to
maintain the safety of their products. Consumer demand and an increased focus
on food safety through regulator oversight and regulations is a driving trend
in the market.

In the medical world it is a way to rapidly and accurately diagnose disease. When
coated with antibodies the cantilevers bend and resonate to changes in surface
tension and mass when fluids containing disease-related protein molecules attach
By seeing whether
or not the cantilevers react, doctors would be able to determine whether or not
a disease is present, Bausells stated in an announcement about Biofinger. Though
much of the team's research has been carried out into cantilevers, it has focused
principally on creating large-scale tools for use inside laboratories.

bans poultry antibiotic
by Ann Bagel on 8/1/2005 for Meatingplace.com
that the drug could lead to antibiotic-resistant infections in people, the Food
and Drug Administration last week banned the use of Baytril, known generically
as enrofloxacin, in poultry, effective Sept. 12.
Crawford, FDA commissioner, mentioned particular concerns about campylobacter
bacteria, a growing source of illness in humans. He said use of enrofloxacin in
poultry does not eliminate campylobacter from the birds but instead leads to the
development of bacteria resistant to this type of drug. Crawford noted that since
the drug was introduced for poultry in the 1990s, the proportion of resistant
campylobacter infections in humans has risen significantly.
industry groups expressed disappointment with FDA's decision. "Baytril is
a useful medication that is used sparingly and responsibly in the industry,"
said National Chicken Council spokesman Richard Lobb.
loss of this product leaves poultry producers without an important tool to treat
sick poultry, and it will reduce animal health and welfare while increasing animal
death and suffering," said a statement from the Animal Health Institute.

official: Our beef is safe
July 27, 2005
month, according to this editorial, a three-judge panel for the 9th U.S. Circuit
Court of Appeals struck down Judge Cebull's decision, permitting implementation
of the USDA's order. Despite the highly technical nature of the underlying issues,
the appeal court decision makes compelling reading -- because it shows just how
misguided and arbitrary was Judge Cebull's March 2 judgment. O
says that on every crucial issue, the judge seems to have accepted the opinion
of the protectionist-minded plaintiffs over the USDA's informed experts.
best example originates with the question of just how prevalent mad cow is in
Canada's beef herd. Relying on state-of-the-art data and modeling techniques,
the USDA calculated our BSE rate at 0.3-0.4 per million head of cattle -- or about
one case for every 3 million cattle. Yet, the District Court rejected this number,
uncritically and inexplicably adopting the plaintiff's estimate of 5.5 cases per
million head of cattle -- or about 15 times the USDA's estimate. Based on this
bogus number, the editorial says that the judge breathlessly concluded that the
importation of "2-3 million head of cattle from Canada during the remainder
of 2005" presented a "potentially catastrophic risk of danger to the
beef consumers in the U.S."
A further hearing in district court was originally
scheduled for today -- this one relating to R-CALF's request for a permanent injunction
against the USDA's rule. But after reading the 9th Circuit decision, Judge Cebull
announced that "this court will determine whether further hearings are necessary."
Monday's judgment suggests the issue has been decided. Judge Cebull and R-CALF
must both accept the USDA's judgment that Canadian beef is safe.
Canada investigates new research findings on Aspartame
July 19, 2005
from a new study conducted by a research institute1 in Italy to assess the possible
carcinogenicity of aspartame were publicly released in Europe on July 14, 2005
and are expected to be published soon in the European Journal of Oncology.
Canada scientists are reviewing the available information and are collaborating
with scientists in the European Food Safety Authority who are currently attempting
to obtain the detailed observations from the Italian study.
Aspartame is a
non-nutritive sweetener first approved for use in foods and as a table top sweetener
in Canada in 1981. Health Canada scientists evaluated an extensive array of toxicological
tests in laboratory animals, and more recently, a large number of clinical studies
in humans. Aspartame is also currently permitted for use as a sweetener in food
in many countries and its safety has been carefully examined by health authorities
and international expert groups around the world.
The overwhelming body of
scientific evidence supports the safety of this sweetener, when used according
to the provisions of the Food and Drug Regulations. However, as is the case whenever
new information concerning the safety of a product arises, this new information
will be reviewed as soon as it is made fully available. Should any conclusive
evidence be found linking the consumption of aspartame to adverse health effects,
Health Canada will take appropriate action.
In the meantime, based on the limited
new information available, Health Canada does not have a basis for recommending
any dietary changes relating to the use of aspartame.

spikes in 2005: Salmonella sickened more than 450 people in North Carolina alone
WFMY News 2 http://www.wfmynews2.com/
Greensboro, NC -- North Carolina's
State Health Director Leah Devlin, M.D., was cited as saying that in North Carolina,
453 cases of salmonella have been reported in the first five months of 2005, four
times the number of cases reported through all of 2004, and the state's division
of public health believes that the outbreak resulted from ingesting raw or undercooked
In the report, Dr. Devlin was quoted as saying, "The bacterium that
causes Salmonella enteritidis can be found inside seemingly normal eggs, but if
eggs are eaten raw or undercooked, the bacteria can cause sickness and even death."
National Restaurant Association is also trying to increase awareness levels, recommending
that eggs be cooked to 145 degrees, and held there, in order to eliminate salmonella.
Few cooks actually temperature test their egg dishes, in turn preparing many eggs
in styles with soft yolks that don't meet these safe temperature levels, such
as over-easy eggs which are a favorite for dunking toast.
July 28, 2005
Dr. Melinda Rowe, commissioner of the Lexington-Fayette
County Health Department, Kentucky, was cited as saying that Fayette County¡¯s
ongoing shigellosis outbreak is no longer just related to kids sickened in day
care, adding, "This is a community-wide outbreak going on. It¡¯s probably
going to get worse before it gets better.¡±
The story says that the number of
confirmed shigellosis cases has doubled during the past month, bringing the total
since May to 111. A month ago, the vast majority of shigella infections ? 49 of
55 cases ? were among children 4 and under who attend day care.
But, the story
says, the outbreak is expanding. Most troubling to Rowe and other public health
officials is that seven recent cases have sprung up among adults who haven¡¯t had
contact with infected children or day care centers.
Nationally, there are about
18,000 cases of shigellosis reported each year in the United States, according
to the federal Centers for Disease Control and Prevention. But because many milder
cases are not reported, it¡¯s estimated the number is actually closer to 360,000
Children ages 2 to 4 are most likely to get shigellosis and the disease
is more common in the summer.
In 1991, Fayette County also experienced a major
shigellosis outbreak centered around day care centers. Some 186 cases of the disease
were confirmed between January and July that year.
for consumer organizations to promote national food safety systems
Safe Food International
The complete document can be downloaded
The Safe Food International Guidelines
cover eight essential elements for an effective food safety program: Food Laws
and Regulations; Foodborne Disease Surveillance and Investigation Systems; Food
Control Management; Inspection Services; Recall and Tracking Systems; Food Monitoring
Laboratories; Information, Education, Communication, and Training; Funding and
Affordability of the National Food Safety Program.
1. Food Laws and Regulations
Each country must have effective, comprehensive food legislation to give its government
the authority to ensure a safe food supply. Some countries have not developed
specific laws to assure food safety ? or they have developed such laws only recently.
In other countries, food safety laws were drafted decades ago. Frequently, they
do not address emerging hazards, like harmful bacteria, viruses, mycotoxins, pesticides,
and prions, or new innovations, such as genetically modified plants and irradiation.
Consumer organizations should be vigilant in identifying ways in which their national
laws should be implemented, strengthened and modernized. A modern national food
law contains several essential elements. First, it should provide a framework
for an integrated and coordinated food safety system. It should give food safety
authorities effective tools to respond promptly to hazards in the food supply,
especially during emergencies, and to remove hazardous food from the market in
a timely fashion. Finally, it should promote the use of preventative food safety
BBL¢â CHROMagar¢â Listeria Now AOAC¢â-RI Approved!
CHROMagar¢â Listeria is a selective medium for the isolation, differentiation,
and identification of Listeria monocytogenes from food and environmental samples.
BBL CHROMagar Listeria
has been validated by the AOAC¢â Research Institute under the Performance Tested
MethodsSMProgram as a single plate method for the analysis of raw ground beef,
smoked salmon, lettuce and Brie cheese when using FDA BAM, USDA FSIS, AOAC and
ISO methods.1-5 Certificate No. 060501.
BBL CHROMagar Listeria is AOAC-RI approved!
Listeriosis is a foodborne illness caused by L. monocytogenes. It is of particular
concern for immunocompromised patients: cancer, HIV, pregnant women, neonates
and the elderly. Because of the severity of the disease, 20 deaths per 100 cases,
listeriosis is a serious public health and food industry concern. Illness caused
by L. monocytogenes has been associated with deli meats, poultry, soft cheeses,
ready-to-eat seafood, smoked fish, hot dogs, salad greens and inadequately or
unpasteurized milk.6,7 L. ivanovii, rarely found in foods, is pathogenic to animals
and some cases of human listeriosis have been associated with this organism.8
CHROMagar Listeria, as a single plate method, is intended for the isolation, differentiation,
and confirmatory identification of L. monocytogenes/ivanovii based on the formation
of blue-green colonies surrounded by an opaque, white halo in as little as 24
hours from primary enrichment broth. Studies using BBL CHROMagar Listeria for
testing a variety of food and environmental samples demonstrated 99-100% sensitivity
and 100% specificity with a detection level of 1-18 CFU/25 g.9
Announces Final Decision About Veterinary Medicine
U.S. Food and
Drug Administration (FDA) Commissioner Lester Crawford is announcing the Agency's
final decision to no longer allow distribution or use of the antimicrobial drug
enrofloxacin for the purpose of treating bacterial infections in poultry. This
ruling does not affect other approved uses of the drug. This animal drug belongs
to a class of drugs known as fluoroquinolones and is marketed under the name Baytril
by Bayer Corporation.
FDA's Center for Veterinary Medicine (CVM) began proceedings to withdraw use of
this animal drug in poultry because of scientific data that showed that the use
of enrofloxacin in poultry caused resistance to emerge in Campylobacter, a bacterium
that causes foodborne illness. Chickens and turkeys normally harbor Campylobacter
in their digestive tracts without causing poultry to become ill. Enrofloxacin
does not completely eliminate Campylobacter from the birds' intestinal tracts,
and those Campylobacter bacteria that survive are resistant to fluoroquinolone
drugs. These resistant bacteria multiply in the digestive tracts of poultry and
persist and spread through transportation and slaughter, and are found on chicken
carcasses in slaughter plants and retail poultry meats.
bacteria are a significant cause of foodborne illness in the U.S. Antimicrobial
treatment is recommended for people with severe illness as well as the very young,
the elderly, and people with certain medical conditions. Complications of such
infections can include reactive arthritis and, more rarely, blood stream infections.
Early treatment can mitigate symptoms and may decrease the risk of complications.
Fluoroquinolones used in humans are ineffective if used to treat Campylobacter
infections that are resistant to them. This failure can significantly prolong
the duration of the infections and may increase the risk of complications. The
proportion of Campylobacter infections that are resistant to fluoroquinolones
has increased significantly since the use of enrofloxacin in poultry was approved
in the U.S.
has 60 days from the date of the decision to appeal the withdrawal to a U.S. Court
of Appeals. The Final Rule withdrawing approval of the antimicrobial drug enrofloxacin
for the purpose of treating bacterial infections in poultry will be effective
on September 12, 2005.
