E.
coli victims settle claims with restaurants serving California-grown
veggies (Jan. 13, 2005); Knight-Ridder Tribune; By
Joe Livernois, The Monterey Co. Herald, CA. |
|
Victims of an E. coli outbreak allegedly
involving contaminated vegetables grown in Salinas Valley are,
according to this story, settling their claims against the restaurants
serving tainted produce in 2003. But, the story says, the legal
cases continue while the restaurant owners attempt to pin
the blame on Salinas Valley produce companies, and operators
of those produce companies blame the Monterey County Water Resources
Agency.
William Marler, a Seattle attorney representing the victims,
was cited as saying that terms of the settlement agreement between
the restaurants and the approximately 49 victims of the outbreak
are confidential. Fred Gordon, a San Diego attorney representing
Pat & Oscars restaurant and The Sequoias, a retirement facility
in Portola Valley, was cited as saying that not all those claims
have been settled, but most have, and that once the final claims
are settled, the terms of the agreements will be public.
Marler was quoted as saying, "We've resolved our differences.
Both restaurants agreed to settle the claims with the victims
and are now going upstream after the suppliers."
The story says that the suppliers have filed claims against Monterey
County, alleging the county failed to maintain Santa Rita Creek,
resulting in flooding that contaminated a field with toxic substances
and animal waste.
The story notes that a woman at The Sequoias, 85-year-old Alice
McWalter, died after eating raw spinach she got from a self-service
buffet in the facility. She died on Oct. 14, 2003, at Stanford
Medical Center, two days after she became violently ill after
eating a salad from the buffet. At least 16 others at The Sequoias
also got sick, but they all survived, according to Marler.
In Southern California, health officials were cited as concluding
that Pat & Oscars customers treated for E. coli had all consumed
salads provided in pre-mixed, pre-washed packaged lettuce mixes.
Those bagged salads were tracked back to Salinas Valley.
Gordon was further cited as saying his clients filed cross-complaints
against two distributors and the two Salinas Valley produce companies,
Diamond Produce and River Ranch Fresh Foods. Those companies
grew, processed and bagged the vegetables that eventually were
consumed by customers at the restaurant or residents at The Sequoias.
Gordon added that the two Southern California distribution companies
-- FT Produce and Gold Coast Produce -- have settled the case,
agreeing to pay a total of $5 million to Pat & Oscars, but
that the restaurant's case against Diamond Produce and River
Ranch is not yet resolved.
Meanwhile, attorneys for the two produce companies have filed
claims against Monterey County, California.

| Risk
of contracting BSE lower than one in a million: Salmonella, botulism,
E. coli considered deadlier (January 13, 2005) |
|
Even if you sat down and ate a slab of mad
cow steak, your chances of contracting the human variety of BSE
are, according to this story, close to nil. Chris Clark, of the
University of Saskatchewan's Western College of Veterinary Medicine,
was cited as saying that Canada's fourth instance of BSE in cattle
in a population of 15 million cattle across the country -- with
six million of those over the 24-month-old hump, when BSE commonly
emerges -- puts the chances of coming across cattle with mad
cow at less than one in a million, adding, "Since the middle
of last year we have been involved in a very aggressive targeted
surveillance program. Canada committed to testing 8,000 animals
last year, with a ramp up to 30,000 animals this year."
Stephen Moore, chairman of bovine genomics at the University
of Alberta's department of agriculture, was quoted as saying,
"People's perception of the disease is coloured by the fact
that it's not a very nice disease," adding that salmonella,
botulism and E. coli are much more effective killers.

| Wegmans heads Fortune's best-employer
list; (January 12,
2005) |
|
by Deborah Silver for Meatingplace.com:
Wegmans Food
Markets topped Fortune magazine's eighth annual list
of the best 100 companies to work for in America. The Rochester,
N.Y.-based grocery chain, whose motto is "employees first,
customers second," scored high marks on employee surveys
in regard to job satisfaction and communication with management,
among the biggest factors in determining the list.
"I've been aiming for this for 54 years," says Robert
Wegman, the 86-year-old company chairman, who led the company
to $3.4 billion in sales last year. "It's taken a long while
to hit the target, but I finally got there."
At Wegmans' 67 stores in four states, 32,800 workers are paid
hourly wages at the high end of the market and offered a $3-per-week
health insurance premium. The result is a 6 percent annual turnover
rate among full-time employees, compared to 19 percent among
its competitors. "It's hard for me to walk through a store
without customers stopping me and saying, 'You've got a great
store, but, wow, are your people something else,'" says
Wegman.
Editors Note:
Wegmans, a leader in the introduction of irradiated ground beef,
has provided Food Irradiation Update with the following statement:
"Wegmans is a strong believer in the irradiation
process. Although we take every measure to ensure all our
ground beef products are safe, the additional step of irradiation
adds another layer to the food safety chain. Irradiated
ground beef is a value-added product, and we are proud to offer
this alternative to our customers.”

Technology Stock Rises; (December 29, 2004) The Ledger
Online |
|
Speculation that Sunday's tsunami disaster
in South Asia could benefit Food Technology Service Inc. in Mulberry,
Florida sent the company's stock up to $1.55 a share Tuesday,
a one-day jump of 40 percent. The Nasdaq stock, which closed
at $1.11 on Monday, traded as high as $2.70 a share early in
the day on rumors relief agencies might use the company's irradiation
service, said Jim Jones, the vice president of sales and marketing.
The stock may have also benefited by a rumor that cable network
CNBC would air a positive story on irradiation featuring Food
Technology, he said. But no relief agencies or CNBC reporters
have contacted the company yet. Volume soared to nearly 2.8 million
shares from an average of 24,954 shares during the past three
months. Food Technology reported a profit of $46,136 on revenue
of $403,210 for the quarter ending Sept. 30. The company uses
gamma radiation to kill pests and disease-related microorganisms
in food and medical products.

| Cattle linked to common stomach bug (January 11,
2005) New Zealand Herald via FSNET; By Simon Collins: |
|
Cows - New Zealand's main export producers
- have, according to this story, been revealed as unexpected
carriers of the most prevalent stomach bug, campylobacter.
The story notes that the number of food poisoning cases caused
by campylobacter has quadrupled in New Zealand in the past 15
years and is now five times Australia's rate and almost 10 times
that of Canada, and that experts assumed the increase was related
to the growing popularity of chicken, a prime source of the bug.
But an Institute of Environmental Science and Research study,
published quietly by the Ministry of Health two years ago, found
that the biggest risk factor for campylobacter in the rural district
of Ashburton was contact with cows. The story notes that eating
chicken is still believed to be the main cause of campylobacter
in urban areas.
The finding was unearthed during a Herald inquiry into what is
in our food and why New Zealand has the highest food poisoning
rate in the developed world.
The Ashburton study suggests that New Zealand's livestock-based
economy may be a big contributor to these high rates. It
recommends that farmers should:
Stop drinking raw milk taken directly from cows
on the farm.
Stop drinking untreated water.
Wash their hands before eating or smoking after
contact with animals.
Dr Roger Cook, the Food Safety Authority's
principal adviser for food microbiology, was cited as saying
the findings did not threaten New Zealand's dairy and meat exports,
which were processed or frozen.
The FSA has commissioned nine further reports from Environmental
Science and Research to follow up the Ashburton study, including
a discussion document on the main sources of campylobacter, to
be published in March. The authority says contact with animals,
drinking untreated milk and water, and swimming in contaminated
water appears to be "equally, if not more responsible"
than eating chicken and other foods for most cases.
The story notes that the Ashburton study found campylobacter
in 98 per cent of dairy cows' faeces, 84 per cent of beef cattle
faeces, 65 per cent of duck faeces and 60 per cent of sheep faeces.
This meant that farmers who had any contact with animal faeces
needed to be specially careful about washing hands before eating
or smoking. The levels of campylobacter in meat were much
lower.
Dr Cook was further cited as saying that as well as doing further
research on the sources of the bug, Environmental Science and
Research was working on ways of reducing human infection from
chicken, including "crust freezing" techniques which
could kill the bacteria without hardening the texture of the
chicken, adding, "Overseas they have found that if you freeze
the chicken it kills off a lot of the campylobacter. So we are
looking at the effect of refrigeration, both chilled and frozen,
to see if there are some effects that we can use to kill off
campylobacter in chicken."

| Antimicrobial Efficacy of UV radiation on Escherichia
coli O157:H7 (EDL 933) in fruit juices of different absorptivities
(January 2005) |
|
Journal of Food Protection Volume 68, Number
1 p. 49-58 ; Juan M. Oteiza ; Mercedes Peltzer ; Leda Gannuzzi
; AndnoemÌ Zaritzky; http://www.foodprotection.org/QuickLinks.htm
Abstract
The efficacy of UV light for inactivating E. coli (ATCC 25922)
and E. coli O157:H7 (EDL 933) was examined in fruit juices (orange,
apple, and multifruit) with different absorptivities under several
operating conditions (liquid film thickness and agitation rate).
The juices were inoculated with two bacterial concentrations
(105 and 107 CFU/ml) and were treated using a UV disinfection
unit at 254 nm; UV doses ranged from 0 to 6 J/cm2. The effect
of the culture medium, tryptone soy agar (TSA) and sorbitol MacConkey
agar (SMAC), on the recovery of E. coli strains exposed to UV
radiation was also analyzed. The most suitable culture medium
for recovery of E. coli strains in juices exposed to UV radiation
was TSA. Values of D (radiation dose [joules per square centimeter]
necessary to decrease the microbial population by 90%) obtained
in all juices assessed were higher in TSA than in SMAC. In the
juices analyzed, stirring of the medium exposed to UV radiation
and reducing liquid film thickness (to 0.7 mm) produced the highest
bactericidal effect. A linear relationship was found between
the D -values obtained and the absorptivity coefficients for
all the juices. The higher the absorbance of the medium, the
greater the values of D required to inactivate E. coli strains
by UV radiation. An equation was developed to describe the relationship
of the fraction of energy absorbed by the system (absorbed energy
factor [AEF]), the thickness of the film exposed to UV radiation,
and the absorptivity coefficient of the juices. A linear relationship
was found between D and AEF in the different juices tested.
