USDA BSE Update - Thursday, January 22, 2004

January 22, 2004
From a press release
WASHINGTON -- USDA's investigation into the 81 cattle that came from Canada continues. In total, 23 of the 81 cattle that came from Canada have been located:
* One of the 81 was the positive cow.
* Three have been located at a facility in Tenino, Washington.
* Six have been located at a facility in Connell, Washington.
* One has been located at a dairy in Quincy, Washington.
* Three were at a facility in Mattawa, Washington.
* Nine were in the index herd.
USDA has transported and sampled a total of 39 animals from the Mattawa facility and 131 animals from the index premises. To date, 129 samples from the index herd have completed testing; results were negative. Twenty samples from the Mattawa herd have completed testing; results were negative.
USDA's investigation into 17 additional cattle, mentioned by Dr. Brian Evans, Chief Veterinary Officer for Canada, in the January 6, 2004, technical briefing, continues. These cattle are not part of the original 81 animals. To date, four animals have been traced. Three are located at the Quincy, Washington, facility, and one is at a Boardman, Oregon, facility. The State of Oregon has placed the Boardman facility under a hold order to facilitate the investigation. Investigators are still determining whether the remaining 13 animals entered the United States.
Senior U.S. government officials are continuing talks with trading partners and this week are meeting with officials in Japan, the Philippines, Hong Kong and South Korea to discuss BSE related issues.

Two groups to sue farmed salmon industry
January 23, 2004
Associated Press

SAN FRANCISCO -- The Environmental Working Group and the Center for Environmental Health were cited as filing notice last week of their intent to sue 50 salmon farms, fish processors and grocery chains under a California anti-toxics law.
Michael Green, executive director for the Oakland-based Center for Environmental Health, was quoted as saying, "Our goal is to challenge them to change their practices so their fish is safe to eat."
Alex Trent, executive director of the trade group Salmon of the Americas, was quoted as saying, "(Consumers) will be doing themselves and their families a great disservice if they stop eating farmed salmon," noting that farmed salmon, a source of heart-healthy omega-3 fatty acids, is much cheaper than wild salmon and can be purchased year-round.
The story explains that under Proposition 65, the Safe Drinking Water and Toxic Enforcement Act of 1986, companies are required to notify consumers if their products contain hazardous levels of chemicals known to cause cancer or reproductive harm.
State law requires private groups to first file notice of their intent to sue to give the state attorney general and other prosecutors 60 days to decide whether to join or take over the lawsuit.

BSE-HACCP Issue Clarified
http://www.meatnews.com/index.cfm?fuseaction=Article&artNum=6816
Confusion over altering HACCP plans to be in compliance with new BSE regulations is resolved.

The North American Meat Processors Association, Reston, Virginia, has provided information to processors who are reassessing their HACCP plans regarding the purchase of bone-in beef from cattle less than 30 months of age in accordance with the new regulations designed to keep bovine spongiform encephalopathy out of the U.S. meat supply and restore lost export markets.

NAMP reported that according to USDAs Food Safety and Inspection Service Tech Center in Iowa and its staff field office in Washington, D.C. that a standing letter on file as part of a purchase specification is acceptable for receiving bone in beef order to comply with the new BSE regulations. The letter must state that either:

a) All meat received is from cattle under 30 months of age, or

b) All specific-risk materials according to the FSIS regulations have been removed.

The second option (b) regarding SRMs will probably be much easier to obtain. Again, this can be a standing letter on file, and does not have to come with each load, NAMP emphasize. FSIS is supposedly working on a notice to issue to inspectors for further clarification.

This is different information than we were given by the policy office earlier in the week,?the NAMP release said. And we know there is a lot of confusion in the field.?NAMP advised processors that are having problems with their local inspectors to contact their district office for clarification, or the FSIS Tech Center (Tel: 800) 233-3935).

Agriculture Department Plans Cattle Identification System
(Washington Post, DC)
By Marc Kaufman

The Agriculture Department wants to implement a nationwide cattle identification system as a way to better track the nation's herd after the discovery of the nation's first known case of mad cow disease.

Speaking yesterday before the House Committee on Agriculture, Agriculture Secretary Ann M. Veneman said the department has been studying how to organize a cattle identification system for 18 months and now is looking to speed its implementation.

"I understand the need to get it done quickly," Veneman said. But she also said there is ongoing debate about whether there should be one system organized and perhaps funded by the federal government, or whether the USDA should set standards that cattle ranchers and the meat industry can apply in a variety of ways.

Highlighting the sense of urgency, Veneman said authorities have been able to locate only 24 of the 80 cows that came into the United States with the animal later found to be infected with mad cow disease, or bovine spongiform encephalopathy.

Federal officials want to find those animals because they came from the same dairy herd in Alberta, Canada, as the sick cow and may have eaten the same contaminated food believed to have caused the animal to become infected. With a national identification system, it would be considerably easier to locate individual animals.

The USDA reported yesterday that it had found one more of the animals that came into the United States with the sick cow on a dairy facility in Boardman, Ore., near the Washington border. The farm was placed under quarantine.

Veneman said some meat retailers and restaurant chains such as McDonald's have already begun identification programs of their own. Last fall, she said, McDonald's began paying a higher price for beef that could be traced back to its birth herd.

Veneman's comments came in answer to questions from Rep. Collin C. Peterson (D-Minn.), who said a government-sponsored identification system has been tested and is being used with about 1 million of the nation's 45 million cattle. Peterson said the discovery of mad cow disease in Washington state made it essential to get an identification system into place quickly, and he suggested that the government require ranchers to use the one it helped develop several years ago.

At the hearing, Veneman said that American consumers appear to be taking the mad cow scare in stride, and that "retailers and food service outlets are reporting virtually no adverse effects on consumer demand." She also said that the price of cattle is now about 10 to 15 percent lower than before the contaminated animal was found on Dec. 23, but that prices have been increasing in recent weeks. 1-22-04

BSE Busters

http://www.meatnews.com/index.cfm?fuseaction=Article&artNum=6767

Researchers are investigating methods of destroying the infective agent of bovine spongiform encephalopathy.

U.S. scientist are employing enzymes, heat, pressure, and caustic solutions to destroy the misshapen protein prion that is believed to cause bovine spongiform encephalopathy. Joe Wilson, president of Waste Reduction by Waste Reduction Inc., a Indianapolis, Indiana-headquartered waste reduction technology firm, tells MeatNews.com that USDA has been impressed with the results of his companys system. The Waste Reduction by Waste Reduction treats whole carcasses as well as specific risk material ?spinal cords, brains, intestines, and eyes with sodium hydroxide under 60-65 psi of pressure at 300 degrees F. The company sells equipment that will liquefy a 1,500-pound cow in six to eight hours destroying the prion. have tested this with mice and the infectivity of the material was completely destroyed,?Wilson said. The process leaves behind only about 75 pounds of material that can be safely used as fertilizer. Wilson added that because his process is wet, dust possibly contaminated with BSE is suppressed. The only other alternative is incineration at 1,000 degrees but you still have the risk of spreading the prion in the smoke due to cold spots in the incinerator,?he explained. Wilson predicted that within 10 years SRM treatment and disposal systems will be mandated at all processing plants. He added that the disposal systems dont need to be cost centers. The treated material can be burned as fuel or sold as high-quality fertilizer, The explained. The company manufactures systems that can hold up to 10,000 pounds of material, enough to dissolve several carcasses at once. A digestor that size would cost about $1 million. A large meatpacking plant could generate half a million pounds per day of waste material. Wilson estimated that 30 to 40 digestors are in use in the United States, and at least five are on order for veterinary schools and animal diagnostic centers.

In the meantime, researchers at North Carolina State University are working in cooperation with scientists in the Netherlands to develop enzyme systems that tear apart prions.

Initial studies tested the effects of a bacterial enzyme keratinase on brain tissues from cows with BSE and sheep with scrapie. Results showed that, when the tissue was pretreated and in the presence of a detergent, the enzyme fully degraded the prion, rendering it undetectable. The researchers now plan another study to test the effectiveness of the enzyme on the treated BSE prions in mice. The two-year study begins in January 2004 and is funded with $190,000 from the National Cattlemans Beef Association.

Our work has been done in test tubes, and weve reduced the prion to undetectable levels,?Dr. Jason Shih, one of the North Carolina State University researchers, said. Our work with mice will show whether these undetectable levels of prion are indeed non-infectious.?Shih added that future research will test keratinases effectiveness in decontaminating equipment that processes animal products.

Good bacteria may guard against Salmonella

The Washtington Times
http://www.washtimes.com/upi-breaking/20040119-042632-8030r.htm
FAYETTEVILLE, Ark., Jan. 19 (UPI) -- Arkansas researchers have found several promising intestinal bacteria that may protect poultry from Salmonella and other pathogens. Salmonella, Campylobacter and other pathogens can cause illness in people who eat infected poultry that has not been cooked enough. Pathogens such as Salmonella take hold inside the intestinal tracts of chicken and other birds, however, researchers at Agricultural Research Service in Fayetteville, Ark., and University of Arkansas are getting a better understanding of how probiotics, or live beneficial bacteria, affect the poultry's intestinal tract, Science Daily reported. Probiotics, which can be given orally to poultry, help the birds fight illness and disease by using the concept of competitive exclusion -- probiotics are fed to newly hatched chicks and the probiotics occupy sites in the intestinal tract where the pathogens would normally attach and grow, according to the article in Agricultural Research. Since probiotics are there first, the opportunity for pathogenic bacteria to become established is reduced.

Researchers from the University of Alabama at Birmingham have developed a new DNA-based test that allows for rapid detection of contaminated oysters. Their findings appear in the January 2004 issue of the journal Applied and Environmental Microbiology.

One of the leading causes of seafood-related illnesses in the United States, Vibrio vulnificus, is transmitted by consuming raw or poorly cooked oysters. Infection by V. vulnificus can result in gastroenteritis, septicemia and in many cases death. Due to the extreme number of illnesses reported, the Interstate Shellfish Sanitation Conference has intervened requesting that the number of shellfish-related illnesses be reduced by 60 % by the year 2007.

"In the last two years alone, California has experienced sixteen illnesses resulting in ten deaths, despite educational efforts directed at high-risk populations to warn them of the potential hazards of eating raw oysters."

The new test uses polymerase chain reaction (PCR) to test for the presence of V. vulnificus in as little as eight hours. Current methods require up to three days to confirm contamination.

"Rapid and sensitive detection of V. vulnificus would ensure a steady supply of postharvest treated oysters to consumers, which should help decrease the number of illnesses or outbreaks caused by this pathogen."

Biological weapons sensor detects anthrax in two minutes

A safer and faster way of detecting biological weapons agents has been devised by UK researchers with support from the government's defence research agency.
The optical sensor, developed at UMIST with the help of the Defence Science and Technology Laboratory, is designed to detect changes in antibodies when they come into contact with samples of deadly bacteria such as anthrax. It can also be used to detect bacteria that can lead to food poisoning.
Existing detection devices based on the use of antibodies tend to have low sensitivity - at least 10 million bacteria cells have to be present in 1ml of sample to produce a detectable signal. But levels as low as 10 cells per millilitre can cause infection, making the devices dangerous to use. The UMIST device can operate with a much smaller sample size, said Dr Mohammed Zourob of the university's department of instrumentation and analytical science, who developed the sensor with Dr Nicholas Goddard.
The device, known as a waveguide, is based on a coating of antibodies chosen to target specific bacteria, on to which a light source is shone. When the antibodies come into contact with these bacteria they attack them, changing the way the sensor surface reflects and absorbs light and allowing the germs to be identified.
The waveguide uses a wider field of light than existing sensors, so it can detect changes across the whole sample while existing systems can monitor only certain areas of the surface.
Unlike existing systems the device also uses ultrasound to direct the way the suspect bacteria are deposited, concentrating the sample on the surface and helping to speed up detection, while allowing the cell numbers to be kept small, said Zourob.
'Previously sensors needed 30 minutes [for detection] but our sensor needs two to three minutes or less.'
The device also analyses the reflected light to detect optical scattering effects and fluorescence, which help indicate the type of bacteria present. Existing devices monitor only basic changes in the optical properties of a sensor's surface, and cannot distinguish between benign and malignant bacteria, leading to false alarms.
