Scientists develop new test for BSE risk materials
Florida State University | Updated: 04/10/2013
A new screening method to detect tissues associated with Bovine Spongiform
Encephalopathy (BSE) in processed food will be developed through a new license
agreement between Florida State University and Gainesville-based ELISA
Technologies.
Invented by Peggy Hsieh, a food scientist and the Betty M. Watts professor
in FSU’s Department of Nutrition, Food and Exercise Sciences, the screening
method uses a novel monoclonal antibody to detect the presence of bovine central
nervous system (CNS) tissue in processed food and animal feed products.
Consumption of foods containing infected bovine CNS tissue is believed to be the
main cause of the extremely rare transmission of the disease to humans. The U.S.
Food and Drug Administration has banned this risk-related material in human food
since 2004, and in animal feed since 2009.
“While we have been lucky enough to have avoided any recent outbreaks of
this deadly disease, it remains a serious concern both here in the U.S. and
especially overseas in Europe,” Hsieh said. “This new test kit aims to address
some of those concerns by providing a low-cost, accurate screening method that
would allow for the routine testing of heat-processed foods and feed
products.”
The main advantage of Hsieh’s new testing kit is the ability of the
antibody to detect the presence of CNS tissue even after the food has been
exposed to high levels of heat. Currently, there are no useful testing methods
for food that has been heat processed, creating potential situations where
contaminated tissue could slip though established detection protocols. Hsieh’s
invention also will be important in the testing of animal feed products in order
to prevent the introduction of disease contaminated CNS tissue into animal
populations.
Laura Allred, president of ELISA Technologies, reports that “the antibody
developed by Dr. Hsieh is incredibly sensitive and robust, creating an assay
that can detect as little as 2 parts per million (ppm) of the target protein.
This method will be a valuable tool for industry and regulators.”
“Dr. Hsieh has developed an impressive reputation for her work in the areas
of food safety and quality, and I commend her efforts to transform her work into
market-viable products,” said Gary K. Ostrander, vice president for Research.
“This type of commercialization is a great example of the economic value of
university-based research and the immediate benefit it can bring to the
public.”

Final Feed Investigation Summary - California BSE Case - July 2012
What irks many scientists is the USDA’s April 25 statement that the rare
disease is “not generally associated with an animal consuming infected feed.”
The USDA’s conclusion is a “gross oversimplification,” said Dr. Paul Brown,
one of the world’s experts on this type of disease who retired recently from the
National Institutes of Health.
"(The agency) has no foundation on which to base that statement.”
“We can’t say it’s not feed related,” agreed Dr. Linda Detwiler, an
official with the USDA during the Clinton Administration now at Mississippi
State.
In the May 1 email to me, USDA’s Cole backed off a bit. “No one knows the
origins of atypical cases of BSE,” she said
