Researchers at Kansas State University have developed a
faster test to detect E. coli 0157:H7 in the beef-production and processing
system.
The test involves detecting four genes in the bacteria that
is dangerous to people because it produces poisons that can wipe out kidneys
and can kill.
It was the bacteria involved in the Walkerton water scandal
and in the XL Foods Inc. record-breaking beef recall.
The researchers say the test is not only rapid,
but also less labor-intensive than current detection methods.
The method can also be automated and many
samples can be tested in short order.
"Developing a method to detect E. coli
before it can potentially contaminate the food supply benefits the beef industry
by preventing costly recalls but also benefits the consumer by ensuring the
safety of the beef supply," said Lance Noll, master's student in
veterinary biomedical science.
