and sanitary; using sanitary dressing procedures in the plant; and utilizing
appropriate intervention technologies.
"For E. coli O157:H7 and the other E. coli STECs, these technologies
include hot water pasteurization, hot water wash cabinets, chilling to get
the carcasses cold before pathogen growth begins. And we're working on
new application technologies as well," Owens says.
The discovery of more pathogenic E. coli and increased foodborne
illnesses in non-meat products creates new challenges. "With meat,
there's often a cooking step that can help. But with produce, vegetables,
cheeses, the products are often consumed raw. That makes it more
difficult," he says.

Mike Clark, International Group Manager, PCR Food, at Bio-Rad
Laboratories, Hercules, California, is an expert on innovative technologies
that can be used to detect the presence of pathogenic E. coli. "PCR,
polymerase chain reaction, is used in molecular biology to detect the
presence or absence of a gene to identify the presence of pathogens," he
says. "Our expertise is PCR."
Clark says new technology, including dd (droplet digital) PCR shows
promise. This detection technology determines whether "virulent markers"
that show the presence of a pathogen are present in meat cells.
"With real time PCR, you get next-day results, which is good when
you're facing time pressure while holding products," Clark says. "You
also reduce the number of false positives. But you don't know if it's
present in one bacteria or another. With ddPCR, you can find out if both
virulent markers are present in one cell, which is what you need to prove
a positive," he says. "The process uses a water-oil emulsion system and
creates vast numbers of samples within a single sample. There's much
more accuracy and the sampling is done much quicker." He says the new
ddPCR testing method is going to be offered by Bio-Rad commercially.
"We also offer rapid chromogenic media using cost-effective laborsaving protocols to detect and enumerate microorganisms with a shorter
time to results than 'classical' methods, like culture detection. Cultures
from food sources are grown on plates and examined for pathogens like E.
coli. While this is the time-tested method of detection, it's also very slow.
It can take days and days, so that's why we're moving to faster methods,"
Clark says.
