" It reduces test and hold time for meat and
poultry products to hours, instead of days, "
Hogan pointed out. " It's AOAC-approved and
comes in six formulations: E. coli, Listeria,
Salmonella and E. coli, STEC and mTSB.
" We can do Listeria in four hours;
Salmonella in 10 hours; and E. coli in six hours
for enrichment to take place. "
Once the enrichment is done, processors
use a PCR reader to find out if there are any
foodborne pathogens in the products.
" In 15 or 20 minutes, you can have sterilized
enrichment media, " he noted. " And we're
looking for ways to make it even faster. "
There are two phases for achieving food
safety: enrichment and then reading, with
PCR. The enrichment phase is critical, Hogan
explained, because chemicals must be mixed
to create enrichment media.
" For Listeria, for example, we mix 11
chemicals to make our media. Rapid testing is
certainly an improvement over doing cultures,
which can take four or five days. And the
PCR is just as accurate. And if
our media is being used, it's even
faster, " Hogan said.

is presumptive - there still needs to be culture
reading to ensure what the testing shows. "
She also pointed out that processors must
go beyond pathogen testing for food products
to carry out their food safety responsibilities.
HACCP food safety plans are required, as are
good manufacturing practices and sanitation
standard operating procedures.
A major advance in pathogen testing
is the shift from qualitative analysis to
quantitative analysis.
" Traditionally, testing for pathogens in
meat and poultry sought to find if any target
pathogens, like Salmonella, Listeria, E. coli
O157:H7 or Campylobacter were present, and
if so, which ones, " she said. " But now, USDA
has become much more interested in the
quantity of pathogens - how many might be
present. By enumerating the pathogens, that
gives the company a much better idea of the
safety of its products. It also measures the
virulence of the pathogens - how harmful and
severe they are to consumers. "

" Rapid testing
technology
shaves days
off the time
traditional
methods take. "

SPEED BENEFITS
Rapid testing technology for
foodborne pathogens for meat
and poultry processors allows test
results to be known by processors
and slaughterers much quicker,
opening the way for them to move
their products to the markets.
That way, they aren't stuck holding
products for long periods of
time, which can affect both the
freshness of products and their
busines operations.
" With rapid testing, we can
have presumptive results and
confirmation of those results,
as fast as seven to 10 hours, "
explained Season Xie, meat and
poultry applications scientist
for Bio-Rad Laboratories Food
Science Division in Hercules, Calif.
" Carrying out test-and-hold
requirements can be especially
difficult when products have a
relatively short shelf life, " she
noted. " And the rapid-testing result
