Faster Campylobacter screener developed
Campylobacter infection is a worldwide public
health concern and is the leading cause of enteric illness in many countries.
With about 50,000 human cases of illness per year, campylobacter is the most
common known cause of food borne infection contracted inUK.
regulatory standards and more stringent testing cause delays in products hitting
the shelves and so processors are constantly searching for faster methods to
test food safety.
A new campylobacter
testing system, developed by DuPont, can reduce result times from days to
hours, compared to traditional methods, the manufacturer claims.
The new real-time campylobacter assay can produce results within two
and a half hours for contaminated samples, and within two days for those
requiring enrichment, the manufacturer claims. Most current screening procedures
for campylobacter are culture-based, take at least three days for a result and
do not differentiate between species without additional investigational work.
The new assay also allows differentiation between the pathogenic species C.
jejuni, C. coli and C. lari, and quantification of three campylobacter
DuPont Qualicon BAX system targets specific probes by
measuring fluorescence. The BAX system is simple and testing is straight-forward
and requires no additional equipment, the manufacturer claims.
A representative for the company said that the Food Standards Agency
strategic plan for 2005 - 2010 includes a commitment â€œto work with the industry
to achieve a 50 per cent reduction in the incidence of UK produced chickens
which test positive for campylobacter by 2010."
