IFR research scientist Mark Reuter said the
research had shown campylobacter to be very intelligent and able to move
towards environments in which it knows it can survive.
The
pathogen is smarter than we thought, and cannot be underestimated. It has the
ability to recognize its environment and modify its movement in response to
move to where it wants to be, It will also change its behavior and swim away
from things it proven dangerous.
Campylobacter
balances information it receives either to seek locations that provide it with
more nutrition, or to find places where respiration is more efficient. The
desire to feed, however, is the biggest driver for campylobacter, the research
found.
Undercooked poultry: When people get infected, the bacteria need to find their
way from the source of contamination, usually undercooked poultry, to the cells
lining the gut. In the process, campylobacter must find enough food to sustain
it as well as a hospitable environment in which to multiply. Unlike other food
poisoning pathogens, such as E. coli
or Salmonella, campylobacter have a
whole range of ways of detecting different chemicals in their immediate environment,
and can alter the way they move through the body.
Foodborne pathogens: Campylobacter has the
ability to sense if the host body is hungry and will move towards the gut in
preparation for new food on which to latch. Chicken is responsible for 60–80% of
cases of the infection campylobacteriosis in the UK. Campylobacter jejuni is the major cause of food poisoning in the
UK, with over 371,000 incidents a year. It is a top priority for the Food
Standards Agency (FSA), which aims to reduce cases by 10% by 2015.
The
new research from the IFR was welcomed by the FSA. A spokesman said it would
help to improve the understanding of campylobacter in the food chain and how it
might be controlled. This is important in informing the FSA’s strategy, which
is currently focused on reducing the contamination of poultry carcasses with Campylobacter.
A
10% reduction is possible because other countries have done it. This research
gives a new personality to the pathogen, and needs to be taken on board by the
industry. Manufacturers should look at what they can do to prevent the spread
of campylobacter, not just look to scientists for a magic bullet against Campylobacter jejuni.
