Best Hoodia GordoniiSubject: Food Poisoning From Meat

Animals farmed for meat are the No. 1 source of food poisoning bug,
study shows
A study by researchers from Lancashire, England, and Chicago, IL,
found that 97 percent of campylobacteriosis cases sampled in
Lancashire were caused by bacteria typically found in chicken and
livestock. The work, which appears September 26 in the open-access
journal PLoS Genetics, is based on DNA-sequence comparison of
thousands of bacteria collected from human patients and animal
carriers.
Campylobacter jejuni causes more cases of gastroenteritis in the
developed world than any other bacterial pathogen, including E. coli,
Salmonella, Clostridium and Listeria combined. Wild and domestic
animals act as natural reservoirs for the disease, which can also
survive in water and soil. However, the relative importance of these
sources is unclear, and recent work has suggested that livestock are
not the main reservoir for human disease.
Researchers led by Daniel Wilson, of the University of Chicago, and
formerly Lancaster University, United Kingdom, sequenced the DNA of
bacteria collected from 1,231 patients and compared it to
Campylobacter jejuni DNA sequences collected from wild and domestic
animals, and the environment. They used evolutionary modeling to trace
the ancestry of human C. jejuni back to one of seven source
populations.
In 57 percent of cases, the bacteria could be traced to chicken, and
in 35 percent to cattle. Wild animal and environmental sources were
accountable for just three percent of disease.
"The dual observations that livestock are a frequent source of human
disease isolates and that wild animals and the environment are not,
strongly support the notion that preparation or consumption of
infected meat and poultry is the dominant transmission route," Wilson
said.
Further studies are underway in the United States, the United Kingdom
and New Zealand to determine the generality of the result. But the
authors say they hope the current study will add impetus to
initiatives aimed at controlling food-borne pathogens.
