More
than 80 percent of cases of food poisonings by E. coli 0167:H7 can be traced to
beef and row-crop vegetables, according to a new report from the United States
Department of Agriculture, the U.S. Food
and Drug Administration and the U.S, Centers for Disease Control.
In at least several well-documented cases, the vegetables were contaminated with livestock manure in irrigation water.
The
three agencies gathered and analyzed about 1,000 cases of food poisoning cases
between 1998 and 2012 caused by Salmonella, E. coli O157, Listeria monocytogenes
and Campylobacter.
According
to CDC estimates, these four pathogens cause 1.9 million cases of foodborne
illness in the United States each year.
Almost
three-quarters of Campylobacter illnesses were caused by dairy (66 per cent) or
chicken (eight per cent); 82 per cent of E. coli O157 illnesses were caused by
beef (46 per cent) or vegetables grown in rows (36 per cent), and 81 per cent
of Listeria illnesses were caused by either fruits (50 per cent) or dairy (31
per cent).
With
salmonella, the range was broader, with 77 per cent of illnesses attributed to
vegetables grown from seeds (18 per cent), eggs (12 per cent), fruits (12 per
cent), chicken (10 percent), sprouts (eight percent), beef (nine percent), and
pork (eight percent).
I find the sprouts statistic hard to believe because they have so often caused major outbreaks of food poisoning.
Dr.
Chris Braden of CDC’s Division of Foodborne, Waterborne and Environmental
Diseases, said a single methodology allows agencies to better coordinate their
efforts.
"We
can do more as a group than we can individually."
His
comments are in the context of a proposal from President Barack Obama to have a
single agency responsible for food safety.
