Mad cow disease has some consumers worried about what might be in their beef—but
what about a harmful substance we already know is inside chicken? As
this ScienCentral news video reports, there's new information out on the amount
of arsenic in chicken.
Poison in Your Poultry
Chicken is a big part of the American diet, and
is increasing. So it's important to know what's in this popular poultry.
Small amounts of the poison arsenic
are commonly added to chicken feed as an approved supplement that controls
intestinal parasites. While the amount passed on to the majority of people
who eat chicken is not high enough to be harmful,
report in the journal Environmental
Health Perspectives shows that arsenic exposure from chicken is much
higher than previously thought.
"When we looked at the arsenic levels, we noticed that the levels were
three or four times higher in chickens than in other poultry and meats,"
Lasky, an epidemiologist who completed the study while working for the
United States Department of
Agriculture (USDA). (Lasky now works for the National
Institutes of Health.)
