Fire retardant in peanut butter?

A new study may make some people think twice about today's lunch.{}It could contain flame retardant.{}Researchers sampled 36 foods, including peanut butter, from Dallas-area stores between 2009 and 2010. {}The study's author is from the University of Texas School of Public Health. {}The scientists say nearly half of their samples had detectable levels of HBCD.{}That's a commercial flame retardant mixture.{}{}

They also sampled other foods, like deli meat, poultry, and sardines.{}Researchers say food could be behind elevated HBCD levels in humans and that the data suggests a larger and more representative sampling should be done.{}

The study is in a peer-reviewed journal published by the National Institute of Environmental Health, called "Environmental Health Perspectives."{}
