Food Researchers Find Butter Contaminated With Fire Retardant

The pat of butter you put on your toast may be a hazard to more than your waistline.

Researchers looking into the amount of organic pollutants in food discovered an unexpectedly large amount of the flame retardant PBDE in one of 10 samples of butter bought at stores in Dallas, Tex. Smaller amounts of the substance were found in the nine other samples.

The Philadelphia Inquirer noted that the study,  published in the journal Environmental Health Perspectives,  was limited and the amounts of flame retardant were small enough to be measured in trillionths of a gram per gram of butter. Still, the lead researcher, Arnold Schecter, said the concentration found in the worst sample — amounting to about 135 times more PBDE than in the other samples — demonstrated the need for a broad federal food-testing program.

“This is a brominated flame retardant. It should not be in butter at all,” said Schecter, an expert in environmental and occupational health at the University of Texas.

The source of the PBDE – short for polybrominated diphenyl ethers – appeared to be the wrapper, the researchers said.

According to Food Quality News, the flame retardant is widely used in electronics and textiles, wire and cable insulation, and automobile and airplane components. One of the PBDE compounds found at particularly high levels in the tainted butter, known as deca-BDE, is scheduled to be phased out by U.S. manufacturers by 2014 because of its toxicity to humans and animals.
