Study finding toxins in baby food questioned

A study that found 95 percent of baby food sold in the United States contains traces of heavy metals that could harm infants' brain development has come under fire from organic products and rice trade groups.

The research by Healthy Babies Bright Futures, or HBBF, an alliance of scientists and child safety advocates, tested 168 products from 61 brands for arsenic, lead, cadmium and mercury.

It found that 95 percent of the products contained lead, 73 percent contained arsenic, 32 percent contained cadmium and 32 percent contained mercury. At least 25 percent of all the baby food tested from major retailers contained all four, according to the study.
