SAN FRANCISCO, CA (KRON) – Two-thirds of baby food in the United States has tested positive for arsenic and other dangerous toxins, according to a new study.

Some of the most popular baby foods on the market tested positive for the toxins.

Five-hundred baby food products were tested.

The study by the Clean Label Project also found that a whopping 80 percent of baby formulas contained arsenic.

Experts warn that arsenic can affect a child’s motor skills, cognition, and heart as they’re growing.

Also in that study is lead. More than a third of the popular baby foods tested positive for lead.

And nearly 60 percent contained another metal-cadmium.

Those chemicals can pose potential risks for infants especially problems with their young immune and nervous systems.

The FDA had previously looked into the impact of arsenic in rice-based baby foods and even rice puffs.

Health experts say the best thing a parent can do is look closely at the food labels.
