A warning issued to parents of newborns says the food they're feeding their babies may not be safe to eat.
The report from the non-profit Environment Defense Fund found that about 20 percent of baby food samples tested over an 11 year peiod contained detectable levels of lead.
CNN reports the lead was most commonly found in fruit juices (89%), root vegetable foods (86%) and teething biscuits (47%).
No baby food brands among the 2,164 samples collected between 2003 and 2013 were identified in the study.
The levels of lead are still considered to be low, but the CDC says that no safe blood lead level has been identified in children.
In a Chicago Tribune report, the CDC claims "even low levels of lead in blood have been shown to affect IQ, ability to pay attention, and academic achievement. And effects of lead exposure cannot be corrected."
If parents are worried, pediatricians suggest home-made alternatives to store-bought brands, and cutting back on the daily juice intake of children.
