Sen. Chuck Schumer on Sunday demanded a federal probe into “very troubling” reports that baby food products are contaminated with lead and other toxic heavy metals.

The New York lawmaker said the Food and Drug Administration must respond to a study that found 95 percent of 168 baby foods tested contained heavy metals, which can affect brain development.

“The report is very, very troubling,” Schumer said outside infant-goods store BuyBuy Baby in Chelsea. “Now, we all know how bad lead can hurt a toddler, but when it’s a little baby it’s even worse.”

One in four baby foods was found to contain lead, arsenic, mercury and cadmium, according to the report Thursday.

“When these toxic metals get into a baby’s nervous system, it can retard brain development, nerve development, the very kind of things we’ve seen [with] lead,” Schumer said.

The senate’s top Democrat called on the FDA to develop a proactive testing program for baby food, as well as establish standards for heavy metals to protect against neuro-developmental issues.

“Parents across the land should worry about teaching their children the ABCs, not worry about what’s in their baby’s food, but now they have to worry because we’re sitting on our hands,” he said.

The latest health challenge comes during a months-long search for the job of FDA commissioner. The Trump administration hasn’t nominated anyone to the post since the agency’s former commissioner, Scott Gottlieb, stepped down in April.

“They can’t do the job they should be doing,” Schumer said, adding that the regulation is “worse than it’s ever been.”

The FDA responded to a call for a probe Monday in a statement.

“The FDA is committed to helping ensure the safety of foods in the U.S., particularly those eaten by our most vulnerable populations, like infants and children,” the FDA said. “Our work includes actively monitoring levels of arsenic, lead and other elements, which occur naturally in some foods, and working to identify the most effective and feasible ways to reduce exposure to these elements from food.”

“While we have seen progress in this area, more work can be done to further decrease exposures to these elements from foods. The FDA is committed to working with stakeholders in industry and in advocacy, to continue to reduce exposure to these elements. Our recommendation, and that of the American Academy of Pediatrics, is that parents continue to feed their babies and children an age appropriate, varied, well balanced diet for nutrition and food safety.”
