WASHINGTON (KRON) — Parents are advised to avoid microwaving and dishwashing plastic containers as the American Academy of Pediatrics calls for stronger federal food safety regulations. 

In a new report, pediatricians cited growing evidence against chemicals in food colorings, preservatives, and food packaging materials. 

Additionally, heating plastics (including bottles) in the microwave or running them through a dishwasher increases the chance of leaking dangerous chemicals, according to the AAP. 

The report states plastics with recycling codes 3 for phtalates, 6 for styrene, and 7 for bisphenols should be avoided. 

What’s the best container? Officials recommend glass or stainless steel packaging. 

They also suggest avoiding processed food and to remember to wash your hands and produce during food preparation.
