The compostable bowls you get at restaurants like Chipotle are made with a chemical the EPA says cause cancer.
The "New Food Economy" just published an investigation.
It tested fiber bowls from eight different restaurants in New York City.
The investigation found "Fluorine" in those dishes and says it's a sign the bowls were treated with 'Forever Chemicals'.
"New food economy" says the chemicals help the bowls hold up to hot, greasy food.
According to the EPA those chemicals cause cancer and reproductive and developmental issues.
