What it is

A phenolic compound used to make polycarbonate plastics and epoxy can linings.

What it does

Building block for hard clear plastics (bottles, containers) and internal coating of metal food cans.

Why it’s a concern

EFSA set a tolerable daily intake of 0.2 ng/kg body weight per day in 2023, based principally on an immune endpoint in mice. That precautionary limit is not a proven human-disease boundary. FDA has not adopted it and continues to consider currently approved US food-contact uses safe. NHANES 2013-2014 detected BPA in 95.7% of tested US urine samples, which shows recent exposure rather than harm.
