Ha, if the FDA says it’s safe then it’s probably not. Here’s a measuring stick should a infant be allowed to play and chew on cured epoxy.
Its ok for other people’s children is not a answer
Bars, restaurants, cafeterias, food processors, food warehouses,,,,,etc....virtually anywhere that serves, processes, stores food items and has surfaces that need some sort of extremely washable coatings will have to use a product on the FDA approved list.
It has nothing to do with children per se.

Then there's potable water & the need for tank linings. Coal tar epoxies are used there.

I don't consider their opinion for what's safe and not safe.
It's not really their opinion. There's a very rigid set of tests a product has to pass in order to be approved.
Anyhow - I can 100% guarantee you that you are either eating or drinking something which has been in contact with some sort of paint or coating every day of your life. From the water you drink to the beer that you drink(beer cans are lined with a coating) to the meat on your table - everything has been in contact with some sort of painted or coated surface.
Believe me - I despise big government more than anyone, but, some things do need someone to lay down & enforce some set of guidelines.
