I just use Brute trash cans. I know the grey ones are food safe... come of the colors actually aren't.
Plus with the optional wheels they're pretty convenient & mobile
Wash with a vinegar solution, then rinse well, and almost any plastic bin will work.
The main concern is chemicals on the plastic from manufacturing or shipment.
I have used Brute trash cans, black bins above, and blue rubbermaid bins.
