This plastics safe for these purposes?

The ones in the top part of the photo I was thinking of using to house small terrestrial species. The bottom one to be used to feed newts/aquatics in. To avoid fouling the tank, I would place the newts in these and feed them there, each enclosure would have its own set of containers to prevent cross-contamination. Would these plastic containers be safe to use for these purposes?

I've used similar tubs for fish and herps in the past, none identical to those but lots of different ones over the years and never had a problem. If they are food grade then I'm pretty sure they're safe.

I personally would not remove animals from their tank to feed in a separate container. I would be concerned about causing the animal excessive stress by doing so.

But for instance with fire bellies, if I just dump in bloodworms won't some bully the food away from the others, and I have seen paddletails attack one another during feedings, and won't it make too much waste for partial water changes to handle?

Paddletails will attack each other when they're not feeding!
I think only the boldest species will feed outside their home environment, especially aquatic ones. Maybe axolotls would or Ribbed newts? My fire bellies are spoilt rotten and extremely tame but there's no way they would be happy being fed if I dumped them out their tank 1st. I was thinking more about the safety of the plastic rather than what it was being used for.
