Hey Fellas.

So Ive used food safe Polypropylene tubs in the past as quarantines with no problems.

They are all marked with the food safe symbol, and PP 5.

Today I picked up a couple of tubs to use as froglet growouts and I am in 2 minds as to whether they are safe or not.

They are marked with PP but no 5.

To my knowledge the 5 simply denotes the resin content and whether its recyclable or not.

Ive scoured the internet to find out whether all polypropylene is safe, and if the abscense of the 5 is something to be worried about.

But havent had much luck.

Any info anybody could pass on would be greatly appreciated.
