Any seafood items must be certified organic, chemical free.
(Much like your concern with the Wal Mart worms)
Frozen seafood is commonly treated with a nasty chemical called SodiumTripolyPhosphate, the same chemical used in dish detergents, laundry soap and car washing fluid.
That's right, I won't even eat that rubbish.
The abbreviation for this chemical is STPP, it's listed right on the bag.
Too bad, I can get a huge bag of shrimp at Wal Mart for $5, but it causes organ damage in reptiles. Soooo I am forced to buy the $13 per pound organic stuff.
Phosphates in food!
I have lost a few reptiles over this in the past, and it's a horrible way to die.
I agree, ask all you want, it's for the best.
