It's really hard o, because like a month before I left a friend of mine was caught because she came in with African foods, like meat and so on and they got caught because one of the airport dogs perceived the smell from their box, and all the items were ceased and they still made them paid like 600 Canadian dollars.
But I came in with just little snail, and bush meat, I wrapped it well, sprayed some perf and poured some coffee on it and I packed them in a plastic box. But I was lucky there were no dogs the day I arrived and I didn't declare in the form that I have African foods
