I ate meal worms, crickets and even a large cockroach at a fair once. These two guys that owned the stall were saying how world hunger could end if more people ate insects. Sounds like nonsense personally, but anyways.
The cockroach was disgusting. I bit into it and there was a crunch then I was spitting wings and legs out, they were all dried out and pretty tasteless. I never kept insects at the time and I sure wouldn't have eaten crickets if I had known they were so smelly and dirty.
The thought of parasites wouldn't put me off though as the cooking process will kill anything off. Cattle, sheep and game carry loads of parasites. The meat is fine once its cooked.
I often eat snails and all types of shellfish found in and around my local sea shores. which are just big bugs that live in the sea. never found the ones at the fair appetising, but I could go for a bowl of that rice in picture right now.
