The truth is, there is simply a lot of danger involved in eating seafood. It's full of bacteria, mercury, chemicals, and the industry is overwrought with environmental destruction and human rights violations. The Old Testament forbids the consumption of pork and shellfish. Well...there's probably a good reason for that according to health sources including Dherbs.com, distributor of various body cleanse supplements:
"Shrimp is a scavenger that thrives off of eating the flesh of dead creatures.
If you eat shrimp, you should be aware that you might be eating feces as well. The dark-colored tube on the shrimps back is the intestinal tract of the shrimp and it harbors bacteria. If you enjoy eating shrimp, you should remove the intestinal tube by running a small pick down the back of the shrimp until the tube falls out."
According to Greenpeace, tropical shrimp farming is harmful to the environment as well. And our grocers aren't doing an excellent job of keeping toxic fish and other seafood off of our plates either. I was dismayed to realize that Kroger barely escaped Greenpeace's fail grade because of "red listed" seafood. The red list primarily addresses seafood sustainability. But what about health?
