I think that most types of farm raised shrimp should be avoided by consumers because of all of the problems that re addressed in this article. The bottom line is that whether you like to eat shrimp, beef, chicken, or other types of seafood, the best varieties are either caught wild from their natural environments or raised in settings that mimic their natural environments.
A good way to avoid farm raised shrimp is to look for the word sustainable on the packaging. Most products that carry this label are produced with the environment and consumer well-being in mind. They are also free of the harmful by-products of raising animals for consumption in man-made settings.
