I have never had shark meat before so when I saw some pre cooked marinated chunks on special at the store last night, I bought some. Now that I am researching shark meat online, I am reluctant to eat it. If the shark is not killed, bled and gutted immediately, the meat will have high concentrations of uric acid and will be toxic (kind of reminds me of blowfish). What bothers me was that it was marinated. Was it bad meat that was marinated to cover up the ammonia smell? I normally have a good sense of smell and taste but not having eaten shark before, and it being marinated, I am not so sure. I only paid $2 for it so I would not really be out a lot of money by tossing it. Not worth getting sick over.
