Are shrimp bad if they smell fishy?
Similarly, why does my shrimp smell fishy?
As with any type of seafood, shrimp's odor becomes more pronounced the longer it is out of the water. While a slight iodine odor or fishy smell is normal, a strong smell might indicate your shrimp is no longer safe to eat. After cooking, your house might reek of shrimp, but there are ways to combat that.
Consequently, how do you know if shrimp has gone bad?
The best way is to smell and look at the shrimp: signs of bad shrimp are a sour smell, dull color and slimy texture; discard any shrimp with an off smell or appearance.
After testing them for bacteria and antibiotics, almost 20% of the ready-to-eat kind were ridden with the bad stuff. Those bacteria can potentially cause illnesses such as food poisoning—which could include diarrhea and dehydration—and, in rare instances, can even prove fatal. As for raw shrimp, it gets worse.
