How to Tell if Shrimp is Bad?
Before cooking shrimp, you need to check its appearance and smell. A bad-smelling shrimp may have a slimy texture or a sour smell. Regardless of color, it should be white, slightly transparent, or pink. If the shells are discolored, it’s probably spoiled, and the shrimp were likely treated with a bleaching chemical if the shells were brown. Moreover, a rancid shrimp may have an unpleasant flavor.
Fresh raw shrimp is whitish-gray and slightly translucent. A bad one will have black spots and a slimy texture. Besides, spoiled shrimp will have a slimy, moldy, or faded appearance.
