1. Slimy Surface on Shrimp
Fresh shrimp is always the top choice when shopping, but sometimes, dead shrimp is still sold and bought. These shrimp are usually the ones that have been processed and preserved, or died shortly after, thus retaining their freshness.
How can you tell if the shrimp is dead but still fresh? A simple way is to observe and touch them. Dead fresh shrimp will have a smooth surface, while non-fresh shrimp will feel slimy.
These non-fresh shrimp are often sold at cheaper prices, and many people buy them thinking that cooking will make them safe to eat. However, you should avoid purchasing these as they may contain bacteria. After cooking and consumption, they might taste delicious, but they could potentially cause harm.
2. Unusual Coloration in Shrimp
Most shrimp are grayish-green or reddish in color, but if you come across shrimp that are white or black, this is certainly abnormal.
White shrimp may have been frozen for too long, losing moisture, and resulting in dry meat. On the other hand, black shrimp indicate deterioration and possible bacterial contamination. Even if they are offered for free, you should refrain from taking them as consuming them could be detrimental to your health.
3. Discolored Heads on Shrimp
Fresh shrimp typically have a uniform color between the head and body. However, if not stored properly, the heads of the shrimp can turn red or black, indicating that they are no longer fresh. It is best to avoid purchasing such shrimp to ensure quality and safeguard your health.
4. Strange Odor from Shrimp
Fresh shrimp, whether alive or dead, usually only have a mild characteristic odor, with hardly any strange smells. If you detect a sour, putrid, or unpleasant stimulating odor, it indicates that the shrimp has deteriorated and may have developed bacteria or been soaked in unsafe preservatives.
These shrimp can be harmful to your health, so it is best to avoid buying them. When selecting shrimp, always pay attention to the smell and quality to ensure the safety of your family’s meals.
