Generally speaking, it is best not to eat Pipi shrimps that have been dead for more than 2 hours at room temperature. Fresh Pipi shrimps can be kept for 3 hours under natural conditions after being purchased, so consume them as soon as possible during this period.

Pippi shrimps that have been frozen to death in the refrigerator can still be eaten if they smell not stale or spoiled. If they smell strange, don’t eat them to avoid a bad stomach. .

How to buy fresh Pipi shrimp:

1. Look at the color of the shrimp. At a glance, if the color of the shrimp is bright and green, then it is fresh shrimp. If the color is darker and not bright enough, then it is stale shrimp.

2. Look at the shrimp head. If the shrimp head is very weak and looks like it won't fall off, then don't buy it, it's definitely not fresh.

3. Knead it with your hands. If it is high-quality fresh shrimp, the meat will be very firm when pinched.

4. Finally, although it is said that dead Pipi shrimps can be eaten, they are already dead when purchased, so it is best not to buy them.
