Many diverse species of similar-looking shellfish are referred to as “shrimp.” Cold-water shrimp are tiny shrimp caught in the waters of the United States and Canada’s northwest and northeast areas.

Raw seafood should be avoided by pregnant women and small children, according to the Food and Drug Administration (FDA). Because of their weakened immune systems, they are more susceptible to foodborne infections.

Raw shrimp can carry a variety of dangerous microorganisms that can make people sick.

Vibriosis. The marine bacteria Vibrio (or Vibrio vulnificus) is found in sea organisms. Vibriosis is a disease that it causes in humans. This bacterium can be contracted by eating raw or undercooked fish. However, if a cat comes into touch with raw or undercooked seafood or juices, you can become contaminated.

If you have a minor case of vibriosis, you will most likely feel better in three days. However, 20% of those who contract Vibrio infections die within a few days of becoming ill.

The Following Are Some Of The Symptoms Of This Infection:

Watery diarrhea, sometimes accompanied by stomach cramps, vomiting, nausea, and fever.
Bloodstream infection symptoms include fever, chills, low blood pressure, and blistering skin sores.
Fever, redness, swelling, discharge, discoloration, and pain are all fever symptoms, and these are signs of a wound infection that can spread throughout the body.

Researchers analyzed shrimp purchased from a fish market and discovered that seven out of twenty (35%) shrimp tested positive for Vibrio bacterium. In addition, 100 Vibrio strains have been discovered in farmed shrimp, many of which are antibiotic-resistant.
