Let’s be honest – nobody likes thinking about parasites in their food. But as someone who’s spent years researching and writing about seafood safety, I believe it’s important to address this squeamish but crucial topic head-on. Yes, shrimp can contain parasites, but don’t let that stop you from enjoying this delicious seafood! With proper handling and cooking, you can safely enjoy shrimp without worry.
The Truth About Parasites in Shrimp
Like most seafood, both wild-caught and farmed shrimp can harbor various parasites. Studies show that up to 70% of wild-caught shrimp may contain some form of parasitic organisms. Common parasites found in shrimp include:
- Nematodes (roundworms)
- Cestodes (tapeworms)
- Copepods
- Amphipods
- Microsporidians
- Gregarines
These little freeloaders typically attach themselves to:
- The shrimp’s body
- Muscle tissue
- Digestive organs
How Do Shrimp Get Parasites?
Shrimp can become infected with parasites through several routes:
- Contaminated water
- Infected food sources (plankton, algae, smaller crustaceans)
- Skin lesions or openings
- Poor water quality in farming conditions
- Overcrowding in shrimp farms
Warning Signs to Watch For
When buying shrimp keep an eye out for these visible signs of parasitic infection
- Lesions or wounds on the body
- Reddish or blueish skin discoloration
- Small white spots on the shell
- Swelling of digestive organs
- Abnormal swimming patterns
- Protruding eggs or larvae
Are Farm-Raised vs Wild-Caught Shrimp Different?
Here’s something interesting – farmed shrimp actually tend to have MORE parasites than wild-caught ones! This is mainly due to:
- Crowded farming conditions
- Limited space
- Easier spread of pathogens
- Stress on the shrimp’s immune system

- Keep refrigerated below 40°F (4°C)
- Use separate cutting boards for raw shrimp
- Wash hands thoroughly before and after handling
- Don’t leave raw shrimp at room temperature over 2 hours

How to prepare shrimp safely
Raw shrimp should not be eaten because the risk of food poisoning is very high. Therefore, shrimp should be cooked to eat them most safely.
Because improper harvesting, handling, and storage techniques can increase the risk of contamination, you should buy high-quality shrimp from a reputable source. Look for production facilities that are certified in food safety when choosing.
Fresh shrimp should be refrigerated and consumed within four days or frozen for up to five months.
The safest way to thaw frozen shrimp is to remove them from their packaging and store them in the refrigerator overnight or for up to 24 hours. This will minimize the spread of harmful bacteria.
To prepare, wash your shrimp thoroughly, as any dirt can hide bacteria, and make sure other foods are at a safe distance to prevent cross-contamination.
While such techniques may reduce the growth of some harmful bacteria, they will not kill all of the bacteria present. So even if you prepare them carefully, raw shrimp still pose a health risk.
Instead, you should cook shrimp until they are opaque or pink or have reached an internal temperature of 145 0 F (63 °C). Most harmful bacteria and viruses will be killed during cooking.

Potential risks of eating raw shrimp
Each year, 16.7% of Americans experience food poisoning. Eating raw shrimp increases the risk of food poisoning and is one of the causes of the above food poisoning.
May contain harmful bacteria
Vibrio is a type of bacteria found in 70 species, of which 12 are known to cause disease in humans. Vibrio is a bacteria that often lives on shrimp. One study found that 55% of 299 raw shrimp samples contained potentially harmful Vibrio species that can cause conditions such as gastritis, cholera, and infection. If you have a mild case of Vibriosis, you will probably recover in about three days. But 20% of people infected with Vibrio bacteria die, sometimes within a few days of getting sick. Symptoms of this infection include:
- Diarrhea, often with abdominal pain, vomiting, nausea, fever,
- Fever, chills, low blood pressure, and blistering skin lesions, signs of sepsis.
- Fever, redness, swelling, discharge, discoloration, and pain. These are symptoms of a wound infection that can spread to the rest of the body.
In addition, one study found multiple antibiotic-resistant strains of Vibrio bacteria among 100 strains of Vibrio bacteria isolated.
In a review of 10 seafood processing plants in Nigeria, 100% of shrimp contained Bacillus bacteria, which is commonly associated with diarrhea and vomiting.
Can lead to illness
Food poisoning is a common illness associated with eating food contaminated with bacteria. Symptoms can include vomiting, stomach cramps, fever and diarrhoea.
Food poisoning statistics show that more than 90% of food poisoning cases are caused by Salmonella, E. coli, Vibrio or Bacillus, all of which can be found parasitically in raw shrimp. Norovirus can also be found in raw shrimp.
Every year, about 1 billion cases of food poisoning related to diarrhea occur worldwide. In the United States, more than 5,000 people die each year from food poisoning-related illnesses. Elderly people, pregnant women, and children should especially avoid eating raw or undercooked shrimp, as their immune systems are not yet fully developed or have problems.
