Will I Get Sick From Eating Undercooked Shrimp?

Some individuals think that consuming a raw shrimp can make you sick. Vibrio parahaemolyticus, a bacteria that can cause diarrhea, nausea, and vomiting, may be present in raw shrimp.

Abdominal cramps, a fever, and chills are some other signs of food poisoning from raw shrimp. After eating raw shrimp, you should seek medical assistance right away if you have any of these symptoms.

Additionally, it’s crucial to remember that pregnant women shouldn’t consume raw shrimp because it can contain dangerous bacteria that could seriously affect both the mother and the unborn child. It is advisable not to eat any raw shrimp if you are pregnant or intend to get pregnant.

Foodborne Illnesses and Shrimp

Pregnant women and small children should avoid eating raw seafood, according to the Food and Drug Administration (FDA). They are more susceptible to foodborne infections due to their weakened immune systems.

Several types of dangerous bacteria that can make people sick are present in raw shrimp.


Vibriosis. A marine bacteria called Vibrio (or Vibrio vulnificus) is present in sea life. Vibriosis, a disease that affects people, is caused by it. If you consume seafood that is raw or undercooked, you could become ill. However, if raw or undercooked seafood or its juices come into touch with a cut, you could potentially become infected. A

If you contract a mild case of vibriosis, you’ll probably feel better in three days or so. However, 20% of those who have a Vibrio infection pass away, sometimes just a few days after becoming ill.

The following are signs of this infection:

  • Watery diarrhea, frequently accompanied with nausea, vomiting, stomach cramps, and fever A
  • Pain, redness, swelling, discharge, fever, and other symptoms. These are wound infection symptoms that could spread to other parts of the body.

When shrimp from a fish market were analyzed, researchers discovered that 7 out of 20 (35% of the shrimp) tested positive for Vibrio bacteria. And 100 different Vibrio strains, many of which are antibiotic-resistant, have been discovered in farmed shrimp. a


Diarrhea is a symptom of cholera, an intestinal infection. Cholera can be acquired through the consumption of infected food or water. It can also spread if seafood is eaten uncooked or undercooked. A

Shrimp, crabs, and other shellfish have a protective shell around them that the cholera-causing Vibrio cholerae bacteria can adhere to. Although cholera is uncommon in the United States, it is a serious infection in many other countries.

In 33% of the samples tested in a study of a significant shrimp-producing region in Thailand, researchers discovered Vibrio cholerae non-O1. This virus has been linked to episodes of stomach flu or gastroenteritis.

Parasites. Like all other living things, shrimp are susceptible to parasites. These microorganisms, which require a host to survive, can be found in raw or lightly preserved seafood dishes like sashimi, sushi, and ceviche. For this reason, restaurants produce sashimi and sushi using seafood that has been professionally frozen.

Here are FDA recommendations for how long fish should be kept chilled after being marketed for consumption raw:

  • -4F (-20C) or lower for a week. A
  • -31°F (-35°C) or lower until solid, then kept there for 15 hours.
  • -4F (-20C) for 24 hours after being stored at -31F (-35C) or lower until solid.

If you choose to consume raw shrimp, make sure you only do so from establishments with a solid reputation for hygiene and safety. However, groups that are concerned with food safety generally advise that you cook your seafood. A temperature of 145F should be reached while cooking the majority of seafood (63C). A

The smell of rotten raw seafood may be sour, rancid, or ammonia-like. These odors intensify when cooking. Seafood that has these smells shouldn’t be consumed raw or cooked. A

could result in disease

A frequent condition linked to eating foods contaminated with bacteria is food poisoning. Symptoms may include diarrhea, fever, stomach pains, and vomiting (8).

In reality, Salmonella, E. coli, Vibrio, or Bacillus—all of which are present in raw shrimp—cause over 90% of cases of food poisoning (15, 16, 17).

Additionally, eating raw shellfish like shrimp is a common source of the dangerous sickness norovirus (16, 18).

Globally, 1 billion cases of food poisoning involving diarrhea happen each year. Each year, foodborne infections alone cause about 5,000 fatalities in the United States (16).

As a result, older people, pregnant women, and young children should take extra precaution to stay away from raw or undercooked shrimp as these groups may have weakened immune systems and are therefore more likely to contract a fatal illness (17, 18).

Raw shrimp might be contaminated with pathogenic germs and viruses that cause disease or even death. Pregnant women and others with compromised immune systems, such as shrimp that is raw or undercooked, should take special steps to avoid consuming it.

What possible risks could eating raw shrimp present?

Since uncooked shrimp may carry dangerous bacteria, viruses, and even parasites, experts warn against eating them. Consuming them could result in disease and, in extreme circumstances, death.

Always take additional care to avoid eating raw or undercooked shrimp if you are a pregnant woman, a child, an elderly person, or someone else with a compromised immune system. Of course, people who are allergic to shellfish must also refrain from consuming any type of shrimp, whether it is raw or cooked.

A few possible risks of eating raw shrimp include cholera, vibriosis, and food poisoning. Eating raw, improperly prepared shrimp can result in many additional foodborne illnesses.

Shrimps can be eaten raw without any problems if they are cleaned, deveined, and stored at the right temperature where bacterial activity is least. The number of bacteria present in raw shrimp cooked with lemon, vinegar, or any other strongly acidic sauce is also rather low. As a result, these shrimp are suitable for eating.

In terms of texture, fresh shrimp will be chewable while undercooked shrimp will be meaty. Overcooked shrimp are famously tough. Shrimp that is cooked to perfection should fall between the two.

Checking the temperature of the shrimp is another way to confirm that it is done. Shrimp should be properly cooked when the heat source reaches 165 degrees Fahrenheit, but to be on the safe side, check their interior temperature, which should be 120 degrees Fahrenheit.

Others are allergic to both types of shellfish, while some people are allergic to just one. Most individuals with a shellfish allergy appear to also have a strong sensitivity to foods containing crustaceans.

The potential of cross-contamination or the emergence of new allergies may lead the doctor to advise patients with any sort of shellfish allergy to avoid any shellfish.

How long does poisoning from shrimp last?

After consuming the poisonous fish, symptoms of ciguatera poisoning typically start to manifest between a few minutes and six hours later. Numerous gastrointestinal, neurological, and cardiovascular problems are among them. The most typical signs of ciguatera toxicity are listed below. However, each person may have different symptoms.
