Uncooked spoiled seafood can have sour, rancid, fishy, or ammonia odors. If you smell sour, rancid, or fishy odors in raw or cooked seafood, do not eat it. If you smell either a fleeting or persistent ammonia odor in cooked seafood, do not eat it.

Crabs host a ton of critters (bacteria) and they are completely harmless/killed during cooking. however if the crab dies before cooking, that bacteria breaks down the meat and generates the ammonia smell.

The best way to tell if your crab meat has gone bad is by its smell. Raw crab that is fresh will not smell at all, or will have a faintly sweet odor. Anything that smells sour, strong, fishy or rancid could mean the crab has spoiled and it should not be consumed.

In people, consumption of domoic acid causes nausea, diarrhea, and abdominal cramps shortly after eating tainted shellfish. Within 48 hours this can develop into headache, dizziness, confusion, motor weakness, and in severe cases, short-term memory loss, coma, and death.

CRAB CONTAINS LONG-CHAIN OMEGA-3 FATTY ACIDS Rich in vitamins and minerals, crab meat is also low in fat and contains Omega-3 polyunsaturated acids. Helps provide protection from heart disease and aids brain development. Some research suggests that Omega-3 also inhibits aggressive behavior.

Shellfish poisoning is caused by eating shellfish contaminated with bacteria or, more commonly, viruses. Contaminated shellfish include shrimp, crabs, clams, oysters, dried fish, and salted raw fish. Contaminated fish may have a tainted odor or taste.

Symptoms of Vibrio parahaemolyticus infection may include:

• Watery diarrhea.
• Abdominal cramps.
• Nausea.
• Vomiting.
• Fever.
• Headache.
• Bloody diarrhea.

Most people with a mild case of vibriosis recover after about 3 days with no lasting effects. However, people with a Vibrio vulnificus infection can get seriously ill and need intensive care or limb amputation. About 1 in 5 people with this type of infection die, sometimes within a day or two of becoming ill.

Vibriosis is an intestinal disease caused by small bacteria called vibrio. Vibrio are found in fish and shellfish living in saltwater and in rivers and streams where freshwater meets saltwater. Although there are several types of vibrio, Vibrio parahaemolyticus and related species are the most common in the northwest.

When ingested, Vibrio bacteria can cause watery diarrhea, often accompanied by abdominal cramping, nausea, vomiting, fever, and chills. Usually these symptoms occur within 24 hours of ingestion and last about 3 days. Severe illness is rare and typically occurs in people with a weakened immune system.

Treatment is not necessary in mild cases, but patients should drink plenty of liquids to replace fluids lost through diarrhea. Although there is no evidence that antibiotics decrease the severity or duration of illness, they are sometimes used in severe or prolonged illnesses.

You can reduce your risk of vibriosis by following these tips:

1. Don’t eat raw or undercooked oysters or other shellfish.
2. Always wash your hands with soap and water after handing raw shellfish.
3. Avoid contaminating cooked shellfish with raw shellfish and its juices.

Infection with Vibrio bacteria can cause two types of illness: vibriosis and cholera. Although many species of Vibrio exist, most vibriosis (non-cholera) cases are caused by Vibrio vulnificus or Vibrio parahaemolyticus.

In adults with noncholera Vibrio infections other than gastroenteritis, the combination of a third-generation cephalosporin (eg, ceftazidime, cefotaxime, ceftriaxone) and tetracycline or one of its analogues (eg, doxycycline) or a single-agent regimen with a fluoroquinolone (eg, levofloxacin, ciprofloxacin) is the …
