Anisakis - 10 things to know with detail

• Anisakis is a genus of parasitic nematodes, or roundworms, that infect fish and marine mammals. They are commonly found in the stomach and intestines of these animals.
• Humans can become infected with Anisakis by consuming raw or undercooked fish or squid that contain the larvae of the parasite. This can lead to a condition known as anisakiasis.
• Symptoms of anisakiasis can include abdominal pain, nausea, vomiting, and diarrhea. In severe cases, the larvae can penetrate the intestinal wall and cause inflammation and tissue damage.
• Anisakiasis is most commonly reported in countries where raw fish is consumed regularly, such as Japan, Spain, and Italy. Cases have also been reported in the United States and other countries.
• The best way to prevent anisakiasis is to thoroughly cook fish and seafood before consuming it. Freezing fish at a temperature of -20°C (-4°F) for at least 7 days can also kill the larvae.
• Anisakis larvae can survive for several weeks in the human digestive tract, but they cannot mature into adult worms in humans. Instead, they are eventually passed out of the body in feces.
• In rare cases, Anisakis larvae can migrate to other parts of the body, such as the stomach lining, the liver, or the lungs. This can lead to more serious complications and may require surgery to remove the larvae.
• Diagnosis of anisakiasis is usually based on symptoms and a history of consuming raw or undercooked fish. In some cases, a tissue biopsy or imaging tests may be necessary to confirm the presence of the larvae.
• Treatment for anisakiasis typically involves removing the larvae from the digestive tract through endoscopy or surgery. In some cases, medications may be prescribed to help alleviate symptoms.
• It is important to be cautious when consuming raw or undercooked fish, especially in areas where Anisakis infection is common. Proper food handling and preparation practices can help reduce the risk of anisakiasis and other foodborne illnesses.
