Infections Or Ailments That You Could Get From Eating Raw Fish

Parasitic Infections

A parasite can be referred to as any being that gets its nutrients from another living organism, the host. This plant or animal parasite does not provide any benefits to the host. Some parasites do not cause any acute symptoms that are easily recognizable. Yet, many others could cause significant harm over an extended period. Parasitic infections are mainly common in people living in tropical countries. Parasitic infections are typically from drinking infected water or food not adequately cooked.

Here is a list and overview of a few of the primary diseases caused by parasites transmitted from eating raw fish.

Tapeworms 

People who eat undercooked or raw fish from freshwater or the sea have a high risk of getting fish tapeworms. You could also get tapeworms if you eat sea fish that spawn in rivers having freshwater. These fish also include salmon. 

Fish tapeworms are known to be the most significant parasite to infect humans, and they can reach up to a length of 15 meters, that is, 49 feet. They may not cause any symptoms, but you could contract a disease called diphyllobothriasis. The signs that you will experience are mild fatigue, diarrhea or constipation, stomach discomfort, etc. You may also experience a decrease in your vitamin B12 levels.

Liver Flukes

They are a family of flatworms that cause a disease named opisthorchiasis. People from Asia, South America, Eastern Europe, and Africa can most commonly get this parasitic disease. They feed off the host’s blood and cause gallbladder inflammation, bile duct infection, enlarged liver, and even liver cancer. The leading cause of this disease is consuming raw fish.

Roundworms

These cause a disease named anisakiasis. Though these parasites can live in humans for long, they cause severe immune reactions, which lead to vomiting, stomach pain, and inflammation. They are most common in South America, Japan, and the Netherlands.

Bacterial Infections

Bacterial infections may lead to food poisoning. That is another reason why we should always cook food to the optimum temperature before consuming it. You may experience the main symptoms if you have food poisoning: nausea, vomiting, diarrhea, and stomach discomfort. The bacteria found in raw fish which could be potentially harmful are Salmonella, Listeria, Clostridium, Vibrio. Surveys conducted in the United States reported that around 3% of domestic seafood and about 10% of raw seafood imported tested positive for Salmonella bacteria. The risk of food poisoning in healthy people may be less. Still, those with weak immune systems are very susceptible to bacterial infections.

Conclusion

Besides the various parasitic and bacterial infections transmitted from eating raw fish, there are other dangers. Raw fish could also have a high amount of pollutants. Persistent organic pollutants, that is, POPs, are very common in farmed fish such as salmon. Consuming more elevated amounts of such fish could lead to chronic diseases like type 2 diabetes and cancer. Though cooking cannot remove every type of contaminant in fish, it effectively removes the most harmful ones. Thus, it is always best to cook fish properly before eating.
