Menu "Raw salmon" or Japanese-style sashimi remains one of the top favorite dishes among Thais but often raises questions and concerns online, especially about whether eating raw salmon increases the risk of liver fluke infection like eating raw freshwater fish does ? To help consumers understand correctly and eat with peace of mind, let's explore the facts in depth.

Clearing the doubt: Does "salmon" really have liver flukes?

"Liver fluke" (Opisthorchis) has a very specific life cycle and grows in freshwater fish, especially carp family fish (such as white fish, minnows, and mrigal), which are ingredients in traditional raw or fermented dishes like koi pla, pla som, or raw fermented fish — the main causes of bile duct cancer in Thailand.Quick check: 10 risky foods for "liver fluke disease" — beware of parasite larvae hiding in many commonly eaten Thai dishes

Meanwhile, salmon (Salmon) is an anadromous fish born in freshwater but grows in saltwater. Its environment is unfavorable for liver fluke development, so salmon meat does not carry the risk of liver fluke infection.

Currently, the global popularity of raw food, especially Japanese cuisine, has expanded widely, leading to increased detection of p arasites in raw fish compared to decades ago. Although salmon is safe from liver flukes, eating raw salmon still carries risks from other sea-dwelling parasites. It is recommended to consume from clean, trustworthy sources or restaurants.

Know the 3 main parasite groups in raw food and recognize symptoms if accidentally infected

Parasitologically, common parasites found in raw fish and raw dishes are classified into three major groups:

1. Roundworms

are common in sea fish and squid such as cod, salmon, herring, cutlassfish, and pomfret. They usually invade the stomach or intestinal lining causing nausea, vomiting, diarrhea, and sudden severe abdominal pain.

2. Flatworms or tapeworms

are found in both freshwater fish and some other fish species. When inside the body, they grow long in the intestines, often causing bloating, abdominal distension, cramping pain, unexplained weight loss, and possibly anemia due to nutrient absorption by the parasite.

3. Liver flukes

are found in freshwater fish and fermented foods like pla ra or koi pla. Some species are highly dangerous and can penetrate the digestive system to the liver or lungs, causing fullness, bloating, diarrhea, and if they invade vital organs such as the liver or gallbladder, can lead to severe long-term damage.

Prevention guidelines for liver fluke infection for "sashimi lovers"

In summary, "Salmon does not have liver flukes" but there remains risk from other marine parasites like tapeworms. Therefore, consumers should follow these safety measures:

• Consume only sashimi-grade fish Buy or eat from reputable outlets with certified freezing and safe handling systems
• Avoid eating raw freshwater fish because freshwater fish have higher and more dangerous parasite prevalence than saltwater fish
• Check the physical texture before eating Fish meat must be fresh and firm, without dark coloration, thick mucus, or abnormal strong fishy odor

However, if abnormal symptoms appear after eating raw fish, see a doctor for stool, blood, or endoscopic tests for accurate diagnosis and safe treatment.
