Speaking of fish, it can be said to be an indispensable delicacy on the daily table, and the most common fish on the table are cod , dragon li fish , and crucian carp . Of course, in addition to these most common fish, there are also many uncommon fish, such as the "notorious" canned herring and the oil fish that have been blacklisted by many countries. So are oil fish poisonous? Why are you so unpopular?
It is reported that oil fish is the nickname of thorn-scaled snake mackerel and heteroscaled snake mackerel , and it mainly reproduces in the lower and middle water layers of southern my country. This kind of fish has lived in the deep sea for a long time, and the fish bladder deteriorates. In order to increase buoyancy to yourself, the whole body is covered with thick oil, so more than 40% of the body of the oil fish are wax ester . Of course, oil fish itself is not poisonous, but ordinary people often "spray oil on their butts" after eating oil fish, and even symptoms such as diarrhea, stomach cramps and . The reason for this situation is that the human body's stomach and intestines cannot adapt to the natural wax in the oily fish. This wax is the main murderer of stomach cramps, so oil-exciting diarrhea will also occur. In addition, wax is indigested, so yellow oil is discharged, which will indirectly stain your clothes and pants.
So is it because of the different cooking methods of oil fish that different situations occur? In order to verify this, many people have used steaming, braised, salt roasting, sashimi and other methods to make oil fish, but in the end they all received a "toilet one-day tour". Some people even had oil leaks for three days after eating oil fish and were forced to change into three pairs of pants. Therefore, oil fish is blacklisted by European and American countries and is strictly prohibited from entering the local area. However, because the meat quality of cod and oil fish is very similar, many vendors often "sell dog meat with the head of sheep". So how to distinguish oil fish from cod?
First, from the appearance, the cross-section of cod is relatively large, generally mainly cylindrical, and the fish meat is mainly white, without obvious red lines. The cross-section of the oil fish is relatively small, with a light yellow or light red line in the middle, and the fish meat is divided into several areas. Compared with the fish meat of cod, it will show a yellowish and gray color.
Second, the scales of cod are smaller, the scale patterns are thinner, there are many small dots on the body, and the scales of the oil fish are larger. More importantly, cod will not actively scrape the scales when sold, and the one that scrapes the scales is likely to be oil fish.

Third, the cod feels very silky after thawing, while the oily fish feels rougher. Moreover, the price of cod is basically 100 yuan per catty, while the price of oil fish ranges from 10 yuan to several dozen yuan.
Finally, the meat of cod tastes more delicate and tastes more delicious, while the meat of oil fish is rougher, and the taste is like chicken, which is not good.
So when buying cod, don’t be deceived. You must tell whether it is cod or oil fish. If you can't tell the difference clearly, you're likely to receive a "toilet day trip" and change to a few pairs of pants.
