Catfish is said to contain 3000 cancer cells. The news circulated on social media. Freshwater fish are also considered the dirtiest fish because they eat all kinds of dirt. The news made catfish cultivators, catfish pecel stall owners, and freshwater fish connoisseurs offended and devastated. The reason is, catfish is one of the favorite food menus in Indonesia. Almost every food stall, especially in East Java and West Java, always provides this menu. Besides the price is quite cheap, this menu is also delicious, so it becomes a special attraction for consumers. The news that catfish contains 3000 cancer cells first appeared in China. An article that mentions dirty and dirty catfish ads has gone viral on social media. The article mentions that human waste is also used as feed at a catfish farm in China. The article states that catfish is the dirtiest fish among other types of fish that are often consumed by humans. This is because catfish is a type of fish that easily breeds in dirty places. Catfish consume waste in the form of animal waste such as chickens, cows and pigs, and humans. This allows catfish to contain 3000 cancer cells which are very dangerous for the human body. However, catfish connoisseurs are asked not to be influenced by this information. The reason is, catfish advertising in Indonesia is different from China. Catfish in the country are cultivated very well by catfish breeders. They use pellets as their food, not using waste which is very harmful to human health like in China. Poor catfish cultivators, they were offended and very upset by the news. Information that catfish contains 3000 cancer cells is not true, said Head of the East Java Province Fisheries and Marine Service, Heru Tjahjono, Saturday (31/10)
