Catfish is a fish that is quite popular in Indonesia. But lately there has been a lot of news that eating catfish is harmful to the body. Then is it true? Many news circulating on social networks say that catfish is the filthiest fish. There is an article entitled In a mouthful of catfish meat, there are 3000 cancer cells. The title of the article made a hot topic of conversation on social media. The news made catfish farmers nervous, because it could threaten the continuity of their business. The article posted on July 29, 2015 describes the confession of a catfish farmer from China named Zhang Ri-hong, who supplies catfish to street markets and restaurants in Hainan Province. The media then investigated the catfish and tried to observe seven samples of catfish producer ponds. The seven ponds are surrounded by chicken and pig coops, while in the middle of the ponds there are many piles of garbage. As reported by kompas.com (28/10/2015), the article was a black campaign to bring down sales of the catfish market whose market prospects continued to increase, said the Head of the East Java Fisheries and Marine Service. Basically catfish that are dangerous to eat are catfish that live in dirty environments. Catfish that live in a dirty environment have the potential to be exposed to very dangerous chemical compounds such as metals and substances that can be polluted through water pollutants. The most dangerous chemical compound that catfish can possibly eat is mercury. Mercury itself is an organic chemical compound that is very toxic and can damage the human nervous system when consumed. But you don't have to worry about the widespread rumor that catfish contains cancer cells. In Indonesia, generally the catfish that are marketed are not those from the wild, but catfish that are cultivated in ponds that have been treated and protected from pollution. The food for catfish also comes from non-waste feed, so it is not exposed to harmful chemical compounds. According to detik.com (23/10/2015), currently there is no research that states that consuming catfish can trigger cancer, said Dr. Dradjat R Suardi, SpB(K)Onk, a cancer expert from the Indonesian Oncology Association. Quoted from alodokter.com, every 100 grams of catfish contains 229 kilocalories of energy.
