Around with fishing
Unfortunately, tuna fishing that ends up being served in the cans of canned goods that we buy in supermarkets is not regulated and affects the survival of other species, without going further dolphins, since they end up in their nets by mistake and end up dying without chance to survive after being caught, as they are not usually released after being caught in fishing gear.
Parasites
Another good reason to avoid the consumption of tuna is that inside these fish you can find hidden parasites that are dangerous to human health, microorganisms that are not always eliminated with cooking. In addition, it also highlights the presence of histamine in these fish, a substance that is formed in some fermented foods and fish (especially if it is poorly preserved), something that, in some cases can cause very allergy-like diseases. In the case of canned tuna, once opened, it is recommended to consume it quickly and not save any possible leftovers.
