How catfish can have negative effects on humans

They have their harmful and dangerous part.That is, although they are delicious as food, they can cause allergies in some cases.This is due to its exposure to aquatic food contaminants.That is, in some cases, water mixes with food and heavy metals and mercury. Then when those fish eat those harmful aquatic foods, those harmful substances are absorbed by them.

Also, they are very high in fat and eating them can raise cholesterol levels which is also harmful in some cases.Therefore, care should be taken when feeding these fish to young children and the elderly.
