What makes some fish inedible?
While fish is considered a healthy and delicious source of protein, not all fish are created equal. There are certain species of fish that are considered inedible due to various reasons such as toxicity, high levels of contaminants, or simply not being fit for human consumption.
If you’re a seafood lover, it’s important to be aware of what makes certain fish inedible to avoid any potential health risks. In this article, we’ll delve into the reasons why some fish are considered inedible and which fish you should avoid consuming.
Toxicity
- Ciguatera: This is a type of food poisoning that can be caused by consuming fish that have accumulated toxins produced by certain types of microscopic algae. The toxins can cause symptoms such as vomiting, diarrhea, and neurological problems. Species that are known to carry the toxin include barracuda, grouper, and snapper.
- Tetrodotoxin: This is a potent toxin found in some species of pufferfish, which can cause paralysis and even death. In Japan, pufferfish (also known as fugu) is considered a delicacy, but it must be prepared by specially trained and licensed chefs to ensure that the toxic parts of the fish are removed.
Contaminants
- Mercury: Some fish, particularly larger predatory species, can contain high levels of mercury, which can be harmful to human health. Pregnant women and children are particularly susceptible to the harmful effects of mercury. Species such as shark, swordfish, and king mackerel are known to have high levels of mercury and should be avoided or consumed in moderation.
- PCBs: Polychlorinated biphenyls (PCBs) are industrial pollutants that can accumulate in the flesh of certain fish. PCBs have been linked to various health problems including cancer and neurological damage. Species that are known to contain high levels of PCBs include farmed salmon, bluefish, and striped bass.
Fitness for human consumption
Some fish are simply not fit for human consumption due to their texture, taste, or potential health risks. For example, the oil from liver of the dogfish shark contains high levels of vitamin A, which can be toxic in large amounts. Other fish such as jellyfish or blowfish may simply be unappetizing or require specialized preparation methods.
While it’s important to be aware of which fish are inedible, it’s also important to remember that many fish are safe and healthy to consume in moderation.
