When it comes to enjoying fish, most of us focus on the quality of the fish meat and tend to overlook other parts, which may contain more impurities than you think. Among the various parts of a fish’s body, some can harbor more bacteria and contaminants than even its intestines, and experts advise that they be completely removed before cooking and consumption. Here’s a detailed look at these parts and why you should pay attention.

1. Spines and Reproductive Organs

The spines and reproductive organs of fish are often overlooked during preparation. However, these areas can accumulate bacteria and contaminants due to their biological nature.

Spines: This part contains connective tissue and can harbor bacteria if not thoroughly cleaned. In some cases, spines may contain harmful toxins or contaminants from the fish’s environment.
Reproductive Organs: Similar to spines, the reproductive organs can harbor bacteria and contaminants from the fish’s digestive and physiological processes. This is especially concerning when the fish is not prepared immediately and is not stored properly.

2. Gills and Mouth

The gills and mouth of the fish are often overlooked during processing. They are a common site for the accumulation of bacteria, parasites, and contaminants.

Gills: Fish gills are respiratory organs that filter oxygen from the water. As a result, they can contain dirt, including bacteria and contaminants from the water in which the fish lives.
Mouth: The fish’s mouth may contain food debris, bacteria, and parasites. Failure to clean this area can lead to the risk of infection.

3. Head and Operculum

The head and operculum are often overlooked during fish preparation. Experts advise that these parts also need to be thoroughly cleaned or removed entirely to ensure safety.

Head: In addition to soft tissue, the head of the fish contains oily glands and contaminants that can be harmful if not cleaned properly.
Operculum: The operculum can accumulate bacteria and dirt from the fish’s environment.

4. Slime and Fish Fat

Slime and fish fat are also considerations when preparing fish. They can contain contaminants and saturated fats that are not beneficial to health if consumed in excess.

Slime: Slime can facilitate the growth of bacteria and mold. Removing the slime layer reduces the risk of infection and improves the quality of the dish.
Fish Fat: While fish fat contains beneficial omega-3 fatty acids, it can also harbor toxins and contaminants if not handled properly.

Expert Advice

Thorough Cleaning: Ensure you clean the fish thoroughly before preparation, especially the parts prone to bacterial accumulation, such as gills, mouth, and operculum.
Remove Unnecessary Parts: Get rid of spines, reproductive organs, and other unnecessary parts to reduce the risk of infection and improve the flavor of the dish.
Prepare Immediately: Try to prepare the fish as soon as possible after purchase or catch to minimize bacterial growth.
Proper Storage: If not preparing immediately, store the fish in cold, clean conditions to reduce the risk of bacterial contamination.

Understanding and applying proper fish cleaning and preparation techniques not only enhances the taste of your dish but also safeguards your health and that of your family. Always pay attention to every part of the fish to ensure you’re consuming safe and high-quality food.

Frequently asked questions

The liver and the intestines are considered the dirtiest parts of a fish as they filter and store toxins, heavy metals, and pollutants that the fish is exposed to in its environment.

The liver and intestines can contain high levels of toxins and pollutants, which can be harmful to human health if consumed in significant quantities. These toxins can accumulate in the body over time, potentially leading to health issues.

While it is generally advised to avoid consuming the liver and intestines due to toxin levels, some cultures consider these parts a delicacy. In small quantities, and if properly prepared and cooked, these organs can provide nutrients such as vitamins A and D, as well as omega-3 fatty acids.

To minimize the risk, it is recommended to choose wild-caught fish from less polluted waters, as they tend to have lower toxin levels. Additionally, opt for smaller fish as they are less likely to have accumulated high levels of toxins. Properly cleaning and preparing the fish, including removing the intestines and liver, can also help reduce potential toxin exposure.

You can find vitamin A in orange and green vegetables, such as carrots, sweet potatoes, spinach, and kale. Vitamin D can be obtained through exposure to sunlight, and it is also found in egg yolks, fatty fish like salmon, and fortified foods such as dairy products and cereals.
