Catfish, with its delicate taste and culinary appeal, often finds its way onto our plates. Yet, the prospect of accidentally consuming undercooked catfish can raise understandable concerns about health and safety.

Whether you’ve encountered the unexpected experience of undercooked catfish or wish to be better informed about its potential risks, understanding the ins and outs of this scenario is crucial.

Let’s explore the nuances of undercooked catfish consumption to ensure your dining experience remains both enjoyable and safe.

How Can You Tell If Catfish Is Undercooked?

Determining if catfish is properly cooked involves a few indicators:


Cooked catfish turns opaque and white. If it’s undercooked, it might appear somewhat translucent and a bit gelatinous.


Properly cooked catfish should be firm yet flaky. Undercooked catfish might feel too soft or mushy.

Internal temperature:

The safest way to ensure catfish is fully cooked is by checking its internal temperature. It should reach at least 145°F (63°C) to ensure it’s safe to eat. Use a food thermometer inserted into the thickest part of the fish to check the temperature.


If you’re baking, frying, or grilling catfish, follow recommended cooking times. Undercooked fish might not have been cooked for the required duration.

If you’re unsure, it’s better to err on the side of caution and cook the catfish a little longer. Eating undercooked fish can pose health risks, so ensuring it’s properly cooked is essential.

What is the texture of undercooked catfish?

Undercooked catfish often has a texture that’s different from properly cooked fish. It might feel overly soft, mushy, or even slightly slimy.

When fish is undercooked, the proteins haven’t had a chance to denature fully, resulting in a texture that lacks the firmness and flakiness you’d expect in properly cooked fish.

It might also appear somewhat translucent and not have the opaque, white appearance of cooked catfish.

Is it okay if catfish is a little pink?

In general, catfish, like most fish, should not have any pink areas when fully cooked. Pinkness in fish can indicate undercooking, and it’s not advisable to consume undercooked fish due to the risk of bacterial or parasitic contamination.

The recommended safe internal temperature for fish, including catfish, is 145°F (63°C). At this temperature, the fish should be opaque and flake easily with a fork.

If there are pink areas, especially in the thickest parts of the fish, it’s better to cook it a bit longer to ensure it’s fully cooked through.

What color is undercooked catfish?

Undercooked catfish might have a translucent appearance rather than the opaque, white color of properly cooked fish.

It can appear somewhat gelatinous or translucent with a hint of rawness. This is because the proteins in the fish haven’t fully denatured, resulting in a texture and color that differ from fully cooked catfish.

Undercooked fish may have areas that look more translucent and less opaque compared to properly cooked portions.

How to fix undercooked catfish – a comprehensive guide

Fixing undercooked catfish depends on how undercooked it is and the method of cooking used. Here’s a comprehensive guide:

Identify undercooked areas:

Check the catfish thoroughly to determine which parts are undercooked. This will help you focus on those areas while recooking.

Finish cooking in the oven:

If the catfish was baked or grilled, place it in a preheated oven at around 350°F (175°C). Cover it with foil to prevent excessive drying.

Cook it for a few minutes, checking regularly until it reaches an internal temperature of 145°F (63°C). This allows for more controlled cooking without burning the outside.


For pan-fried catfish, heat a skillet with a bit of oil or butter over medium heat. Cook the undercooked side first, flipping it occasionally until it reaches the desired doneness. Cover the pan with a lid or foil to help the heat circulate and cook the fish evenly.

Use the microwave cautiously:

It’s possible to use the microwave to finish cooking, but it can result in uneven cooking and texture changes. Microwave the undercooked catfish in short intervals, checking after each to avoid overcooking. Cover it to trap steam and aid in cooking.

Steam it:

Place the undercooked catfish in a steamer basket or wrap it loosely in foil to create a makeshift pouch. Steam it over boiling water until it reaches an internal temperature of 145°F (63°C). This method helps retain moisture.

Utilize moist heat:

If the undercooked catfish is in a sauce or broth, simmer it gently until the fish reaches the safe internal temperature. The moisture and heat from the sauce can help finish cooking without drying out the fish.

Remember to check the temperature with a food thermometer to ensure it reaches the recommended safe temperature throughout.

Be cautious not to overcook it while fixing the undercooked portions, as this might compromise its texture and flavor.
