The jack crevalle is a species of fish found in the Gulf of Mexico and the Caribbean Sea. It’s a popular gamefish known for its fighting abilities and delicious taste.

But is it safe to eat? We’ll discuss some of the potential health risks associated with eating this type of fish, as well as provide helpful tips on how you can reduce your risk of getting sick.

The Potential Risks Associated with Eating Jack Crevalle

The first thing to keep in mind when consuming any type of fish is that it contains mercury. This is especially true for large predatory fish such as the jack crevalle, which has higher levels than smaller species.

Eating too much mercury can cause serious health problems such as damage to the nervous system or reproductive organs.

Another potential risk associated with consuming this type of fish is ciguatera poisoning. Ciguatera poisoning occurs when people consume certain types of reef fish that have eaten toxic algae containing ciguatoxin.

Symptoms can include vomiting, nausea, and diarrhea, along with other more severe symptoms such as tingling sensations in the hands and feet or even temporary paralysis.

Unfortunately, there’s no way to detect whether or not a fish contains ciguatoxin before consumption, so it’s important to be aware of this potential risk when eating jack crevalle or any other type of reef fish.

Tips for Reducing Your Risk

Fortunately, there are a few easy steps you can take to reduce your risk when consuming jack crevalle or any other type of fish:

  1. Pay attention to local advisories about specific species in your area and make sure you read up on their size and seasonality before fishing for them.                                                
  2. Only purchase fresh-caught wild caught or sustainably farmed seafood from reputable sources whenever possible.
  3. Eat only small amounts (no more than six ounces per week) at a time to limit your exposure to toxins like mercury and ciguatoxins found in some types of seafood.       
  4. Avoid eating raw seafood completely due to the potential risks associated with bacteria and parasites that can be present in uncooked products like sushi or sashimi.                               
  5. Be aware that some species may contain high levels of contaminants like PCBs so choose carefully when selecting what types of seafood you eat regularly.                     
  6. If you are pregnant or nursing, always talk to your doctor before consuming any type of seafood since there may be additional risks associated with certain types.


Ultimately, if prepared properly and consumed responsibly, jack crevalle can be an enjoyable part of a healthy diet.

However, it’s important to be aware that there are potential risks involved due diligence should always be taken by researching local advisories, purchasing sustainably harvested seafood from reputable sources, limiting portion sizes, avoiding raw preparations, and consulting with your doctor if necessary.

By following these simple guidelines, you can enjoy all the benefits this delicious gamefish has to offer while reducing your risk for any potential health concerns.
