Yes. Tilapia can contain trace amounts of methylmercury, as nearly all fish do. The U.S. FDA and EPA classify tilapia as a Best Choice—one of their lower-mercury options—but that does not mean it is mercury-free or that every fish has the same level.

How much mercury is in tilapia?

The FDA and EPA’s Best Choice category indicates that tilapia is among the lower-mercury fish in their consumer advice. It is a category, not a measurement or guarantee for an individual fillet, brand, or batch. The FDA explains that nearly all fish and shellfish contain trace methylmercury, while most types do not have levels expected to cause health effects for adults. FDA: Mercury in Food

For context, an EPA technical table reports a mean of 0.01 parts per million (ppm) for tilapia. This is a historical average based on FDA commercial-fish monitoring data from 1990–2012, not a current test of a particular product or serving. EPA: Fish Advice Technical Information

Who should pay closest attention to fish advice?

Methylmercury can affect the developing nervous system, so FDA/EPA fish advice is especially relevant to people who might become pregnant, are pregnant or breastfeeding, and children. It recommends eating fish while choosing lower-mercury options and following the serving guidance. FDA: Advice about Eating Fish

How much tilapia can you eat?

During pregnancy and breastfeeding

FDA/EPA recommends 2 to 3 servings a week from the Best Choices list. One adult serving is 4 ounces, measured before cooking. These are U.S. recommendations for this group; they are not a universal limit for every adult. FDA: Advice about Eating Fish

For children

Children should have portions suited to their age. EPA lists these typical serving sizes:

These are serving sizes, not a recommendation to eat tilapia at every meal. Follow the FDA/EPA weekly advice for the relevant age group and vary the fish served. EPA: EPA-FDA Advice about Eating Fish and Shellfish

Does advice differ for locally caught tilapia?

Yes. The Best Choice classification applies to the commercial fish covered by the FDA/EPA consumer list; it does not tell you whether fish caught from a particular lake, river, or other waterbody is safe. Check local fish advisories for the water where the fish was caught. If no advisory is available, FDA/EPA advises eating only one serving of that fish and no other fish that week.

What the Best Choice label does—and does not—mean

It means tilapia is in the agencies’ lower-mercury category for fish advice. It does not mean zero mercury, unlimited portions, or a guaranteed mercury level for a specific fillet. For commercial tilapia, follow the serving guidance that applies to you; for local catch, use the advisory for the specific waterbody.
