Tuna and Mercury Poisoning: A Growing Concern

Mercury is a naturally occurring element in the environment that can also be released into the air through industrial pollution. As a result, it's essential to understand the risks associated with consuming fish and shellfish, particularly for women who are pregnant or may become pregnant, breastfeeding mothers, and young children.

One of the most commonly consumed fish that contains higher levels of mercury is albacore tuna, also known as 'white' tuna. In fact, studies have shown that albacore tuna contains more mercury than canned light tuna. On the other hand, some fish like shrimp, canned light tuna, salmon, pollock, and catfish are low in mercury and considered safe to consume.

The Food and Drug Administration (FDA) and Environmental Protection Agency (EPA) recommend that women who may become pregnant, pregnant women, breastfeeding mothers, and young children avoid certain types of fish that contain high levels of mercury. These include Shark, Swordfish, King Mackerel, and Tilefish.

In addition to the FDA/EPA advice, there are three key recommendations for selecting and eating fish or shellfish:

1. Eat up to 6 ounces (one average meal) per week of fish you catch from local waters.

2. Choose fish and shellfish that are lower in mercury, such as shrimp, canned light tuna, salmon, pollock, and catfish.

3. Avoid eating Shark, Swordfish, King Mackerel, or Tilefish due to their high levels of mercury.

While the risk from mercury in fish and shellfish is generally low for most people, it's essential to be aware of the potential risks, particularly for women and young children. Consuming large amounts of fish and shellfish containing higher levels of mercury can harm an unborn baby or young child's developing nervous system.

On the other hand, a well-balanced diet that includes a variety of fish and shellfish can contribute to heart health and children's proper growth and development. Fish and shellfish are an excellent source of high-quality protein, omega-3 fatty acids, and essential nutrients like vitamin D and selenium.

In conclusion, while tuna and mercury poisoning may seem like a growing concern, there are steps you can take to minimize your exposure to this harmful element. By choosing fish and shellfish that are lower in mercury and following the FDA/EPA advice, women who are pregnant or may become pregnant, breastfeeding mothers, and young children can enjoy the many nutritional benefits of fish and shellfish while keeping their health and well-being in mind.
