Tuna is a staple in many households, and Walmart is one of the largest retailers of canned tuna in the United States. With the rise of sushi and sashimi, many people are now consuming tuna raw. However, the question remains: can you safely eat Walmart tuna raw? In this article, we will delve into the world of tuna, exploring the risks and benefits of consuming it raw, and what you need to know before making it a part of your diet.
Understanding Tuna and Its Risks
Tuna is a type of fish that belongs to the Scombridae family. It is a carnivorous fish that is found in warm and temperate waters around the world. Tuna is a popular choice for sushi and sashimi due to its meaty texture and rich flavor. However, tuna can also pose some health risks if not handled and consumed properly.
Mercury Content in Tuna
One of the main concerns with consuming tuna is its high mercury content. Mercury is a toxic substance that can cause serious health problems, including neurological damage, kidney damage, and birth defects. Tuna, particularly bluefin and yellowfin, contain high levels of mercury, which can accumulate in the body over time.
| Tuna Type | Mercury Level (ppm) |
|---|---|
| Bluefin | 1.1-1.5 |
| Yellowfin | 0.3-0.6 |
| Albacore | 0.3-0.6 |
| Light Canned Tuna | 0.1-0.3 |
As you can see from the table above, bluefin and yellowfin tuna contain the highest levels of mercury, while light canned tuna contains the lowest levels.
Parasites and Bacterial Contamination
Another risk associated with consuming raw tuna is the presence of parasites and bacterial contamination. Tuna can contain parasites such as Anisakis, which can cause anisakiasis, a gastrointestinal infection. Additionally, tuna can be contaminated with bacteria such as Salmonella and E. coli, which can cause food poisoning.
Walmart Tuna: Is It Safe to Eat Raw?
Walmart is one of the largest retailers of canned tuna in the United States. However, the question remains: is Walmart tuna safe to eat raw? The answer is not a simple yes or no.
Walmart’s Tuna Sourcing
Walmart sources its tuna from various suppliers around the world. While Walmart has implemented sustainability and quality control measures, the company does not provide detailed information on its tuna sourcing.
Processing and Handling
Walmart tuna is processed and handled in accordance with FDA regulations. However, the processing and handling of tuna can affect its safety and quality. For example, if tuna is not stored at the correct temperature, it can become contaminated with bacteria.
How to Safely Eat Raw Tuna
If you still want to eat raw tuna, there are some precautions you can take to minimize the risks.
Choose Low-Mercury Tuna
Choose tuna that is low in mercury, such as skipjack or canned light tuna. Avoid bluefin and yellowfin tuna, which contain high levels of mercury.
Freeze the Tuna
Freezing tuna can kill parasites and bacteria. The FDA recommends freezing tuna at -4°F (-20°C) for at least 7 days to kill parasites.
Handle and Store Properly
Handle and store tuna properly to prevent contamination. Keep tuna refrigerated at a temperature below 40°F (4°C), and consume it within a day or two of opening.
Conclusion
While it is possible to eat Walmart tuna raw, it is essential to be aware of the risks involved. Mercury content, parasites, and bacterial contamination are all concerns that need to be addressed. By choosing low-mercury tuna, freezing it, and handling and storing it properly, you can minimize the risks and enjoy raw tuna safely. However, if you are pregnant, breastfeeding, or have a weakened immune system, it is best to avoid eating raw tuna altogether.
Remember, it is always better to err on the side of caution when it comes to food safety. If in doubt, cook your tuna to an internal temperature of at least 145°F (63°C) to ensure food safety.
By being informed and taking the necessary precautions, you can enjoy raw tuna while minimizing the risks. Happy eating!
