Q & A

Why is consuming too much canned tuna potentially harmful?

Eating too much canned tuna can be harmful due to its relatively high mercury content, which can have negative effects on health if consumed in large amounts.

What are some of the sustainability concerns associated with canned tuna?

Sustainability concerns with canned tuna include the potential for slavery, trafficking, and labor exploitation in the fishing industry, as well as questionable efforts to vet the labor supply chain.

How can consumers identify sustainably-sourced canned tuna?

What is the significance of the Marine Stewardship Council certification on canned tuna?

The Marine Stewardship Council certification indicates that the tuna is sustainably sourced, ensuring that it comes from a well-managed fishery that minimizes environmental impact.

How does mercury enter the food chain and why is it a concern in fish consumption?

Mercury enters the food chain through water, as it is a naturally-occurring element in the earth's crust. It is released into the atmosphere and dissolves into seawater, where fish ingest it. High mercury levels in fish can be harmful to humans when consumed.

What is scombrotoxin and how is it related to canned tuna?

Scombrotoxin is a type of food poisoning that occurs when tuna starts to spoil and produces a specific type of bacteria. It is caused by improper handling and can cause symptoms like a peppery taste, sweating, and dizziness.

What is Bisphenol A (BPA) and why might it be a concern in canned tuna?

Bisphenol A (BPA) is a chemical sometimes found in the lining of cans. While the FDA claims that the levels of BPA in cans are not harmful, there are potential health effects like infertility, cancer, and heart disease that have been associated with BPA, especially with copious amounts of canned food consumption.

How can consumers ensure they are buying uncontaminated canned tuna?

Consumers can ensure they are buying uncontaminated canned tuna by thoroughly checking cans for dents, holes, or cracks before purchase, and by discarding any cans with an off smell or color upon opening.

What are some alternative canned fish options that are low in mercury and sustainably sourced?

Alternatives to canned tuna include sardines, which are low in mercury and have a low environmental impact, and canned Alaskan salmon, which is sustainably sourced from North American waters.

What precautions should be taken when preparing a meal with canned tuna to avoid health risks?

When preparing a meal with canned tuna, one should ensure the can is not damaged, check for proper storage conditions to prevent spoilage, and be aware of the potential health risks associated with high mercury content and the presence of BPA.
