What chemical sometimes found in metal can liners has raised general health concerns regarding fertility or cancer links?
Answer
Bisphenol A (BPA)
One potential consideration when consuming canned products, including sardines, relates to the packaging materials used. Some metal can liners may contain Bisphenol A, commonly known as BPA. This synthetic chemical has become a subject of general health scrutiny due to reported potential links to certain long-term health issues, specifically concerning fertility and cancer risk. Although the levels reported in canned fish are often stated to be low, consumers concerned about this specific exposure can mitigate the risk by deliberately seeking out products explicitly labeled as BPA-free when making their purchasing decisions.
