Sodium nitrite, often used as a preservative in processed meats like bacon, sausages, and ham, has been a topic of concern regarding its potential link to cancer. The International Agency for Research on Cancer (IARC), part of the World Health Organization, classifies sodium nitrite as a Group 2A carcinogen, which means it is probably carcinogenic to humans, based on evidence that its consumption can lead to the formation of N-nitroso compounds, some of which are known carcinogens. It's advisable to limit consumption of processed meats containing sodium nitrite to reduce potential health risks.
