12. Raw Milk – Various Countries
Raw milk, or unpasteurized milk, is praised by some for its purported health benefits and superior taste. However, it can also harbor dangerous bacteria like E. coli, Salmonella, and Listeria. As a result, the sale of raw milk is banned or heavily restricted in many countries, including Canada, Scotland, and parts of the United States. Proponents argue for its nutritional benefits, while opponents cite significant health risks.
