How can a dirty knife cause food poisoning?

Answer 1

A dirty knife can harbor harmful bacteria, viruses, or other pathogens from prior use, especially if it has come into contact with raw meat, fish, or unwashed produce. When the knife is used to cut other foods, these contaminants can transfer, leading to cross-contamination. Consuming food contaminated in this way can result in food poisoning, as the pathogens can multiply and cause illness when ingested. Proper cleaning and sanitizing of kitchen utensils are essential to prevent this risk.
