Aflatoxins are poisonous substances made by certain molds that contaminate about a quarter of the world’s food supply and are known carcinogens. This review examines the latest methods for detecting these toxins (from simple lab tests to advanced smartphone-powered devices) and ways to remove or prevent them, including using beneficial bacteria and special plasma treatment. The research shows that combining multiple approaches—detection technology with biological solutions—works best for keeping our food and animal feed safe from these dangerous contaminants.
