 In the Rupununi region in particular, the local peanut crop needs to be tested for aflatoxins, a group of carcinogenic toxins that occur in the soil.Guyanese farmers are obliged to comply with the Guyanese Food and Drug Department (FDD) and cannot sell peanuts unless they are certified as free of all aflatoxins.Current food safety testing and certification mechanisms cannot keep up with the increased demand for testing, leaving peanut harvests ineligible for export.
