Cooking can destroy some types of mold toxins, but it depends on the specific toxin and the temperature and duration of cooking. Some mold toxins are heat-stable and can withstand high temperatures, while others may be more susceptible to degradation. It is important to note that even if mold toxins are destroyed, the presence of mold itself on the dishes indicates potential contamination and should be addressed by proper cleaning and, if necessary, discarding the affected items.
