Step-by-step explanation:
Symptoms associated with hypersensitivity to the ingestion of a food can derive from diverse sources including chemical contaminants, microbial contaminants, and parasitic contaminants. These contaminants can lead to foodborne diseases, which often manifest with gastrointestinal symptoms such as abdominal discomfort, nausea, diarrhea, and vomiting. Chemical contaminants can include things like agrochemicals and environmental contaminants, which can be present in food due to various factors and may be unaffected by cooking processes.
