Food, along with air and water, is one of the most important factors for the existence of living beings. Food toxicity is the study of chemicals in foods that, when ingested, can be harmful to humans. Food toxicology focuses on determining the severe effects of chemicals in foods on living systems. They can also be generated during meal preparation, processing, and storage. Food Science and Environmental Toxicology students need to know the basic chemical and biological characteristics of hazardous chemicals, present in food. Food poisoning is currently attracting a lot of attention from the food industry, colleges, and government organizations, and it is also causing a lot of anxiety among consumers. The belief that foods are safe to eat is based on their consumption history. Consumers have become increasingly interested in the "health-promoting" properties of many natural food ingredients in recent years.
