Detection Methods for Contaminated Food

Neha Shrivastava, Shaily Thakur

Abstract: Food contamination is the term used to describe the presence of undesired and hazardous chemicals on food items that can result in foodborne disease. Food deterioration and the ensuing foodborne illness can be caused by physical, chemical, biological, or environmental pollutants. The public's health is now seriously threatened by food contamination. Statistical measurements in the last few decades have produced many negative results. Food contamination causes 420, 000 deaths and 600 million illnesses globally each year. Food safety ensures that consumers are protected from foodborne illnesses. The food may be impacted by a number of significant factors, including microbiological, chemical, nutritional, and natural variations, water flow, climate changes, and natural cleanliness. Food spoils as a result of contaminants that enter throughout the processes of preparation, storage, preservation, and transportation. The pollutants can be found using a variety of techniques, such as molecular biology - based, immunological, and culture - based techniques. These techniques are quick, extremely sensitive, precise, and economical. For the long - term detection or identification of foodborne pathogens, this review offers a thorough overview of food contaminants and their detection methodologies, including both traditional and cutting - edge approaches.
