Define Visible Hazards in food
Physical hazards, as you would realize, include non-living things in foods, such as stones, inedible stones, hair, glass, metal, wood, plastic, insulation material etc. These materials can become a part of foods from the environment.
Now, how do these get into foods that we eat? Well, there can be many ways. It could be from the environment in which the foods are grown or contamination could occur during processing and packaging e.g. iron fillings from worn out machinery, processing tea. Yes, the use of electronic metal detector in many food processing operations can help
in detecting and screening harmful metallic pieces. Inspite of availability of various mechanisms and technologies to prevent the risks caused due to physical contaminants, foreign / extraneous objects still represent one of the largest categories of complaints by consumers. Hence, it is the job of the government and industry to ensure that these risks are minimal and acceptable.
