问答题 Food safety is a scientific discipline concerned with handling, preparation, and storage of foods in ways that prevent foodborne illness. It involves a number of routines that should be followed to avoid potentially severe health hazards. Food can transmit disease from person to person as well as serve as a growth medium for bacteria that can cause food poisoning. Debates on genetic food safety include such issues as impact of genetically modified food on health of further generations and genetic pollution of environment, which can destroy natural biological diversity. In developed countries there are rigorous standards for food preparation, whereas in poverty-striken countries the main issue is the availability of adequate safe water.
