microbiological issues in food safety.'Food safety' refers to the content of various microbiological
and chemical elements in food.The FAO recognizes that all involved, from primary production to 
final preparation and consumption, share the responsibility for the supply of safe, healthy and 
nutritious food.In a global world trade context, a 'holistic food chain approach' recognizes that 
the responsibility for supplying safe and nutritious food lies with all involved in food production.Consumers have become more insistent that foods available in the marketplace should be of good 
quality, safe, and not pose risks to them.
