Ill health related to food-borne infection transcends all geographical, political and cultural boundaries. The incidence of food-borne diseases continues to adversely affect the health and productivity of populations in most countries, especially non-industrialised ones. However, since the 1950s, the emphasis in the industrialised world had shifted away from addressing public health problems, to problems of chemical contaminants etc., but recently food-borne infections have again become of increasing concern to governments and the food industry. Improvements in international transportation means food can be distributed throughout the world, but so can the parasitic pathogens which contaminate foods. Alternatively, tourists are being affected abroad and possibly transmitting the pathogen to others at home. Thus, an increasing number of food-related illnesses are international in scope. In this review parasitic contamination of foods of animal origin, particularly meat and fish, will be discussed together with potential problems associated with water and unwashed fruits and vegetables.
