The human burden of infection caused by food-borne protozoan parasites is enormous; billions of people are infected world-wide and the DALY (disability-adjusted life year) toll due to these infections is correspondingly huge. Whilst some infections may result in mild, relatively insignificant clinical disease, others may be seriously debilitating or even fatal. This book provides detailed insights into those protozoa who are currently most relevant regarding food-borne transmission. This book is intended to be of use and interest for a range of professionals, from researchers to regulators, from diagnosticians to parasitologists to food technologists; it should be read by those who work in academia, within the various branches of the food industry and food research associations, in government regulatory agencies, and in environmental health departments.
