Foodborne pathogens enter the body through the intestinal tract where they cause temporary upsets. However, if they go from the intestinal tract into the bloodstream, they can invade other organs, systems, and structures, where they inflict damage such as some forms of heart disease, arthritis, and cancer. This book discusses the rising incidence of foodborne illness, and suggests ways in which the food regulators, and we, the consumers, can achieve a safer food supply.
