Vomiting or diarrhea, depending on whether diarrheic or emetic toxin present abdominal cramps nausea Staphylococcus aureus and its enterotoxins Nausea, vomiting, retching, diarrhea, abdominal pain, prostration The symptoms, onset of symptoms and the most common responsible microorganisms for the major foodborne illnesses are shown on Table 1. The most severe cases tend to occur in the very old, in the very young, in those who have compromised immune system function, and in healthy people exposed to a very high dose of an organism. More than 200 different food-borne diseases have been identified. In foodborne infections, since an incubation period is usually involved, the time from ingestion until symptoms occur is much longer than that of foodborne intoxications.
Thus, foodborne illness is generally classified into: (a) foodborne infection and (b) foodborne intoxication. įoodborne illness occurs when a pathogen is ingested with food and establishes itself (and usually multiplies) in the human host, or when a toxigenic pathogens establishes itself in a food product and produces a toxin, which is then ingested by the human host. A foodborne disease outbreak is defined as the occurrence of two or more cases of similar illness resulting from the ingestion of a common food. viruses, bacteria, parasites) are biological agents that can cause a foodborne illness event. The association between the consumption of food and human diseases was recognized very early and it was Hippocrates (460 B.C.) who reported that there is a strong connection between food consumed and human illness. In addition, the application of suitable food safety education programs for all involved people in the production and consumption of foods is suggested. In this context, a food safety management system should be designed in a way to estimate the risks to human health from food consumption and to identify, select and implement mitigation strategies in order to control and reduce these risks. Food safety management systems based on to classical hazard-based approach has been proved to be inefficient, and risk-based food safety approach is now suggested from leading researchers and organizations. and Yersinia enterocolitica), viruses (Hepatitis A and Noroviruses) and parasites ( Cyclospora cayetanensis, Toxoplasma gondii and Trichinella spiralis), together with some important outbreaks, are reviewed. The characteristics of the most common pathogenic bacteria ( Bacillus cereus, Campylobacter jejuni, Clostridium botulinum, Clostridium perfringens, Cronobacter sakazakii, Esherichia coli, Listeria monocytogenes, Salmonella spp., Shigella spp., Staphylococccus aureus, Vibrio spp. Foodborne pathogens are causing a great number of diseases with significant effects on human health and economy.
