Primer on food-borne pathogens for subsistence food handlers.

Subsistence food preparations may lead to human illnesses caused by pathogenic bacteria and viruses. Little is known about the incidence of food-borne illnesses other than botulism in circumpolar indigenous populations. Lack of documentation for other pathogens may be related to the sparsely populated communities involved, limited laboratory analysis, and non-lethality to healthy individuals. This overview covers the major food-borne pathogens, their sources, transmission, growth parameters, and prevention. Examples of indigenous peoples' food preparations that may be susceptible to pathogenic bacterial growth and toxin formation are described.
