Chapter 4 Zoonoses: implications for food safety
-
, , , and
Abstract
Foodborne zoonotic microorganisms are major pathogens that cause human diseases with significant implications for health and food safety. Infections due to these pathogens are acquired when foods contaminated with vegetative cells or their toxins are consumed, resulting in significant economic and public health consequences globally. Hence, this chapter highlights the background and significance of foodborne zoonotic agents belonging to the major classes of microbial species, including bacteria, fungi, viruses, protozoans, and infectious particles (prions). Generally, food animals tend to be the major reservoir of these pathogens, and foods or food products originating from animals are the major vehicle of transmission of the pathogens to humans. Toxin production and virulent factors are often responsible for the pathogenesis of these pathogens. Foodborne zoonotic pathogens cause human infections that are typically characterized by gastrointestinal symptoms, including vomiting, nausea, abdominal cramps, diarrhea, body pain, and more severe health issues such as neurological diseases. Prevention of these pathogens in foods could be achieved by the implementation of standardized hazard analysis critical control point (HACCP), good hygiene, good manufacturing practices, good operational sanitation practices, and pasteurization procedures to enhance food safety. The increasing spread of multidrug resistance among zoonotic foodborne pathogenic microbial species is worrisome as this could lead to the emergence of entirely new pathogenic strains in the food chain. Therefore, the implementation of coordinated monitoring and surveillance systems in the food chain (from farm to fork) is highly recommended.
