Current pathogenic Escherichia coli foodborne outbreak cases and therapy development

Area of Science:

• Food safety and public health
• Microbiology
• Epidemiology

Background:

• Food contamination by pathogenic microorganisms, particularly E. coli, poses significant global public health and economic challenges.
• E. coli contamination can occur at any stage of the food supply chain, originating from environmental, animal, or human sources.
• Specific strains like E. coli O157 and O104 are common causes of foodborne illness, even in developed nations.

Purpose of the Study:

• To review and analyze global foodborne E. coli contamination cases over the past decade.
• To elucidate the infection mechanisms and symptoms of major diarrheagenic E. coli pathotypes.
• To discuss current advancements in controlling and preventing bacterial food contamination.

Main Methods:

• Systematic review of worldwide reports on foodborne E. coli contamination cases from the last 10 years.
• Categorization and description of five key diarrheagenic E. coli pathotypes: enteropathogenic E. coli (EPEC), Shiga toxin-producing E. coli/enterohemorrhagic E. coli (STEC/EHEC), Shigella/enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and enterotoxigenic E. coli (ETEC).
• Analysis of foodborne outbreak data linked to E. coli in various food products.

Main Results:

• Identification of prevalent E. coli pathotypes responsible for foodborne illnesses.
• Documentation of foodborne outbreak cases associated with E. coli contamination in natural foods and food products.
• Summary of the infection characteristics and symptoms for major E. coli pathotypes.

Conclusions:

• Understanding E. coli pathotypes and outbreak patterns is crucial for effective food safety interventions.
• Ongoing research and technological advancements are vital for developing robust strategies to prevent and control bacterial food contamination.
• Implementing comprehensive measures across the farm-to-table continuum is essential to mitigate the risks associated with foodborne E. coli.
