Abstract2:
Forty-seven species of flies have been reliably associated with filthy
conditions that might allow the spread of foodborne pathogens. These are categorized as
"filth flies." Of that 47, only 21 species represent a potential threat to human
health as scientifically proven causative agents of foodborne myiasis or as carriers of
enteropathogenic Escherichia coli, Salmonella, Shigella, and other foodborne pathogens.
These 21 species are categorized as "disease-causing flies" based on strict
scientific criteria. The criteria are association with E. coli, Salmonella, AND Shigella;
synanthropy; endophily; communicative behavior; attraction to both excrement and food
products; and recognition by authorities as a potential health hazard. Within Hazard
Analysis and Critical Control Point and other U.S. Food and Drug Administration regulatory
frameworks, disease-causing flies are contributing factors to the spread of foodborne
disease that require preventive and corrective actions as appropriate under Sanitation
Standard Operating Procedures, Good Manufacturing Practices, or pest control programs.
