Houseflies (Musca domestica) are synanthropic insects that are frequently found at open waste disposal facilities, important in the spread of parasites and harmful microorganisms. The perfect breeding and feeding conditions (warm temperature, moisture, abundant organic matter) found in these settings make it easier for disease-causing organisms to be acquired and spread. The significance of houseflies for public health is highlighted in this abstract, which examines the microbial and parasite dynamics of houseflies linked to open waste dumpsites. Numerous bacterial pathogens, such as Salmonella spp., Shigella spp., Staphylococcus aureus, Vibrio spp., Escherichia coli, Fungi, and antimicrobial-resistant strains, are routinely found in houseflies collected from dumpsites, according to studies. Parasites of medical significance, including Ascaris lumbricoides, Trichuris trichiura, Giardia lamblia, Entamoeba histolytica, and Taenia “spp”., have been identified from the gut contents and external body surfaces of houseflies. Seasonal variations, temperature, humidity, waste composition, and sanitation techniques all have an impact on the dynamics of microbial and parasite carriage. Particularly in low-income areas with inadequate waste treatment, high microbial and parasite load linked to houseflies from open dumpsites highlights their importance in the epidemiology of diarrheal illnesses and other enteric infections. Houseflies constitute a threat to public health in these environments, thus effective waste management, environmental sanitation, and fly control techniques are crucial. Appropriate environmental sanitation and improved waste management including waste segregation, routine disposal, dumpsite covering, and removal of organic breeding substrates can significantly decrease housefly populations and pathogen transmission. Integrated Pest Management (IPM), combining mechanical traps, biological agents, environmental control, and targeted insecticide use, is recommended. Future research should prioritize long-term surveillance of antimicrobial resistance patterns in housefly populations, especially in resource-limited regions with open dumpsites. More study should also focus on employing advanced molecular techniques to track resistance genes and determine transmission pathways between waste dumpsites, animals, and humans.
