Public health implications of microbial contamination in registered slaughterhouses: A case study from La Union, Philippines

Meat safety is a public health concern and is significantly influenced by slaughterhouse hygiene, handling and sanitation. This study was conducted to assess the microbial quality of meat and identify hygiene practices in selected slaughterhouses in the Province of La Union from January 28 to February 28, 2025. Swab samples from meat contact surfaces including carcasses were collected and analyzed for microbial contamination for potential pathogens including Aerobic Plate Counts (APC) of Staphylococcus aureus, Escherichia coli, Salmonella spp., and Coliforms were prepared. Results revealed varying levels of microbial contamination, with some samples exceeding acceptable safety limits, indicating potential risks to public health. Poor sanitation, improper handling practices, and inadequate facilities contributed in the contamination levels. The study highlights the need for stricter enforcement of hygiene protocols, improved slaughterhouse infrastructure, and regular microbial monitoring to ensure meat safety.
