Resistance beyond the plate: heavy metal, disinfectant, and antibiotic resistance in foodborne Staphylococcus aureus isolates.

ABSTRACT: Staphylococcus aureus is a major foodborne pathogen capable of developing resistance to multiple antimicrobial agents, including antibiotics, disinfectants, and heavy metals. This study investigated 63 S. aureus isolates recovered from poultry products, meat cuts, and processed or ready-to-eat foods for their resistance to selected disinfectants [benzalkonium chloride (BC), cetylpyridinium chloride (CPC), triclosan (TCS)] and heavy metals [zinc (Zn), nickel (Ni), mercury (Hg), copper (Cu), cadmium (Cd), lead (Pb), cobalt (Co)]. The isolates from processed and ready-to-eat foods exhibited significantly higher resistance scores to antibiotics, disinfectants, and heavy metals compared to those from meat and poultry (P < .001). Notably, 45% of isolates from processed foods were resistant to 8
