| Summary: | <b>Background/objectives</b>: Antibiotic-resistant <i>Staphylococcus aureus</i> poses a significant risk to food safety and public health, particularly through the consumption of contaminated seafood. This study aimed to assess the presence and antibiotic resistance of <i>S. aureus</i> in seafood sold in the Tri-City area of Poland, addressing a knowledge gap regarding the region. <b>Methods</b>: Seafood samples (<i>n</i> = 89) were categorized according to their origin: domestic—Poland (PL), European countries (ECs), and Asian countries (ACs). <i>S. aureus</i> was isolated using ISO 6888-1 methods, and antimicrobial susceptibility testing was conducted against three antibiotics: erythromycin, clindamycin, and gentamicin, following CLSI guidelines. <b>Results</b>: Of the 89 samples, 68.5% were contaminated with <i>S. aureus</i>. The highest resistance rates were found for erythromycin (30.5%), with gentamicin showing the lowest resistance (8.3%).No significant correlation (<i>p</i> > 0.05) was found between resistance patterns and fish origin or processing level. <b>Conclusions</b>: The results of this study highlight the widespread occurrence of <i>Staphylococcus aureus</i> in fish sold in the Tri-City area, with a notable prevalence of antibiotic-resistant strains. |
