Staphylococcus aureus in food safety: antimicrobial resistance, detection technologies, and future perspectives

Staphylococcus aureus is an important zoonotic pathogen associated with severe infections in both humans and animals. Food contaminated with staphylococcal enterotoxins can lead to food poisoning, characterized by symptoms such as nausea, vomiting, and diarrhea. This review examines a broad spectrum of S. aureus and its enterotoxins in food, with particular attention to the implications for public health. While the review includes a focus on methicillin-resistant S. aureus (MRSA) in foodborne illnesses, it also discusses other challenges posed by this pathogen, including antimicrobial resistance and its role in food contamination. The review highlights strategies for prevention and control, such as hygiene practices, temperature management, and advancements in detection technologies. Furthermore, innovations in natural antimicrobial agents and thermal/non-thermal technologies are improving food safety without compromising quality. Despite advancements, challenges remain in combating S. aureus contamination. Ongoing research focuses on developing new technologies to deactivate the pathogen and its toxins. In conclusion, addressing these challenges requires sustained efforts to enhance food safety protocols, alongside identifying future research needs in technology development.
