Abstract
Foodborne diseases are the most common causes of illness worldwide. Bacterial pathogens, including Staphylococcus aureus, are often involved in foodborne disease and pose a serious threat to human health. S. aureus is commonly found in humans and a variety of animal species. Staphylococcal enteric disease, specifically staphylococcal food poisoning (SFP), accounts for numerous gastrointestinal illnesses, through the contamination of food with its enterotoxins, and its major impact on human health imposes a heavy economic burden in society. Commonly, antibiotics and antimicrobials are used to treat SFP. However, a range of complications may arise with these treatments, impeding the control of S. aureus diseases specifically caused by methicillin-resistant S. aureus (MRSA). Natural alternative options to control S. aureus diseases, such as bacteriophages, plant-based antimicrobials, nanoparticle-based or light-based therapeutics, and probiotics, are promising in terms of overcoming these existing problems as they are environmentally friendly, abundant, unlikely to induce resistance in pathogens, cost-effective, and safe for human health. Recent findings have indicated that these alternatives may reduce the colonization and infection of major foodborne pathogens, including MRSA, which is crucial to overcome the spread of antibiotic resistance in S. aureus. This review focuses on the present scenario of S. aureus in foodborne disease, its economic importance and current interventions and, most importantly, the implications of natural antimicrobials, especially probiotics and synbiotics, as alternative antimicrobial means to combat pathogenic microorganisms particularly, S. aureus and MRSA.
