- cloxacillin.
- dicloxacillin.
- flucloxacillin.
How is Staphylococcus aureus responsible for food poisoning?
S. aureus carriage rate varies with geographic location, age, sex, and body niches. In addition to staphylococcal infections, S. aureus is also responsible for food poisoning due to oral intake of enterotoxins present in foods ( Johler et al., 2015a ).

What foods can cause Staphylococcus aureus food poisoning?
