       * at typical fridge temperatures (≤ 4 °C), S. aureus growth is effectively halted or becomes extremely slow, and enterotoxin production does not occur at these temperatures, nevertheless most would recommend sliced meats such as ham is consumed within 3-5 days when kept in a fridge and there has not been a "abuse period"       * at typical fridge temperatures (≤ 4 °C), S. aureus growth is effectively halted or becomes extremely slow, and enterotoxin production does not occur at these temperatures, nevertheless most would recommend sliced meats such as ham is consumed within 3-5 days when kept in a fridge and there has not been a "abuse period"
       *risk of enterotoxin food poisoning increases sharply if slices sit at room temperature (or warmer, e.g. buffet, car, esky at ambient) for several hours, especially if there is hand contact from a colonised handler, then are returned to the fridge; that abuse period is when toxin is formed and, once formed, the toxin is not destroyed by reheating or by refrigeration.       *risk of enterotoxin food poisoning increases sharply if slices sit at room temperature (or warmer, e.g. buffet, car, esky at ambient) for several hours, especially if there is hand contact from a colonised handler, then are returned to the fridge; that abuse period is when toxin is formed and, once formed, the toxin is not destroyed by reheating or by refrigeration.
