Why Is Ham Is a Common Vehicle for S

Why is ham is a common vehicle for S. aureus food poisoning?

A) S. aureus is part of the normal microbiota of cows, so is a frequent cause of S. aureus food poisoning.
B) Staphylococci are adapted to salty conditions and thrive with little competition on cured meats such as ham.
C) Staphylococci are able to act synergistically with the normal microbiota of pigs, creating toxins that result in food poisoning.
D) Ham is a particularly moist meat, so encourages the growth of the staphylococci, which can only survive on foods with a high aw.
E) Ham is an untreated raw meat. As such, it is prone to contamination by the staphylococci that thrive on meat, resulting in food poisoning.
