Salmonella is a recognised hazard in chocolate because it

  • A.survives for long periods at low water activity
  • B.multiplies rapidly in the cocoa butter
  • C.is produced by the fermentation of cocoa beans
  • D.is destroyed only by freezing the product

Answer: A

The organism cannot grow in chocolate but persists in it for months, and the fat coating protects it from stomach acid, so a very small number of cells can cause illness. Several large outbreaks have been traced to chocolate for exactly this reason.
