Salmonella and chocolate

Today's Guardian reports (in the third of three stories of interest that I saw at lunchtime!) that the "scare" over salmonella montevideo in chocolate is spreading, because the "crumb" that contained the bacteria has been used by other manufacturers. Here are some things to read about the story, or about the bug:

Today's Guardian
CDR Weekly (for 22 June 2006) (there are also links from the HPA home page, for S. montevideo, but they seem to me to lead to material about S. ajioba, which Saturday's Guardian is reporting about also: more details later!)
The Food Standards Agency website (this includes a list of products recalled by Cadbury's)
