South Carolina health inspectors are investigating an outbreak of Escherichia coli O157:H7 linked to a Mexican restaurant in Spartanburg.

New Brunswick media are reporting public health officials continue to seek the causes of two sets of E. coli outbreaks in New Brunswick - one in Miramichi and the other in the Saint John area.

Health officials in New Brunswick say they have some leads in their search for the source of an E. coli outbreak that they believe has left people ill in three communities. However, a spokeswoman for the Health Department said Saturday there's, “still no clear evidence of the source of the outbreak.”

Although nominally about epidemiological basics and evaluative techniques during an outbreak of foodborne illness, a new paper also provides some details – and investigative uncertainty -- during a 2008 outbreak of E. coli O157:H7 linked to raw milk cheese in Quebec (that’s in Canada).
