Although the Vancouver Coastal Health authority had identified a cluster of E. coli infections as early as last Thursday, no public health warning was issued, said spokeswoman Anna Marie D’Angelo.

All 13 cases that have presented so far are thought to be related to exposure to the the PNE petting zoo.

The Vancouver Sun reports that B.C.’s Medical Health Officer Dr. John Carsley, said,

“We were suspicious on Thursday when two cases were reported, then there were more on Friday. … “We wrestle very seriously with this issue of whether to do a public alert or not. It depends very much on the outbreak, and if there is a continued risk out there.”

The family of 14-month-old Jacklyn Simpson (above, right, photo from Vancouver Sun), who was stricken with the illness after visiting the petting zoo, believes that had they known about the outbreak, they might have been able to get help earlier.

That’s one of the reasons to issue public alerts – so additional illnesses can be prevented. E. coli O157 also spreads easily from person-to-person so public warnings may help reduce additional transmissions.

And it would be helpful if public health types would clearly articulate why they go public about foodborne illness outbreaks and when. Saying, "we wrestle with it,” does not enhance public confidence. Or prevent additional illnesses.
