Please see the following responses to the questions posed in the post
E. COLI EHEC - CANADA (04): O121, FLOUR (March 29, 2017):

There are 25 cases of _E. coli_ O121 under investigation. A sample of
Robin Hood flour was collected from one case's home. The sample tested
positive for _E. coli_ O121 and had matching PFGE to the clinical
cases. Subsequently, a sample of Robin Hood flour collected from a
retail location also tested positive for _E. coli_ O121. Several cases
reported contact with Robin Hood flour. The investigation is ongoing
and it is possible that additional products linked to the outbreak
investigation may be identified.

Isolates from the 2016 US outbreak have been compared to the current
outbreak in Canada by whole genome sequencing (via PulseNet
International); the Canadian outbreak strain is not similar to the US
outbreak. Comparisons will continue to be made on an ongoing basis
throughout the outbreak investigation in Canada.
