The infection were caused by the O157:H7, the same strain of E. coli observed in the XL Foods safety investigation, which brings the total number of cases linked to XL Foods to three in B.C., the centre said in a news release Friday.
The centre said one of those people infected is an adult who was visiting Canada from outside the country and tested positive in the Vancouver Coastal Health Authority after consuming beef in both Alberta and B.C.
The person has returned home and is recovering, the release said. The individual's home country was not revealed.
The second person is an adult diagnosed in the Fraser Health Authority, which covers a large area immediately east of Vancouver.
This person consumed beef purchased in B.C. and an investigation into the source of the purchase is ongoing, the release said. That individual is also recovering from the effects of the infection.
The XL Foods plant in Brooks, Alta., was allowed to resume limited meat processing Thursday under the supervision of the Canadian Food Inspection Agency after a massive recall of beef products over E. coli concerns.
The recall of what grew to be a list of hundreds of products began in September.
A total of 15 people have been infected in Canada, the BCCDC release said.
