There's a new warning about flour from a provincial health agency.

The B.C. Centre for Disease Control has revealed that six more people have been infected with E. coli O121. This strain was also detected between February and April.  

"A sample of flour from one of the ill people was tested by the BCCDC Public Health Laboratory," the BCCDC said in a news release. "The flour was positive for the same strain of E. coli O121 as seen in all the illnesses."

It hasn't been confirmed that the five other cases are linked to the same flour.

"E. coli infection (which used to be called hamburger disease) can be a serious illness causing bloody diarrhea (hemorrhagic colitis), kidney failure and death," the BCCDC stated on its website.

The agency is recommending that consumers throw out any packages of Rogers All Purpose Flour in 10-kilogram bags with the lot number MFD 17 Jan 19 C. It was sold in Costco stores.

A national recall of this product was announced in early April by the Canadian Food Inspection Agency.

"The outbreak serves as a reminder that it is not safe to taste or eat raw dough, batter or foods containing raw or undercooked flour (e.g. raw frozen pastries or doughs) regardless of the type of flour used, and that surfaces that come into contact with raw flour should be thoroughly washed as flour can be contaminated with harmful bacteria," the BCCDC stated. "Although this outbreak is occurring at the same time as a national outbreak involving a different strain of E. coli O121 that has been linked to various flours and flour products, it is unclear whether there is a link between the two outbreaks."
