No solution to inform

Whereas some dairies try to make use of farms that don’t use the expansion hormone, there’s no take a look at or third-party certification.

The one factor Canadians can do, is search for the “100% Canadian” brand on their dairy merchandise — which has prompted each Canadian firms and shoppers to speak about “shopping for Canadian.”
