You're absolutely right that a test is being developed to be able to assess whether chicken meat, the broiler meat, is spent fowl, as declared. Generally it should be the case, but there's always a risk of abuse. This is why the Government of Canada, working closely with Brock University, as well as with the Chicken Farmers of Canada, is working on developing a test.
Such a test, however, needs to be robust to be used by the Canada Border Services Agency, which would be responsible for following a risk management approach. That's where the efforts are taking place right now.
But we are working as diligently as possible to ensure any tests sustain the robustness expected by our border services agency.
