Yes. It's root cause analysis: you do sampling, let's say, of the environment, to find out where it is, and once you find that it is there, you take steps to eliminate it.
We've made a number of changes to the overall policy from the previous 2004 policy. I can give you just a few examples.
We've strengthened the end-product compliance criteria in terms of the numbers of organisms we allow in a food; we've actually strengthened that.
We've also stated, as I mentioned, that an environmental monitoring program should be used in all plants. We've also brought up the whole issue of trend analysis, so that a plant is not just doing tests and then putting the results in the drawer but is looking at the whole continuum of results over a period of time, as with trend analysis data. That's what companies have already started to do.
It also very importantly lists and encourages the use of post-processing inhibitors. For example, if you put a chemical in that can inhibit the growth of the organism, basically you're reducing your risk to near zero. We're encouraging companies to use technology, such as adding chemicals, maybe using processes such as ultra-high pressure, which a number of companies have already started to use. This high pressure can burst a cell and inactivate cells with listeria monocytogenes.
We also have an increased focus on outreach with the federal-provincial community to increase awareness of the risks of food-borne listeriosis. We've worked very closely with the CFIA on the policy as well. We've had excellent feedback from them. We have had excellent feedback also from the provinces.
So we feel we've come up with an improved policy and we have already had excellent comments back from industry as well on our efforts.
