Before August, the process, as recommended in global best practice, was to respond to each product-positive sample by remediating the site. This means aggressive sanitation, cleaning, and monitoring of the site. Our internal policy was to get three consecutive negatives after a positive on a food contact surface. So before August, this was what the Maple Leaf company did in that facility.
Today, however, we take a much more holistic approach to every positive finding. We dig deeper, and we're more rigorous in our evaluation of that root cause. We look for patterns in the data. We ask whether that particular site on that particular line has been positive in the past, and if so, we look for a linkage. What can we learn from the historical data? These are the types of things that are different today than they were then. We maintain the concept of following every positive site with consecutive negatives until we're certain that the product passing across that line is safe.
