I'm always concerned about zero tolerance policies because when you're mechanically processing agricultural products, you can never guarantee a zero tolerance, but a properly regulated tolerance. There are ways to ensure that your food handling system and your loading of the product into containers is in a centre to comply with legislation.
The bulk grain handling system is more at risk than a food safety control containerized shipment environment. This is where I see the big opportunity for Canada. It is in processed products that are in identity preserved containers for distribution.
