I'm sorry, and this is great, but let me jump in here with a supplementary question.
I think you're right. It's almost impossible to 100% guarantee zero contamination all the time. How is that handled now? Is it very subjective, whereby someone sees a bit of cross-contamination and says we're not going to worry about it this time, but next time we might, or another country might worry about it and that's what injects uncertainty into the supply chain, the fact that there are different answers depending on the judgment of a regulatory body or an inspector, depending on a number of different factors that aren't necessarily in black and white?
