Thank you. It's a very good question.
With respect to traceability, there's a push for things like blockchain. However, without verification testing along the supply chain, you're really only tracing the movement of packages and not what's actually in them. We've developed tools. For example, for a business dealing in large volumes of a single commodity, you can have a hand-held instrument with a PCR test at point of detection and can ask, “Is my cod, cod?” If it's not, then it would need to go to a lab for full-blown sequencing to determine what it is.
In terms of quality control, if you're taking possession of, say, a two-tonne shipping container and something declared to be red snapper, then it is possible to confirm that it's red snapper on site, in real time, with PCR tests today. It's just like we're doing with rapid tests for COVID.
