Stay Vigilant

Is a rolling basket truck a vector for pathogens?You bet. Dirty used floor mats go into the same filthy basket truck as clean mats. Then rolled into your facility. This a breach in your biosecurity.

Be prepared for the delivery person and don't let them in your grow.

1. Roll up your mats and have them at the pickup site.
2. Use your own rolling plastic bin to carry clean mats back inside.
3. Distribute the floor mats and sanitize your bin.
4. Slip the delivery person a few bucks to see if he'll come to your facility first, if you're in a complex full of other growers.

A siege mentality is as necessary as good chemistry, processes, and tools to pass all your microbe tests.
