Sample. Labwork. Report. Easy enough.
LOL, if each eggplant weighed two pounds that would be over 5000 individual eggplants. What are they gonna do, stick a needle in each one?
You know what we say around here about bringing in huge amounts of military age muslims without figuring out a way to check them out...even if only 9% of them want to do us harm...it is like a jar of jellybeans to give to your kids, and only 9% of the individual jellybeans have cyanide in them!
Do you remember the incredible luck US customs had with a container of grapes from Chile back when we were having trade issues with them? The found the one grape in an entire shipping container that had been injected with cyanide.
An amazing thing, a grape injected with cyanide in Chile, arrived in the US un-shriveled and un-blemished and just happened to be one customs inspected.
Chile decided to be reasonable and do what we wanted...
The veggies would be rotted before the lab work on 5.5 tons of veggies was completed.
