Delievered a load of '11 corn Friday afternoon to the local elevator.
What a joy this is going to be this year.
Every single load is getting a DNA test to check for Aflotoxin. Takes about 10 minutes. They have to grind it in a blender, wet it, bake it, then look for the red stripe on the test strip.
They are practicing on the old corn to get a hang of the procedure. Good thing there is a very short crop here in South Podunk Country.
10+ MINUTE WAIT after leaving the scale. One thing about it the pit will always have room. 20 parts per Billion is the threshold for rejection.

You take it home or what ever, but it is not dumped.
Might make this years crop shorter.
If you have aflotoxin and rejectable corn, DO NOT harvest it.
It will be deemed unfit and Zeroed out for crop insurance, If you harvest it and bin it, it will be measured and counted as production against your guarentee. Only combine a load or maybe even just enough for sample purposes till you know for sure it is OK.

This elevator grinds 150,000 bu a week for hogs and chickens and a little calf feed. As they have no way to identity preserve the crap from the good, so it all has to be good, The Torrance for young livestock is 20 PPB., that's right 20 parts per Billion for the most sensitive class of animal and that is their threshold to dump at any of their 7 locations.

You are right about the 20 level. What I should have said is if you have an aflotoxin issue is to not harvest till you know the severity of the issue. There are levels that will cost you $ if you harvest before knowing what you are dealing with. My guess is it is not going to be the issue it is hyped to be but there are always exceptions.
You are right about who takes the official sample BUT you can take your own for testing to see where you are at before you make that million dollar mistake and wind up with a completed harvest and unsaleable crop in the bin AND no insurance because of it.
Here locally there has been corn harvested with just a little over a 40 # test wt.

On Friday, I witnessed a field in southcentral Iowa that had so much aflatoxin, the Cargill plant in Eddyville rejected the load. Farmers say the aflatoxin test takes 15 minutes. This is going to slow up farmers that are trying to 'dump and go'.

If it's anything like the Vomitoxin or "DON" test they were running a couple years ago, it would take about a half hour till they could get your test run. Then if it didn't pass, they would run a second test while you sat in their "penalty box" waiting to see if you could unload. I saw readings from way over acceptable drop to almost nothing that came from the SAME SAMPLE! I don't know who designed the tests...but I don't think they're very accurate on a time sensitive basis like unloading trucks demands.
