Re: round-up pro

Yes. The first hint we had was that gardeners were calling in to the Extension Office saying that the only thing that was growing in their garden was corn. Every other vegetable was going belly up shortly after planting or transplanting. We assumed that the first couple of people had used a weed and feed, instead of plain fertilizer, but it turned out they were all organic or mostly organic growers.
Corn is a grass, of course, so it wasn't bothered by the Picloram. It took some sleuthing to determine the common denominator.
You'd probably be safe if the animals were getting Alfalfa hay exclusively. Alfalfa, being a Legume, is sensitive to the Picloram so it isn't used in Alfalfa fields.

So you need to make sure you have organic manure even! Good grief. I never would have thought of that.

Betsy,

The Glyphosate warning for tomatoes was out at least 9 years ago, maybe
longer (I'm figuring out how long it's been since I worked for the local
Extension Service before I went to work at the state level.)

The Seattle compost problem was because of an herbicide used on lawns and
fields -  Clopyralid. It can persist for years.

Picloram is a problem in manure from cattle or horses that have eaten feed from pastures or fields treated with Picloram, too. We first found out about that doozy in the mid-90's.
