Used to be no gloves, but after visiting the TX Disposal System with MGs a few yrs ago, I wear gloves all the time when I'm digging in the dirt. At TGS they explained that everything goes into the various soil mixtures they carry. Everything includes road kill, among other unsavory by-products I'd never thought about. I had bought that soil for all my garden beds, from them and from another well known organic nursery.
I hope to have a vegetable garden next spring, but I'll use my own compost to fill the raised bed. No road kill for my veggies.
