Recently 2 horses have died because of a virus or bacteria that comes from possum manure. The horses were from 2 different places. My Dad is concerned about my horses. Have you ever of this. I have one horse on a pasture/lot, which was and is always for the horses, minimal cattle usage. I have my other horse in a cattle lot, the cattle were taken out in late spring and weeds and grasses have grown in the lot so she hasn't been kept in just dirt. I'm not too worried but maybe I should be. I was wanting to know if anyone else had ever heard of that and if they could enlighten me a little more.
