Gillespie Livestock
Screwworm Statement & Educational Material
Statement: Gillespie Livestock is here to take care of consignors and buyers like every other week. We work for you and will not operate under fear as such state has no value, we have conquered this enemy before. Feeding the masses has always been on the back of the American rancher and farmer. A view from our 75-year-old catwalk will show a resilient industry which has withstood droughts, trade wars, epidemics, activists, and last but not least our own government. We wake up to a dawn of a war we have fought before; arguably, lessons should have been learned. Now, with history on our side, we are in a battle we know how to win. We are ready to pull up our sleeves and go to work. Unless in an infected zone, it will be business as usual.To all consumers, this is NOT a food safety issue…………..Eat more beef, lamb, and goat! God Bless the rancher.
