DEATH CAMAS Near animal fatality Recently, we heard that a local horse owner experienced a near animal fatality due to feeding hay containing Death Camas- Toxicoscordion venenosum. What is Death Camas? A native plant to western parts of North America, from the lily family that contains a toxic chemical called zygacine. Young plants tend to be more toxic than older plants. It is most often found in dry areas of Western US. The bulb is often confused with edible wild onions – eating one or two bulbs can cause and all parts of the plant are poisonous. The only practical means of defense are 1) prohibit stock from using heavily infested areas, 2) avoid early turnouts; wait until ample amounts of good forage are available, 3) make sure the hay you’re feeding is free of weeds and possible poisonous plants. The horse owner had been feeding morning & evening while dark and was unaware of the contamination until a young horse became ill. Fortunately, her horse survived. She contacted the local hay grower to alert him of the Death Camas in the hay. Do you know where your hay comes from? Don’t be afraid to ask if it’s “weed-free”.
