Is Butterweed Poisonous? The ULTIMATE US Safety Guide

Senecio glabellus, commonly known as butterweed, presents a significant concern regarding its toxicity, especially within agricultural settings across the Southeastern United States. The USDA identifies butterweed as a plant containing pyrrolizidine alkaloids, compounds known to cause liver damage in livestock. The question of is butterweed poisonous is therefore not simply academic but directly relevant to animal health and, indirectly, human food safety. The presence of these alkaloids requires diligent management strategies, often informed by research conducted by organizations such as the American Society for the Prevention of Cruelty to Animals (ASPCA). Correct identification of butterweed using field guides and resources from poison control centers is the first critical step in mitigating potential risks from exposure.
