Black mustard Toxic?
All parts of the plant are toxic, especially mature seeds, containing SMCO and glucosinolates
Glucosinolates are not inactivated by drying, while SMCO is inactivated via drying or ensiling
Poisoning typically impacts the gastrointestinal, respiratory, nervous, or urinary systems

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Remove all remaining plant material from the mouth and surrounding area to stop further ingestion
- • Induce vomiting only if explicitly advised by a medical or veterinary professional, for alert individuals that ingested the plant within 10 minutes
- • Avoid administering food, water, or home remedies unless directed by a healthcare provider
Contact Vet Immediately
- • Any symptoms of poisoning (salivation, diarrhea, difficulty breathing, disorientation, bloody urine) appear after exposure
- • Large quantities of the plant or its seeds are ingested by any animal or human
- • An individual with pre-existing gastrointestinal or respiratory conditions ingests the plant
Prevention
- • Do not feed black mustard or its press residues to livestock, as this practice is prohibited
- • Only feed green rapeseed to livestock prior to the flowering stage, and avoid feeding rapeseed cake alongside other Brassicaceae plants
- • Inspect livestock feed regularly to remove contamination with black mustard plant material or seeds
Treatment & Prognosis
- • Perform appropriate decontamination procedures based on the exposure route and time since ingestion
- • Administer targeted symptomatic and supportive care for the presenting symptoms (e.g. gastrointestinal support, respiratory support, fluid therapy)
- • Follow standard emergency toxicity treatment protocols as guided by a qualified medical or veterinary professional
Professional Toxicology
• SMCO (the anemia factor) is inactivated by drying or ensiling, but can cause anemia if consumed in its active form
• Glucosinolates are converted to toxic derivatives (isothiocyanates, nitriles, thiocyanates) when the plant is damaged or processed by rumen flora, and are not inactivated by drying
• Toxic metabolites irritate epithelial tissues and disrupt normal function across multiple body systems
