PlantFunSoybean Toxic?
Raw soybean seeds contain phasin, a toxalbumin fully inactivated by 15-20 minutes of boiling at 100°C
Uncooked soybean consumption can cause favism, seizures, hemorrhagic gastroenteritis, and fatal outcomes, especially in livestock
Extra toxicity risk occurs if soybean extraction meal is mixed with mold-contaminated peanut extraction meal

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Induce vomiting if raw soybean ingestion occurred within 2 hours and the individual/animal is conscious
- • Administer activated charcoal to absorb remaining toxins if advised by a medical or veterinary professional
- • Avoid inducing vomiting if the individual/animal is seizing, unconscious, or has bloody diarrhea
Contact Vet Immediately
- • If raw soybean plant/seeds are ingested by any animal, especially horses, cattle, or pigs
- • If symptoms including seizures, bloody diarrhea, or severe abdominal pain develop post-ingestion
- • If exposure to mold-contaminated soybean/peanut feed meal is confirmed
Prevention
- • Always cook soybeans for 15-20 minutes at 100°C before human or animal consumption to destroy phasin
- • Do not feed raw soybean plant material or seeds to livestock or companion animals
- • Test livestock feed to ensure it is not mixed with moldy peanut extraction meal
Treatment & Prognosis
- • Digestive tract decontamination as clinically indicated
- • Symptomatic supportive care for seizures, dehydration, and gastrointestinal damage
- • Long-term monitoring for organ damage in severe cases
Professional Toxicology
• Phasin damages the gastrointestinal lining and red blood cells, leading to hemorrhagic symptoms and systemic toxicity
• Mold-contaminated mixed feed introduces additional mycotoxin exposure risk
