Agriculture Ministry Warns Public Over Poisonous Rubber Seeds Mixed With Beans

The Ministry of Agriculture, Animal Industry and Fisheries (MAAIF) has issued an urgent food safety warning to consumers across Uganda. The alert follows verified complaints and evidence regarding poisonous rubber tree seeds being mixed with beans sold in local markets, with cases particularly noted in Agago District.

According to the ministry, the scientifically named Hevea brasiliensis seeds are entirely inedible. They contain dangerous compounds known as cyanogenic glycosides, which release cyanide and lead to severe poisoning when consumed. Symptoms of ingestion—whether the seeds are eaten raw or cooked alongside beans—include intense stomach pain, vomiting, dizziness, headaches, physical weakness, and diarrhoea. Children face heightened vulnerability, and farm animals such as pigs and chickens can die after consuming large quantities.

To safeguard households, MAAIF has urged shoppers to thoroughly inspect their dry beans before making a purchase. While typical beans feature a flat or kidney-like shape, rubber tree seeds are easily identified by a round, marble-like appearance, a shiny grey-white color, and distinctive dark brown or black spots and stripes. They also feature a small white attachment mark where they once connected to the pod.

Consumers are advised to spread beans across a flat surface or tray to sort out any mottled, round seeds, stones, and broken pieces before washing them multiple times with clean water. Households that remain uncertain about food safety are encouraged to consult agricultural extension workers or local health centers.

Anyone who suspects they have ingested the toxic seeds should seek immediate medical assistance at the nearest hospital, ensuring they bring a sample of the suspected seeds to aid medical staff. Meanwhile, traders have been instructed to refrain from storing food produce in sacks previously used for non-food items like rubber seeds. Market leaders, agricultural police, and local councils have also been called upon to step up inspections to protect community health.
