Probably not. Ricin is toxic.
Wood Green ricin plot happened in 2003.
Ricin
The production of ricin is a low-tech endeavor requiring little time or funding.
Hard to detect.but still it is possible. Doctors guess it by Symptom. There is a Special test designed to detect Ricin!
It doesn't "become" toxic, it starts out that way.
The active poison in the castor bean is ricin, a deadly water-soluble protein called a lectin.
Initial symptoms of ricin poisoning by inhalation may occur as early as 4- 8 hours and as late as 24 hours after exposure. Following ingestion of ricin, initial symptoms typically occur in less than 10 hoursInhalation: Within a few hours of inhaling significant amounts of ricin, the likely symptoms would be respiratory distress (difficulty breathing), fever, cough, nausea, and tightness in the chest. Heavy sweating may follow as well as fluid building up in the lungs (pulmonary edema). This would make breathing even more difficult, and the skin might turn blue. Excess fluid in the lungs would be diagnosed by x-ray or by listening to the chest with a stethoscope. Finally, low blood pressure and respiratory failure may occur, leading to death. In cases of known exposure to ricin, people having respiratory symptoms should seek medical care.Ingestion: If someone swallows a significant amount of ricin, he or she would likely develop vomiting and diarrhea that may become bloody. Severe dehydration may be the result, followed by low blood pressure. Other signs or symptoms may include seizures, and blood in the urine. Within several days, the person's liver, spleen, and kidneys might stop working, and the person could die.Skin and eye exposure: Ricin is unlikely to be absorbed through normal skin. Contact with ricin powders or products may cause redness and pain of the skin and the eyes. However, if you touch ricin that is on your skin and then eat food with your hands or put your hands in your mouth, you may ingest some.Death from ricin poisoning could take place within 36 to 72 hours of exposure, depending on the route of exposure (inhalation, ingestion, or injection) and the dose received.Copied from CDC website

Ricin is a toxic substance that comes from the pressed leaves of the castor beans. If the beans of the castor plant are eaten, it could cause harm from the ricin that is formed by the action. Ricin can cause harm through ingestion, inhalation or through contact with the skin.
