Which of the following is a common sign of ricin poisoning?

1. Chronic fatigue and headaches

2. High fever and rashes

3. Severe vomiting and diarrhea with severe abdominal pain

4. Loss of vision and respiratory distress

The correct answer is: Severe vomiting and diarrhea with severe abdominal pain

Severe vomiting and diarrhea with severe abdominal pain is a common sign of ricin poisoning because ricin acts as a potent toxin that disrupts cellular protein synthesis. When ingested or inhaled, ricin can lead to gastrointestinal disturbances. The toxin provokes a strong inflammatory response in the intestines, resulting in symptoms that include severe abdominal pain, vomiting, and profuse diarrhea. These symptoms often arise within hours of exposure and can lead to dehydration and additional complications if not promptly treated. Understanding the nature of ricin as a highly toxic compound helps to distinguish its effects from those of other poisons, as it primarily targets the gastrointestinal system when ingested. This knowledge is crucial for recognizing the signs of poisoning and initiating appropriate medical intervention.
