Summary

A family experienced a foodborne outbreak of cholinergic syndrome due to accidental organophosphate poisoning from fensulfothion. Prompt recognition of non-bacterial causes is crucial for effective treatment.

Area of Science:

  • Toxicology
  • Environmental Health
  • Clinical Medicine

Background:

  • Foodborne outbreaks are commonly attributed to bacterial or viral pathogens.
  • Organophosphate pesticides are widely used, posing risks for accidental poisoning.
  • Cholinergic syndrome symptoms can mimic other serious conditions.

Observation:

  • Three family members presented with nausea, vomiting, abdominal pain, weakness, and decreased consciousness.
  • Two patients experienced bradycardia, hypotension, and seizures.
  • Initial treatment for botulism was ineffective.

Findings:

  • The outbreak was caused by accidental organophosphate (fensulfothion) poisoning.
  • Fensulfothion, an insecticide, was identified as the source of the poisoning.
  • The clinical presentation was consistent with a severe cholinergic crisis.

Implications:

  • Physicians need to consider non-bacterial causes, such as pesticide poisoning, in foodborne outbreaks.
  • Early identification of organophosphate poisoning is vital for specific and timely treatment.
  • Public health awareness regarding pesticide risks in food is essential.
