Convulsions caused by endrin poisoning in Pakistan

Area of Science:

• Environmental toxicology
• Public health
• Neurotoxicology

Background:

• Endrin, an organochlorine insecticide, poses significant health risks.
• Previous outbreaks have been linked to endrin exposure.

Purpose of the Study:

• To investigate an outbreak of acute convulsions in Pakistan.
• To identify the causative agent and assess its public health impact.

Main Methods:

• Epidemiological survey of affected villages.
• Clinical assessment of patients.
• Toxicological analysis of blood and food samples.

Main Results:

• 152 cases of endrin poisoning, primarily affecting children aged 1-9 years (70%).
• A mortality rate of 9.8% was observed.
• Endrin detected in patient blood and a sugar sample, confirming contamination.

Conclusions:

• Endrin poisoning caused a severe outbreak of convulsions in Pakistan.
• The high toxicity and outbreak potential necessitate prohibiting endrin in agriculture.
