Acute toxicosis in cattle sprayed with endosulfan

Area of Science:

• Veterinary Toxicology
• Environmental Health
• Agricultural Science

Background:

• Organochlorine insecticides, such as endosulfan, are potent pesticides used for insect control.
• Off-label use of pesticides in livestock poses significant risks to animal health and food safety.
• Endosulfan is not approved for use in cattle, yet was applied for lice control.

Observation:

• Two cattle experienced fatal acute toxicosis following topical application of endosulfan.
• Three additional cattle exhibited severe illness but recovered with supportive care.
• Treatment involved decontamination and interrupting enterohepatic circulation to manage insecticide exposure.

Findings:

• Off-label application of endosulfan resulted in acute, severe poisoning in cattle.
• The cases demonstrate a clear link between unapproved insecticide use and adverse health outcomes in livestock.
• Successful intervention included symptomatic treatment and measures to prevent further absorption.

Implications:

• Veterinary and agricultural communities must adhere to pesticide labeling and regulatory guidelines.
• Off-label pesticide use can lead to illegal residues in animal tissues and milk, posing public health concerns.
• Strict enforcement and education are crucial to prevent toxicosis and ensure food safety in livestock production.
