|July 1, 1975
Summary
Dairy cows experienced acute poisoning, with significantly decreased cholinesterase activity and parathion detected in hair. Parathion spraying within the cowstable was identified as the probable cause, not winddrift.
Area of Science:
- Veterinary Toxicology
- Environmental Health
Context:
- Acute poisoning observed in a dairy cattle herd.
- Half the herd exhibited clinical signs of poisoning.
Purpose:
- Investigate the cause of acute poisoning in dairy cattle.
- Determine the source of parathion exposure.
Summary:
- Blood samples showed cholinesterase activity reduced to 10% of normal in affected cows.
- Parathion was identified in hair samples from all tested cows.
- Parathion residues were also found on cowstable walls, indicating direct exposure.
- Cholinesterase levels gradually recovered over 3.5 months.
Impact:
- Identified direct parathion exposure within the cowstable as the likely cause of poisoning.
- Ruled out winddrift as a probable source of contamination.
- Provides insights into parathion toxicity and environmental contamination in livestock settings.
