A new performance audit by Kenya's Auditor General, Nancy Gathungu, reveals that the sale of expired, counterfeit, and unregistered pesticides continues to be a significant problem despite intensified enforcement by the Pest Control Products Board (PCPB).

• The quantity of illegal pesticides seized dramatically increased from 902 kilograms in 2021/22 to 28,617 kilograms in 2024/25.
• The PCPB is criticized for failing to revoke licenses of businesses convicted of selling illegal pesticides.
• Weak follow-up inspections, limited public awareness among farmers, and inadequate border surveillance contribute to the persistent issue.
