What is it about?

The cocoa plant is prone to disease and pests and therefore relies heavily on pesticides for cultivation. Here, we use a systematic literature review to quantify the extent of research on residues of pesticides used in cocoa cultivation in honey.

Why is it important?

In 81% of the 104 studies examined for this analysis, 169 distinct compounds were detected. Imidacloprid was the most frequently detected pesticide, making neonicotinoids the most frequently found class of pesticides overall.


I found it quite surprising that only 19% of the 104 studies reviewed were carried out in cocoa-producing countries! Priority needs to be given to countries that produce cocoa to help understand the potential impact of pesticide residues linked with cocoa cultivation on bees and bee products.
