ABSTRACT
Pest and disease have been the major causes of low cocoa production worldwide and the use of chemicals in the form of pesticides is one of the main ways of mitigating their undesirable outcome. However, inappropriate application of pesticides does not only affect the quality of cocoa bean products and the wellbeing of consumers of such products but can also damage the natural flora and fauna in the environment. Hence the reason why evaluating the concentrations of pesticide residues is necessary in establishing the quality of a cocoa. The goal of this study was therefore to determine the concentrations and distribution of specific pesticide residues in cocoa beans from the six cocoa growing regions of Ghana. Three classes of pesticides were tested for in cocoa beans obtained from seventeen (17) districts in the Brong Ahafo, Eastern, Central, Western North, Ashanti and Western South cocoa growing regions of Ghana. These were the neonicotinoids (Thiamethoxam, Clothianidin, Imidacloprid and Acetamiprid); the synthetic pyrethroids (Cypermethrin, Deltamethrin, Fenvalerate, Lambda Cyhalothrin and Permethrin) and the organophosphorous compound Chlorpyrifos. Pesticide residue analyses were done separately on the whole unshelled beans, the nibs and the shells using a GC/ECD for the synthetic pyrethroids and organophosphorous compound and a QqQ-LC/MS for the neonicotinoids. The results obtained showed that the mean concentrations of the neonicotinoids in all the three matrices ranged from
