Analysis of factors affecting the technical efficiency of cocoa producers in the south-west region of Cameroon

Contamination of Foods from Cameroon with Residues of 20 Halogenated Pesticides, and Health Risk of Adult Human Dietary Exposure

“…These results reflect the poor knowledge of farmers on pesticides and in practices of pesticide usage in the different parts of the country, demonstrated in previous reports [ 14 , 16 , 17 , 21 , 22 , 23 , 24 , 25 ]. Our findings also indicate that the usage of halogenated pesticides in Cameroon may not vary in the different agroecology areas of the countries.…”

“…Organochlorines such as DDT have been extensively used in Cameroon for both malaria vector control and agricultural purposes in the 1950s through to the 1960s before being replaced by pyrethroids like cypermethrin and deltamethrin [ 19 , 20 ]. A number of factors that can contribute to high exposure of consumers such as intensive utilization by farmers and limited knowledge about pesticide use are reported in Cameroon [ 14 , 16 , 17 , 18 , 21 , 22 , 23 , 24 , 25 ]. There is also a high number and different types of obsolete pesticides accumulated over the years in the country, among which are many halogenated compounds [ 26 , 27 ].…”

Monitoring and dietary risk assessment of 81 pesticide residues in 11 local agricultural products from the 3 largest cities of Cameroon

“…A recent study found that the contamination of organophosphate residues in composite foods from Cameroon varied with the location (Douala vs Garoua) and with the season of sample collection (rainy vs dry season) (Ingenbleek et al, 2019). These results reflect the differences in the knowledge of farmers on pesticides, and in practices of pesticide usage in the different parts of the country presented in previous reports (Gama et al, 2016;Kenko et al, 2017;Manfo et al, 2012;Nchare, 2007;Jean Sonchieu et al, 2010;Tandi et al, 2014;D. Tarla et al, 2015;Tayoh et al, 2016).…”

“…Reports show that numerous factors contributing in possible high exposure of consumers such as intensive utilisation and limited knowledge about pesticide use, are found in Cameroon. In fact, because farmers did not receive sufficient training on pesticide application and proper assistance from agricultural extension agents, inappropriate use of pesticides by Cameroonian farmers have been documented in many studies from different parts of the country (Gama, Folorunso, & Adeola, 2016;Kenko et al, 2017;Manfo et al, 2012;Nchare, 2007;Jean Sonchieu, Benoit Ngassoum, Bosco Tchatchueng, Srivastava, & Srivastava, 2010;Jean Sonchieu, Fointama, Akono, & Serri, 2019;Tandi, Wook, Shendeh, Eko, & Afoh, 2014;D. Tarla et al, 2015;Tayoh, Kiyo, & Nkemnyi, 2016).…”

Evaluation of 99 Pesticide Residues in Major Agricultural Products from the Western Highlands Zone of Cameroon Using QuEChERS Method Extraction and LC-MS/MS and GC-ECD Analyses

“…Recent studies [4] suggested that the male farmers of Djutitsa in West Cameroon are exposed to agro-pesticides due to improper personal protective equipment (PPE), and this exposure may impair their reproductive function. Inappropriate use of pesticides by Cameroonian farmers has been documented in many studies from different parts of the country [4,7,10,11,12,13]. This was because farmers did not receive sufficient training on pesticide application and proper assistance from agricultural extension agents [7], which could result in high levels of pesticide residues in local foods.…”
