nairobi's markets (1)


Measures to monitor meat substitution are in place in many developed countries, however, information about similar efforts in sub-Saharan Africa is sparse. Kenyan researchers have developed a PCR-HRM (High Resolution Melting) analysis targeting three mitochondrial genes—cytochrome oxidase 1 (CO1), cytochrome b (cyt b), and 16S rRNA, to detect 7 species ( goat, sheep, bovines, pig, camel, rabbit and chicken) of commercially traded meat in Kenya. One hundred and seven meat samples (whole pieces) were collected from randomly selected stalls in Nairobi’s major meat wholesale market (Burma market) and butcheries in the 10 surrounding districts.  Out of the 107 samples, 11 (10.3%) had been substituted, with the highest rate being observed in samples sold as goat (7 out of 30 samples). The PCR-HRM assay worked with fresh, dried, heated and decomposed meat, as well as admixtures of the different species. and is regarded as a robust and reliable assay for meat species.
