Determination of bacterial population and the presence of pesticide residues from some Cameroonian smoked and dried fish

The objective of this study was to identify the dominant bacterial flora linked hygiene dried and smoked fish in different geographical locations determine presence pesticide residues on processed fish. Fish species were listed collected. ecology from northern zone Cameroon probed using a molecular technique employing variable regions 16S rDNA profiles generated by PCR-DGGE (Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis). obtained sequencing bands Chromatography coupled with mass spectrometry (GC-MS / MS), tested 11 samples. Fifty three percent smoked. Three types pesticides have been identified Among them, there Cypermethrin (15 3600 µg/kg), Chlorpyrifos (19 8800 µg/kg) Profenophos (62 92 µg/kg). analysis profile DNA revealed 32 grouped into 22 genera. Dried most contaminated. Species such as Vagococcus carniphilus, Kurthia gibsonii, Lysinibacillus endophyticus, Macrococcus caseolyticus Bacillus atrophaeus present samples all locations. On general note, are poor microbiological sanitary quality.
