Vol. 8 No. (1): 30 - 37 (2017): BACTERIOLOGICAL SAFETY ASSESSMENT OF MILK AND MILK PRODUCTS SOLD IN SOME PARTS OF KADUNA STATE, NIGERIA

A total of 320 fresh milk and milk products comprising of 80 samples each of fresh milk,
“nono”, “kindrimo” and “manshanu” respectively were collected from four Local
Government Areas of Kaduna state. The samples were subjected to microbiological
techniques for the isolation of pathogenic bacteria. The isolated organisms were identified
by standard bacteriological methods. The organisms identified were; Bacillus spp. 11.25%,
Staphylococcus aureus 8.75%, Staphylococcus spp. 8.75%, Proteus spp. 6.88%,
Providencia spp. 2.50%, Pantoea agglomerans 1.25%, Escherichia coli 0.94%,
Acinetobacter lwoffi 0.94%, Hafnia alvei 0.63%, Salmonella pullorum 0.31%, Acetobacter
haemolyticus 0.31% and Citrobacter diversus 0.31%. The study showed that these milk
and milk products could be an important source of infection with a wide range of
organisms particularly Enterobacteria. There is therefore the need to institute effective
control measures and improved hygiene handling of milk and milk products to protect
public health.
