HEALTH RISK ASSESSMENT OF SOME FREQUENTLY CONSUMED YOGHURT IN MALUMFASHI LOCAL GOVERNMENT AREA, KATSINA STATE

For a lot of people, diet is the main route of exposure to trace metals, so the assessment risk of these elements to human via diary intake is important. The non-carcinogenic health risk of Pb, Cd, Cr and Cu to men, women and children via some frequently consumed Yoghurt marketed in Malumfashi local government area of Katsina state was estimated. The mean concentrations of the heavy metals obtain in the Yoghurt samples were below the WHO and FAO permissible limits with the exception of Cd in Hamdala Yoghurt which shows concentration higher than the WHO/FAO permissible limits (0.012±0.11 against 0.05).  The target hazard quotients (THQs) and hazard index (HI) were calculated to evaluate the non-carcinogenic health risk from individual heavy metal and combined heavy metals due to Yoghurt intake. THQs for individual heavy metal from consuming individual analyzed Yoghurt in Malumfashi were all less than one, indicating that health risk associated with the intake of a single heavy metal through consumption of only one kind of Yoghurt was relatively absent. Also health risk from consuming all the analyzed Yoghurt i.e. combined heavy metals (HIs) was also found to be less than one, indicating that the health risk associated with the intake of combined heavy metals from all the analyzed samples was also relatively absent.  the analyzed samples was also relatively absent.
