Abstract
The rise in contamination of raw foods by heavy metals has become an unavoidable problem nowadays.
The episodes of accumulation of heavy metals in the biotic environment result from rapid increase in
industrial activities, advancement in agricultural methods, or the activities of humans in the urban settings.
These activities have prompted metal distribution in the environment and, subsequently, resulting to
impairment in health of the populace by the ingestion of food contaminated by harmful metals components.
The aim of this study was to assess the heavy metals concentrations and characterize the heavy metals
found in raw food samples collected from selected standard hotels in Kaduna State and compare with
the Food Agriculture and Organization (FAO)/World Health Organization (WHO) guidelines so as to
assess the potential health hazard. Twenty samples of rice and nine samples beans were obtained from
20 hotels within three-, four-, and five-star ratings with their purchase sources coded from hotel 1 to 20
for confidentiality. The powdered samples were digested with nitric acid. Extract from the digest was
analyzed for Copper (Cu), Lead (Pb), and Cadmium (Cd) using Buck Scientific AAS. The results of this
research indicated levels of HMs were within safe limit, when compared with FAO/WHO standard and
concentrations are significantly low, as the heavy metals are the same across the samples at P-value set
at 0.05. The results of this study indicated presence of the heavy metals (Copper, Cadmium, and Lead)
in the samples but they were at safe levels when compared with the WHO standard. Despite these, one
should not neglect the fact that the two metals (Cd and Pb) accumulate in the body over time because of
consumption frequency of beans and rice. Bioaccumulation rate can pose serious health risk to consumers.
Implementation of hazard analysis critical control point for routine assessment of heavy metals in food
products to help eliminate of not exceed global standard for food safety should be practice.
Description
Numerous researchers in Nigeria have reported on
adverse effects on human health due to exposure
to some of these heavy metal’s concentration in
drinking water and food, Even though these
heavy metal’s concentrations are toxic to humans,
there exposure cases and the rise in contamination
of raw foods by heavy metals have become an
unavoidable problem nowadays. The
episodes of accumulation of heavy metals in the
biotic environment result from rapid increase in
industrial activities, advancement in agricultural
methods, or the activities of humans in the urban
settings
