Abstract

Attaining shrimp safety and quality management in developing countries entails the assessment of parameters that determines their level for consumption. Hence, the heavy metal concentration in white shrimp (Nematopalaemon hastatus) collected along the supply in the continental shelf of Nigeria and their associated health and ecological risk were evaluated using standard methods. Results indicated that Zinc was the highest (19.38mgkg^-1, 56.57mgkg^-1 and 56.64mgkg^-1) heavy metal in the samples collected at landing, processing and marketing segments of the supply chain respectively. The study further indicated that the health quotient and ecological risk index for all the heavy metals evaluated in the N. hastatus had values that were less than one (1). This implies that the entire population would not experience the hazard of heavy metal (Cd, Cu, Fe, Pb, Ni, Mn, and Zn) in later life due to the consumption of N. hastatus. It equally indicated that the shrimp posed no ecological risk in the Nigerian continental shelf. Hence, the entire human population who consumes/utilize N. hastatus can continually depend on the supply of safe N. hastatus from the Nigerian continental shelf. The study recommends increased utilization of white shrimp in value-added food products to sustain/attain healthy living and promotion of well-being in Nigeria and in other developing nations.
