Proximate composition and bioaccumulation of heavy metals in edible Achatina spp in some rural agro-settlements, south-east Nigeria

Abstract Background Animals that live and feed on the soil and its constituents and products naturally absorb heavy metals and pass to other organisms linked in the food chains. The present study was designed to examine bioaccumulation of heavy metals levels and proximate composition quality in edib...

The present study was designed to examine bioaccumulation of heavy metals levels and proximate composition quality in edible Achatina spp sampled in agro-rural settlements, south-east Nigeria. Results The proximate composition recorded the presence of moisture, protein, crude fibre, fat and oil, ash, carbohydrates, nitrogen and calcium, which were similar across selected Achatina spp except for calcium, which was significantly higher in A. achatina. The bioaccumulation factors of heavy metal contents in snails were generally low (below recommended tolerable limits according to WHO standard). Conclusion The good number of nutrients recorded in proximate composition makes the Achatina spp an alternative to domestically farmed animals. Achatina achatina contained most calcium level compared with Achatina fulica and Achatina marginate. The bioaccumulation factors of heavy metal contents in snails were generally low (below recommended tolerable limits according to WHO standard).
