BIOCHEMICAL EVALUATION OF MEAT AND HAEMOLYMPH OF AFRICAN LAND SNAIL (Archachatina marginata, Swainson) IN SOUTH-WEST NIGERIA

“…The highest iron concentration in this experiment was obtained in snail haemolymph, and this agreed with the findings of [7,16] that iron is more abundant in the haemolymph. Iron is an integral part of the blood which attracts oxygen for cellular oxidation of anaemia, and the availability of other essential minerals like calcium, magnesium and zinc in snails may justify the drinking of snails' haemolymph by pregnant women and for traditional treatment of hypertension [5,14,18].…”

This study investigated the morphological characteristics, and chemical composition of Archachatina marginata (African Giant Land Snail) reared on Quail droppings meal (QDM.) substituted for protein sources in snail feed. Five trial snail feeds (Diet I-V) were fed to fifty snails (average weight 157.3 g) for 12 weeks. The morphological characteristics of the snail and its flesh and haemolymph chemical composition were determined using standard methods. There was an appreciable increase in the growth parameters (weight, shell width and shell length) across the treatment groups. The feed conversion ratio (FCR) ranges from 2.74 to 3.75, and snails served Diet I gave the highest FCR. The result of the proximate analysis revealed that snail flesh possessed a higher amount of protein, fat, ash, fibre and energy except carbohydrate than hemolymph. Increasing QDM in the diets increased the proximate contents of the snail's flesh and hemolymph, except fat and fibre. The minerals found in all the treatments are not toxic, and snails fed diet V possessed the highest mineral contents (sodium, potassium, calcium, magnesium, iron and phosphorus). The result showed that diet V resulted in the best morphological parameters and feed utilisation of A. marginata snail. Substituting protein sources with QDM in snail feed improved the nutritional quality of snails, reducing the cost of the compounded ration.

“…Heavy metal bioaccumulation is triggered through the food chain due to the absorption of these metals from water, sewage, agrochemicals, industrial wastes and wastes from mining centres (Alam et al, 2003, Agbon and. It is very common in the Southern parts of Nigeria to found gatherers collecting snails, immediately after rain (Kehinde et al, 2020). These animals feed on forages, organic matters and soil, which have all been implicated in the storage of heavy metals in order to determine the safety of snail meat consumption in the areas where they are found, all the common breeds (Archachatina marginata, Achatina achatina, Achatina falica and Limicolaria species) must be screened to determine if they are fit for human consumption.…”

The impact of captive rearing of snails (Archachatina marginata) on the bio-accumulation of some heavy metals (HMs) (Fe, Mn, Cu, Pb, Co, Ni, Cd and Cr) in the meat and haemolymph was evaluated in a two treatment trial (snails from the wild, (SW) and captive reared snails, (SC), each comprised of sixty snails of three replicates. Alldata collected (using standard analytical procedures) were subjected to ANOVA and significant means separated by Duncan Multiple Range Test. The trial revealed that the meat of SC had outstanding (P>0.05) Fe (22.30mg/kg) and Mn(4.79mg/kg), with no significant variation for DM, while the haemolymph recorded non-significant (P< 0.05) concentration for (Mn, Pb, Co, Ni, Cd and Cr). Its levels of Fe (3.50mg/kg) and Cu (2.06mg/kg) were however significantly (P>0.05) impacted by captive rearing. Generally the level of Cr in the meat and haemolymph were higher than 0.05mg/kg recommendation by WHO, hence snail meat and haemolymph must be consumed with caution and guidance.
