Evaluation of African giant snails (Achatina and Archachatina) obtained from markets (wild) and breeding farms

Abstract

In the Greater Accra Region there is high demand in consumption of molluscs, which indicates the need for studies on the possibility of disease transmission. Snail meat is usually susceptible to microbial contamination. Shelling is difficult with possibilities of cross contamination. Slime on the meat becomes a hurdle during commercial processing. The objective of the study was to establish the differences in the microbial load of African land snails (Achatina achatina and Archachatina marginata) from two sources (market and breeding farm) and to enumerate some consumer concerns about the snail meat. The results found that the total viable count (log 10 CFU/g) ranged from 6.61±1.25 to 8.29±1.02. The total of coliform count (log 10 CFU/g) ranged from 8.50±0.57 to 5.61±1.51. Salmonella count (log 10 CFU/g) ranged from 2.91±3.19 to 7.39±0.45. Staphylococcus, Bacillus and Pseudomonas counts (log 10 CFU/g) ranged from 7.68±1.40 to 2.66±2.99; 4.90±1.07 to 1.53±1.68 and 5.66±0.14 to 3.97±0.74, respectively. Most microorganisms identified were from the Enterobateriaceae family. Shelling, slime removal, contamination, price, packaging were problems associated with snail meat.
