“…In food industry however, the slime makes the meat less attractive during processing. According to Etengeneng et al (2021), the flesh of snails contained some amount of slime and, when removed using the right method, rendered it more attractive and appetizing. Separating the meat from its shell during processing is also time-consuming and provided an opportunity for cross-contamination of the flesh during dressing.…”

African giant snail is a popular alternative source of animal protein in Ghana and many other countries. The meat is high in lean protein and mineral elements. Ready-to-use meat obtained from snails can compete with animal proteins found on the market. After shelling, snails produced some slime that interfered with preparation and processing of the meat. This study aimed to provide consumers with ready-to-use fresh snails conveniently available on the market. The best treatment for eliminating slime from snails was determined using a 2×10×3 factorial design. Vinegar plus salt treatment was the most effective slime removal treatment which led to a significant weight loss. Irradiation at all doses most effectively reduced the microbial load of snails after slime removal. A 6×4×3 factorial design was used for the shelf-life study. Irradiation at 1.5 and 3 kGy extended the shelf life of fresh snails by 14 extra days with the lowest microbial load. Radiation did not affect the fat and mineral content, but the protein content increased. Panelists preferred irradiated snails even though they had different odours and aromas. This study concluded that irradiating fresh snails even at lower doses can extend the shelf-life of fresh snails under refrigeration temperature.

The escalation of environmental pathogenic microorganisms and disregard of public hygiene practices have resulted in the emergence of various skin infections within communities. Recent investigations have proposed that diverse snail mucus compositions may possess antimicrobial properties. Therefore, it is imperative to conduct further research to elucidate specific antibacterial characteristics inherent in the mucus of White Garden snail (Theba pisana). This study aimed to evaluate antibacterial activity of Theba pisana mucus extract against selected ATCC bacterial strains being Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, and MRSA. The assessment involved comparing antimicrobial activity of the mucus extract to various broad-spectrum antibiotics. The susceptibility of bacterial isolates to snail mucus secretions was assessed using agar well diffusion method on Muller Hilton Agar plates. After incubation at 37°C for 24 hours, various concentrations of snail slime including 100%, 75%, 50%, and 25% were applied. The findings reported that E. faecalis exhibited highest activity, with zone of inhibition measuring 24 mm, followed by K. pneumonia and S. aureus (16 mm), MRSA (14 mm), and E. coli (12 mm). However, at concentration of 25%, mucus extract exhibited effect only against E. faecalis. Moreover, the antimicrobial activity of several tested antibiotics demonstrated similarity to that of the mucus extract. Therefore, it revealed that secretions of T. pisana mucus may possess the potential to act as a source of antibacterial agents. This may become as an alternative agent to costly synthetic antibacterial compounds. However, further studies are required to exploit the mucus secretion in addressing the issue of antibiotic resistance.
