A Comprehensive Review of Reptile Meat as an Alternative Protein Source: Nutritional Composition, Safety Concerns, Environmental Impact and Welfare Issues
Keywords:
environment, food safety, nutritional composition, reptile farming, reptile meat, welfare.Abstract
This review investigates the feasibility of reptile meat as an alternative protein source in the context of rising global protein demand and the need for sustainable food systems. It synthesizes current knowledge on edible reptile species (crocodiles, turtles, snakes and lizards), their farming and geographic distribution and the key nutritional, safety, environmental and welfare aspects associated with their use for human consumption. Available data indicates that reptile meat, particularly from crocodiles, snakes and some turtles, is characterized by high protein content, favourable fatty acid profiles (including essential n‑3 and n‑6 polyunsaturated fatty acids) and appreciable levels of essential amino acids and minerals, making it nutritionally comparable or superior to conventional livestock meats. However, important concerns persist regarding microbiological and chemical hazards, parasites, traceability and the role of reptile farming and harvesting in overexploitation, biodiversity loss and animal welfare challenges. This review highlights substantial regional differences in cultural acceptance and regulatory oversight and identifies major gaps in nutritional composition data, risk assessments, legislation and welfare guidelines for reptile farming and reptile meat safety and quality. Overall, reptile meat may contribute to protein diversification, but its broader commercialization should be contingent on robust food safety management, conservation-compatible sourcing and species-specific welfare standards.
