Abstract

Context

An adequate infrastructure facility is a prerequisite for achieving clean and hygienic meat production from sheep and goats. In India, most of the meat is produced by small-scale producers who cannot afford to establish large-scale abattoirs.

Aim

The study aimed to develop and test an innovative Portable Meat Production and Retailing Facility (P-MART), designed to meet the specific requirements of small-scale sheep and goat slaughter operations processing less than 10 animals per day.

Methods

The designing and fabrication of P-MART comprises of animal resting facility, slaughtering and dressing facility, meat cutting and packaging facility, meat retailing facility, and waste management facility. The microbiological evaluation was conducted by collecting meat samples/swabs (n = 6) from various stages of the slaughter of sheep and goats in P-MART. The quality of the liquid effluent from the slaughter process (n = 6) of P-MART was evaluated for different parameters. The gastrointestinal waste was subjected to aerobic composting and compost samples (n = 6) were analyzed for different parameters. The P-MART liquid waste was subjected to anaerobic biomethanation (n = 6) and the quality of the liquid fertilizer was assessed for different parameters. The air quality index in P-MART was analyzed in alignment with Environmental Protection Training and Research Institute (EPTRI) standards compliance with National Ambient Air Quality Standards (NAAQS).

Key results

The P-MART demonstrated effectiveness in addressing small-scale slaughterhouse needs. Microbiological analysis confirmed the absence of harmful organisms such as E. coli, Salmonella, and Listeria in meat, surfaces and water, showcasing high hygiene standards. The aerobic composting of gastrointestinal waste resulted in composting with nutrient concentrations that met recommended standards and the biomethanation of liquid waste produced nutrient-rich liquid fertilizer and biogas for cooking. Air quality parameters, including particulate matter with 10 μm or less, or 2.5 μm or less, sulfur dioxide and nitrogen dioxide, were within permissible limits, ensuring a safe environment.

Conclusions

P-MART design minimizes water use and supports humane slaughter, sustainable waste management and environmental compliance. An application for an Indian patent was submitted (Patent application No. 202111016135) to protect intellectual property. The technology was commercialized to enable upscaling and marketing.

Implications

The P-MART can improve livelihoods for small-scale meat producers by offering affordable and hygienic slaughter facilities. Its sustainable waste management practices enhance public health and environmental protection.
