In addition, an inframarginal economic analysis framework has been built for the management and protection compensation problems faced by non-commercial forests under different ownership in the perspective of the division of labor. Research results show that: the compensation standard for the management and protection expenses of non-commercial forests shall fall in between the "completely self-sufficient forestry economic structure U(Ayz)" and the "completely specialized productive structure of non-commercial forests U(B1)".展开更多

However, shelf life, spoilage and hygiene levels have been postulated to vary based on the type of processing system. Live-open non-commercial processing systems are popular among majority consumers owing to their perceived “freshness”, compared to commercially dressed chickens. In between, consumers have to balance freshness and quality assurance. Ultimately, this becomes inert, remotely but an important public health issue. However, lack of empirical evidence on safety levels to guide consumer product selection leaves them to speculation. It is this need to close this gap that created an impetus for us to undertake this study. <strong>Methods:</strong> Biological samples were collected before carcass wash and after carcass wash alongside a structured questionnaire that gathered risk-associated data. Standard microbiological enumeration methods were used to isolate bacteria and enumerate contamination. <strong>Results:</strong> Broiler carcasses processed from “open” non-commercial systems were more contaminated (45.6%) than “closed-abattoir” commercially processed systems (35%). <em>Escherichia coli</em> were major contaminants (71.3%) and few <em>Salmonella</em> spices (typhi or para-typhi) in 1.3%. Risk analysis indicates washing (method) of carcasses at commercial systems was significantly more risky for contamination than non-commercial ones. Major sources of contamination were “distance from water sources”. Increased volume of slaughters per day (>15,000 birds) for commercial systems accounted for increased cross-contamination, particularly, distance from water source was a ma-jor risk factor for contamination.展开更多
