Street Pork Vendors' Hygiene and Safety Practices and Their Determinants in the Cape Metropole District, South Africa.

South Africa's rapid urbanization and high unemployment rates pushed people into street food vending as an alternative source of livelihood. Hygiene and food safety have become a concern under these circumstances owing to foodborne illnesses and associated deaths. A survey tool with 38 structured questions was administered to 172 to assess pork vendors' hygiene and safety practices and identify their determinants in five low-income high-density suburbs of the Cape Metropole District, South Africa. Overall, vendors washed their hands before and after handling meat (66% of respondents) and cleaned the working area daily (51%), pork storage area daily (60%), and utensils and equipment before and after use (36%) with most of them using detergents as the main cleaning agent (70%). A quarter of the interviewed vendors experienced meat spoilage during storage, and 80% had no training in hygiene and safe food handling. The marginal effects of logistic regression findings showed that vending income increased the vendor's probability to wash hands, and clean vending stalls, storage areas, utensils, and equipment. The likelihood of vendors cleaning pork storage areas, utensils, and equipment increased with the increase in female participants. The likelihood of hand washing and vending stall cleaning increased by 1% for each extra year of schooling. Strategies aimed at improving meat hygiene and safety practices of vendors in the surveyed areas should target vulnerable groups, especially less educated females depending solely on vending income.

Quality and safety of pork sold in the informal urban street markets of the Cape Metropole, South Africa.

Pork in the informal market significantly contributes to food, nutrition and income security in low-income countries' urban areas but is a safety concern to value chain actors and public authorities due to potential contamination by pathogens. To evaluate the physicochemical quality, microbial and oxidative profiles of pork sold from the informal urban street market, 50 samples were collected from 40 street vendors and 10 supermarkets in five different low-income, high-density suburbs in the Cape Metropole District, South Africa. Results showed no differences (P > 0.05) in pH, colour, proximate attributes (except for lipid content), antioxidant activity, lipid oxidation, and Escherichia coli counts in pork collected from the formal and informal markets, and open-air and enclosed market stalls. Lipid content, Enterobacteriaceae, and total bacterial counts of pork collected from the informal market were higher (P ≤ 0.05) than those from the formal market. Positive cases of Listeria monocytogenes (6-8%) and Salmonella spp. (4%) were reported for pork sampled in the informal market, especially in open-air stalls. It was concluded that higher levels of microbial contamination in the informal market, particularly in open-air stalls compared to the formal market require constant monitoring, provision of appropriate market infrastructure, and hygiene behaviour change of vendors to ensure pork safety.
