Purpose

The primary objective was to determine the prevalence of indicator microorganisms [Staphylococcus aureus, non-S. aureus staphylococci (NSAS), coliforms and aerobic bacteria] for contamination of chicken carcasses, carcass drip and rinse water from the informal chicken market in Gauteng, South Africa.

Design/methodology/approach

Chicken swabs, chicken drips and rinse waters were collected from 151 chickens from 47 random outlets. Pre-tested questionnaires were administered to capture the risk factors for bacterial contamination. Standard microbiological procedures were conducted for isolation and enumeration of target bacteria.

Findings

NSAS (64% and 41%) and S. aureus (12% and 31%) were prevalent on carcasses and in carcass drip respectively. Coliforms (62%) and aerobic bacteria (85%) were detected in rinse water. Significant risk factors for contamination of carcasses with NSAS, S. aureus and coliform organisms were: evisceration of chickens on the same location used for sale, cleaning of display counter with dirty clothes/wipes, holding of differently sourced chickens in the same cage prior to slaughter, not cleaning the display table/counter and hands at all, washing knives in rinse water, high turnover of daily slaughter and length of time to display chickens.

Research limitations/implications

The limitations of this research were the limited geographical coverage and small sample size.

Practical implications

The isolation of these indicator microorganisms suggests the potential presence of other chicken-borne pathogens not tested for in the study.

Social implications

The findings serve to inform policy on public health and street-vended food and can guide control on good sanitary practices.

Originality/value

This is the first comprehensive report on ready to eat chickens from the informal markets in Gauteng, South Africa.

在南非豪登省的非正式市场上宰杀的鸡，其葡萄球菌和大肠菌的contamination体污染的发生率和风险

目的

主要目的是确定用于感染鸡car体，car体滴水和冲洗水的细菌的指示微生物[金黄色葡萄球菌，非金黄色葡萄球菌葡萄球菌（NSAS），大肠菌和需氧细菌]的流行非洲。

设计/方法/方法

从47个随机出口点的151只鸡中收集了鸡拭子，鸡滴水和冲洗水。进行预先测试的问卷以捕获细菌污染的风险因素。进行标准微生物程序以分离和计数目标细菌。

发现

NSAS（64％和41％）和金黄色葡萄球菌（12％和31％）分别在car体和drip体滴液中盛行。在冲洗水中检出大肠菌（62％）和有氧细菌（85％）。N体被NSAS，金黄色葡萄球菌和大肠菌污染的重要危险因素是：将鸡出售处在同一地点，将鸡鸡内脏，用脏衣服/湿巾清洁展示柜，将不同来源的鸡存放在同一笼子中，然后再出售。屠宰，根本不清洁展示台/柜台和手，用冲洗水洗刀，每天的屠宰周转率高，展示鸡的时间长。

研究局限/意义

该研究的局限性是有限的地理覆盖范围和较小的样本量。

实际影响

这些指示微生物的分离表明，该研究中未测试的其他鸡源性病原体也可能存在。

社会影响

这些发现有助于为公共卫生和街头食品提供政策依据，并可以指导对良好卫生习惯的控制。

创意/价值

这是有关南非豪登省非正式市场上即食鸡肉的第一份综合报告。
