Appraisal of hygiene indicators and farming practices in the production of leafy vegetables by organic small-scale farmers in uMbumbulu (Rural KwaZulu-Natal, South Africa).

ABSTRACT: During October, November and December 2011 (when highest sales of Agri-Hub fresh produce are observed), irrigation water, compost, lettuce and spinach sampled from four different farmer cooperatives supplying the local Agri-Hub in uMbumbulu (KwaZulu-Natal, South Africa) were analyzed monthly for the presence of total and fecal coliforms and Escherichia coli using the most probable number (MPN) technique. The pH values for all irrigation water samples analyzed were within the acceptable range of 6.5-8.5 for agricultural use. Fecal coliform levels were <1,000 MPN per 100 mL irrigation water and <1,000 MPN per g of compost. The vegetables produced by Agri-Hub small-scale farmers met the requirements for total coliforms of <200/g set by the South African Department of Health at the time of sampling. E. coli MPN values for irrigation water and vegetables were below the limit of detection. In addition, the farming practices of 73 farmers were assessed via a survey. The results revealed that more than 40% of farmers used microbiologically safe tap water for irrigation and that trained farmers have a significantly better understanding of the importance of production hygiene than untrained farmers. These results reiterate the importance of interventions that build capacity in the area of food safety and hygiene of small-scale farmers for market access of formal value chains.

Project description:BackgroundIn South Africa malaria is endemic in Mpumalanga, Limpopo and the north-eastern areas of KwaZulu-Natal provinces. South Africa has set targets to eliminate malaria by 2018 and research into complementary vector control tools such as the Sterile Insect Technique (SIT) is ongoing. It is important to understand community perceptions regarding malaria transmission and control interventions to enable development of community awareness campaign messages appropriate to the needs of the community. We aimed to assess knowledge, attitudes, and practices regarding malaria transmission to inform a public awareness campaign for SIT in Jozini Local Municipality, Mamfene in KwaZulu-Natal province.MethodsWe conducted a cross-sectional survey in three communities in Mamfene, KwaZulu-Natal during 2015. A structured field piloted questionnaire was administered to 400 randomly selected heads of households. Descriptive statistics were used to summarize data.ResultsOf the 400 participants interviewed, 99% had heard about malaria and correctly associated it with mosquito bites. The sources of malaria information were the local health facility (53%), radio (16%) and community meetings (7%). Approximately 63% of the participants were able to identify three or four symptoms of malaria. The majority (76%) were confident that indoor residual spraying (IRS) kills mosquitoes and prevents infection. Bed nets were used by 2% of the participants. SIT knowledge was poor (9%), however 63% of the participants were supportive of mosquito releases for research purposes. The remaining 37% raised concerns and fears, including fear of the unknown and lack of information on the SIT.ConclusionAppropriate knowledge, positive attitude and acceptable treatment-seeking behaviour for malaria were demonstrated by members of the community. Community involvement will be crucial in achieving success of the SIT and future studies should further investigate concerns raised by the community. The existing communication channels used by the malaria control program can be used; however additional channels should be investigated.

Project description:BackgroundRecent analysis of drinking water in South Africa found the presence of ARVs, other pharmaceutical and personal care products. The environmental and human health risk that this presents is daunting. The increased use of ARVs with poor disposal practices could be the reason for these substances being present in drinking water. Therefore, this study aimed to determine the knowledge and practices of HIV infected patients, regarding medicine disposal.MethodA descriptive, cross sectional, quantitative study that utilised a structured, self-administered, questionnaire was undertaken at 3 different public ARV clinics in the eThekwini Metro of KwaZulu Natal, SA. The variables included questions on demographics, knowledge and practices of medicine disposal of ARV and other medications. Data was captured using excel spreadsheets and analysed using SPSS version 25. Chi square tests were used to compare factors between correct and incorrect knowledge and practice groups.ResultsFour hundred and eighty four participants agreed to participate in this study, of which the majority (71.1%) were females. Over 87% of the participants knew that improper disposal of medicines were harmful to the environment with only 28.3% knowing that there were laws governing the way medicines should be disposed. Majority of participants that had unused and expired ARVs at home disposed of these medicines. The most common route of medicine disposal for ARVs was by throwing these medicines into the bin (56.4%). Only 24.2% of participants were informed by healthcare professionals about the proper method of medicine disposal. Participants who had secondary and tertiary level of education (p = 0.043) and the ability to speak English (p = 0.001) had appropriate knowledge on medicine disposal.ConclusionThis study identified that poor medicine disposal practices and lack of adequate information about the proper methods of medicine disposal were evident among the participant population. There is a need for patient education and healthcare professional intervention to ensure patients are aware of standard proper medicine disposal practices.

Project description:BackgroundThe use of cervical collars in adult patients with possible injuries to the cervical spine has been an accepted standard of care for many years, despite the absence of evidence for the efficacy of these devices in preventing unwanted movement and harm. Changes to the terminology and recommendations of major trauma guidelines have been made but are limited by low quality evidence. In this context, little is known about what practitioners know, believe, and do, when managing the cervical spine of trauma patients.MethodsIn this quantitative, observational, descriptive, cross-sectional survey a specifically designed questionnaire was used to collect data on the knowledge, attitude, and practices of practitioners managing adult trauma patients regarding cervical collars at three hospitals in KwaZulu-Natal, South Africa.ResultsA total of 128 completed questionnaires were collected, captured, and analysed. Participants with the additional qualification of ATLS and DipPEC had a mean knowledge score of 8.1 (SD=1.70), compared to those with no additional qualification of 4.5 (SD=1.9) (p<0.001). Participants in the Emergency Department (ED) attained a mean knowledge score of 7.1 (SD=2.2) followed by Surgery (Mean=6, SD=2.0), Orthopaedics (Mean=5.5, SD=1.7) and ICU/Anaesthetics (Mean=4.4, SD=1.8), p<0.001. Head blocks only were most frequently used by 97.4 % of ED, 55.6 % of Surgery, 3.8 % Orthopaedic and 22.2 % ICU/Anaesthetics participants (p<0.001).ConclusionThe knowledge of management principles of cervical spine injuries was influenced by the department in which practitioners worked, the frequency that they managed patients with suspected injuries and additional courses. Head blocks were the most frequently used spinal protection device in all three hospitals. Most participants would be open to a change in practice if new guidelines were recommended. Further research is needed to determine the optimal management of patients with suspected cervical spine injuries and the role of motion restriction devices in limiting movement of the injured spine.

Project description:ObjectivesResearch on migration and HIV has largely focused on male migration, often failing to measure HIV risks associated with migration for women. We aimed to establish whether associations between migration and HIV infection differ for women and men, and identify possible mechanisms by which women's migration contributes to their high infection risk.DesignData on socio-demographic characteristics, patterns of migration, sexual behavior and HIV infection status were obtained for a population of 11,677 women aged 15-49 and men aged 15-54, resident members of households within a demographic surveillance area participating in HIV surveillance in 2003-04.MethodsLogistic regression was conducted to examine whether sex and migration were independently associated with HIV infection in three additive effects models, using measures of recent migration, household presence and migration frequency. Multiplicative effects models were fitted to explore whether the risk of HIV associated with migration differed for males and females. Further modeling and simulations explored whether composition or behavioral differences accounted for observed associations.ResultsRelative to non-migrant males, non-migrant females had higher odds of being HIV-positive (adjusted odds ratio [aOR] = 1.72; 95% confidence interval [1.49-1.99]), but odds were higher for female migrants (aOR = 2.55 [2.07-3.13]). Female migrants also had higher odds of infection relative to female non-migrants (aOR = 1.48 [1.23-1.77]). The association between number of sexual partners over the lifetime and HIV infection was modified by both sex and migrant status: For male non-migrants, each additional partner was associated with 3% higher odds of HIV infection (aOR = 1.03 [1.02-1.05]); for male migrants the association between number of partners and HIV infection was non-significant. Each additional partner increased odds of HIV infection by 22% for female non-migrants (aOR = 1.22 [1.12-1.32]) and 46% for female migrants (aOR = 1.46 [1.25-1.69]).ConclusionsHigher risk sexual behavior in the context of migration increased women's likelihood of HIV infection.
