Characterization of meat retail conditions in Kigali city (Rwanda): hygienic practices and determinants for Salmonella occurrence

Salmonella is one of the leading bacterial food borne pathogens worldwide and meat constitutes one of the major vehicles for human Salmonella infections. Salmonella illnesses represent an important public health concern particularly in countries with growing economies such as Rwanda. The objective of this study was to characterize the retail conditions and to determine the microbiological quality and safety of meat retailed within the establishments of Kigali city. A survey was carried out in 150 establishments of Kigali city to characterize the meat retail conditions through a structured questionnaire, whereas 270 meat samples were analyzed for the enumeration of hygiene indicator bacteria and the qualitative detection of Salmonella by using conventional culture methods. Furthermore, the risk factors associated to the occurrence of Salmonella in the commercialized meat pieces were identified trough a binary logistic regression analysis. The first results from this study indicate that beef is the type of meat sold the most within retail premises of Kigali city and meat from animal species other than bovines are generally commercialized in large establishments. The levels of hygiene indicator bacteria were found to be relatively high and Salmonella was detected in 19.6% of all retailed meat samples. Factors such as the exposition of retailed meat at ambient temperature, the utilization of wooden cutting boards with rough surfaces which are difficult to sanitize as well as the lack of trained personnel in hygienic meat handling practices; were found to be significantly associated to the risk of Salmonella occurrence in the retailed meat. The findings from this study highlight the need for improvements in hygienic meat handling practices particularly in small and medium meat retail establishments in Kigali cit

Estimates of disease burden caused by foodborne pathogens in contaminated dairy products in Rwanda

Abstract Background The Girinka program in Rwanda has contributed to an increase in milk production, as well as to reduced malnutrition and increased incomes. But dairy products can be hazardous to health, potentially transmitting diseases such as bovine brucellosis, tuberculosis, and cause diarrhea. We analyzed the burden of foodborne disease due to consumption of raw milk and other dairy products in Rwanda to support the development of policy options for the improvement of the quality and safety of milk. Methods Disease burden data for five pathogens (Campylobacter spp., nontyphoidal Salmonella enterica, Cryptosporidium spp., Brucella spp., and Mycobacterium bovis) were extracted from the 2010 WHO Foodborne Disease Burden Epidemiology Reference Group (FERG) database and merged with data of the proportion of foodborne disease attributable to consuming dairy products from FERG and a separately published Structured Expert Elicitation study to generate estimates of the uncertainty distributions of the disease burden by Monte Carlo simulation. Results According to WHO, the foodborne disease burden (all foods) of these five pathogens in Rwanda in 2010 was like or lower than in the Africa E subregion as defined by FERG. There were 57,500 illnesses occurring in Rwanda owing to consumption of dairy products, 55 deaths and 3,870 Disability Adjusted Life Years (DALYs) causing a cost-of-illness of $3.2 million. 44% of the burden (in DALYs) was attributed to drinking raw milk and sizeable proportions were also attributed to traditionally (16–23%) or industrially (6–22%) fermented milk. More recent data are not available, but the burden (in DALYs) of tuberculosis and diarrheal disease by all causes in Rwanda has declined between 2010 and 2019 by 33% and 46%, respectively. Conclusion This is the first study examining the WHO estimates of the burden of foodborne disease on a national level in Rwanda. Transitioning from consuming raw to processed milk (fermented, heat treated or otherwise) may prevent a considerable disease burden and cost-of-illness, but the full benefits will only be achieved if there is a simultaneous improvement of pathogen inactivation during processing, and prevention of recontamination of processed products

Impact of Breast Cancer Early Detection Training on Rwandan Health Workers’ Knowledge and Skills

Purpose: In April 2015, we initiated a training program to facilitate earlier diagnosis of breast cancer among women with breast symptoms in rural Rwanda. The goal of this study was to assess the impact of the training intervention in breast cancer detection on knowledge and skills among health center nurses and community health workers (CHWs). Methods: We assessed nurses’ and CHWs’ knowledge about breast cancer risk factors, signs and symptoms, and treatability through a written test administered immediately before, immediately after, and 3 months after trainings. We assessed nurses’ skills in clinical breast examination immediately before and after trainings and then during ongoing mentorship by a nurse midwife. We also examined the appropriateness of referrals made to the hospital by health center nurses. Results: Nurses’ and CHWs’ written test scores improved substantially after the trainings (overall percentage correct increased from 73.9% to 91.3% among nurses and from 75.0% to 93.8% among CHWs (P < .001 for both), and this improvement was sustained 3 months after the trainings. On checklists that assessed skills, nurses’ median percentage of actions performed correctly was 24% before the training. Nurses’ skills improved significantly after the training and were maintained during the mentorship period (the median score was 88% after training and during mentorship; P < .001). In total, 96.1% of patients seen for breast concerns at the project’s hospital-based clinic were deemed to have been appropriately referred. Conclusion: Nurses and CHWs demonstrated substantially improved knowledge about breast cancer and skills in evaluating and managing breast concerns after brief trainings. With adequate training, mentorship, and established care delivery and referral systems, primary health care providers in sub-Saharan Africa can play a critical role in earlier detection of breast cancer

Characteristics and early outcomes of cervical cancer patients at Butaro District Hospital, Rwanda: a retrospective review

Background: Cancer treatment facilities are scarce in rural areas of low-income and middle-income countries, where the highest burden of cervical cancer exists. The Butaro Cancer Center of Excellence (BCCOE), in rural Rwanda, is a Rwandan Ministry of Health facility supported by Partners In Health and Dana-Farber/Brigham and Women's Cancer Center. The cervical cancer programme includes diagnosis, staging, and treatment. However, because of resource limitations, only 15 patients per month could be referred for radiotherapy to the Uganda Cancer Institute. In this study, we describe cervical cancer treatment at BCCOE and early patient outcomes. Methods: In July, 2016, we retrospectively reviewed records for patients with cervical cancer enrolled between July 1, 2012, and June 30, 2015, at BCCOE. We extracted data on patients' characteristics, disease stage, treatment, and outcomes. Findings: We included 438 patients: median age was 52 years (IQR 42–60 years), 35 patients (8%) had laboratory-confirmed HIV, 142 (36%) smoked tobacco, median number of pregnancies was 7 (IQR 5–9), and 41 (10%) had had a hysterectomy before enrolment. 258 patients (60%) had a diagnosis confirmed by pathology, and 391 patients (91%) had a documented disease stage. Of these, 13 (3%) were Stage I, 183 (47%) were Stage II, 154 (39%) were Stage-III, and 41 (11%) were Stage IV. There was a curative, instead of palliative or undecided, intent for 85% of Stage I patients, 91% of Stage II, and, 12% of Stage III. 165 women (38%) were referred for concurrent radiation therapy, chemotherapy, and brachytherapy in Uganda, and 19 (4%) were referred for radical hysterectomy. At their last recorded visit, 77 patients (18%) had no evidence of recurrence, including: 6 (46%) Stage I patients, 66 (37%) Stage II, 5 (3%) Stage III, but no Stage IV patients (p =<0·0001). Overall, 114 patients (27%) were lost to follow-up during or after treatment. Interpretation: Our experience shows that a cervical cancer treatment programme is viable in a low-resource, rural setting. However, many challenges exist, especially the severity of disease at intake (about half of patients presented with Stage III or IV disease) and that there are no radiation facilities in Rwanda. Further, a quarter of patients were eventually lost to follow-up during the study. Future implementation interventions will focus on strategies to overcome these challenges.
