Risk of faecal pollution among waste handlers in a resource-deprived coastal peri-urban settlement in Southern Ghana.

ABSTRACT: Resource-deprived coastal peri-urban settlements in Southern Ghana are characterized by indiscriminate solid waste disposal and open defecation practices. Persons engaged in waste handling in such communities perform their activities with little or no personal protective equipment. They are thus confronted with the risk of faecal pollution of the hands and other bodily parts. A mixed method approach was used to investigate 280 waste handlers performing different activities to estimate recent faecal pollution of their hands and to observe the utilization of personal protective equipment and sanitation/hygiene facilities during work. The log concentration of E. coli on hands of waste handlers after work (8.60 ± 4.20 CFU/hand, mean ± standard deviation) was significantly higher compared with the E. coli log concentration before work (2.95 ± 1.89 CFU/hand, mean ± standard deviation) (p<0.001). The odds of faecal pollution was significantly higher (aOR 4.2; 95% CI: 1.9-9.1) for workers aged 35 years and above compared with those less than 35 years; and for workers at public toilet facilities (aOR 3.0; 95% CI: 1.0-8.4) compared with those who worked for private waste handling companies. Female workers were, however, 60% less likely (aOR 0.4; 95% CI: 0.2-0.8) to experience faecal pollution of their hands compared with males. The workers had limited access to water and sanitation and hygiene facilities, and about one-fifth (n = 59; 21.1%) did not use personal protective equipment during work. Waste handlers should be provided and instructed in proper use of personal protective equipment, have access to sanitation facilities and adopt improved hygiene behaviour to avoid the risk of faecal pollution and associated disease risk.

Project description:BACKGROUND:Cutaneous leishmaniasis is a neglected disease known to cause significant morbidity among the poor. We investigated a suspected outbreak to determine the magnitude of cases, characterize the cases and identify risk factors of cutaneous leishmaniasis in Gilgil, a peri-urban settlement in Central Kenya. METHODS:Hospital records for the period 2010-2016 were reviewed and additional cases were identified through active case search. Clinical diagnosis of cutaneous leishmaniasis was made based on presence of ulcerative, nodular or papular skin lesion. The study enrolled 58 cases matched by age and neighbourhood to 116 controls in a case control study. Data was collected using structured questionnaires and simple proportions, means and medians were computed, and logistic regression models were constructed for analysis of individual, indoor and outdoor risk factors. RESULTS:Of the 255 suspected cases of cutaneous leishmaniasis identified, females constituted 56% (142/255) and the median age was 7 years (IQR 7-21). Cases occurred in clusters and up to 43% of cases originated from Gitare (73/255) and Kambi-Turkana (36/255) villages. A continuous transmission pattern was depicted throughout the period under review. Individual risk factors included staying outside the residence in the evening after sunset (OR 4.1, CI 1.2-16.2) and visiting forests (OR 4.56, CI 2.04-10.22). Sharing residence with a case (OR 14.4, CI 3.8-79.3), residing in a thatched house (OR 7.9, CI 1.9-45.7) and cracked walls (OR 2.3, CI 1.0-4.9) were identified among indoor factors while sighting rock hyraxes near residence (OR 5.3, CI 2.2-12.7), residing near a forest (OR 7.8, CI 2.8-26.4) and having a close neighbour with cutaneous leishmaniasis (OR 6.8, CI 2.8-16.0) were identified among outdoor factors. CONCLUSIONS:We identify a large burden of cutaneous leishmaniasis in Gilgil with evidence of individual, indoor and outdoor factors of disease spread. The role of environmental factors and rodents in disease transmission should be investigated further.

Project description:BackgroundFood safety and hygiene are currently a global health apprehension especially in unindustrialized countries as a result of increasing food-borne diseases (FBDs) and accompanying deaths. This study aimed at assessing knowledge, attitude, and hygiene practices (KAP) of food safety among street-cooked food handlers (SCFHs) in North Dayi District, Ghana.MethodsThis was a descriptive cross-sectional study conducted on 407 SCFHs in North Dayi District, Ghana. The World Health Organization's Five Keys to Safer Food for food handlers and a pretested structured questionnaire were adapted for data collection among stationary SCFHs along principal streets. Significant parameters such as educational status, average monthly income, registered SCFHs, and food safety training course were used in bivariate and multivariate logistic regression models to calculate the power of the relationships observed.ResultsThe majority 84.3% of SCFHs were female and 56.0% had not attended a food safety training course. This study showed that 67.3%, 58.2%, and 62.9% of SCFHs had good levels of KAP of food safety, respectively. About 87.2% showed a good attitude of separating uncooked and prepared meal before storage. Good knowledge of food safety was 2 times higher among registered SCFHs compared to unregistered [cOR=1.64, p=0.032]. SCFHs with secondary education were 4 times good at hygiene practices of food safety likened to no education [aOR=4.06, p=0.003]. Above GHc1500 average monthly income earners were 5 times good at hygiene practices of food safety compared to below GHc500 [aOR=4.89, p=0.006]. Registered SCFHs were 8 times good at hygiene practice of food safety compared to unregistered [aOR=7.50, p<0.001]. The odd for good hygiene practice of food safety was 6 times found among SCFHs who had training on food safety courses likened to those who had not [aOR=5.97, p<0.001].ConclusionsOver half of the SCFHs had good levels of KAP of food safety. Registering as SCFH was significantly associated with good knowledge and hygiene practices of food safety. Therefore, our results may present an imperative foundation for design to increase food safety and hygiene practice in the district, region, and beyond.
