Author: Awadelkareem, Wefag Awadelkareem Boshra
Abstract: Background: Giardia intestinalis is the commonest gastrointestinal protozoal pathogen worldwide, and causes acute and chronic diarrhoea with malabsorption. Food handlers are directly involved in preparation and distribution of food in societies, and play a major role in ensuring food safety throughout the chain of producing, processing, storage and preparation. The spread of diseases by food handlers is a common problem worldwide. Approximately 280 million people worldwide suffer from giardiasis every year. The prevalence of giardiasis range between 2% to 5% in developed countries and between 10% to 50% in developing countries. This descriptive market based study was conducted at Elhassahisa Town- Gezira State-Sudan, with an objective to study the epidemiology of giardiasis among food handlers in restaurants. Methods: The study covered all workers in restaurants (n=208). Data were collected using structured and pre-prepared questionnaire, observation, interview, and laboratory diagnosis .Data were analyzed using SPSS version 20, and the associations between different variables were checked using X2 test at 95% confidence level. Results: The study showed the rate of infection with giardiasis among food handlers was (20.7%), and that the majority of the infection (90.7%) was in cyst form. The majority of food handlers (96.6%) washed their hands before eating, the same percentage (96.6%) washed their hands before preparing foods, (82.2%) washed their hands after using latrine and some of them (54.4%) used waterVII only to wash their hands. From the observation, the main source of water for all restaurants is the public water supply system through taps. All restaurants equipped with sinks, 86% of sinks were supplied with soap. The majority of food handlers (89.4%) were trimmed their nails. From the interview, the main factors behind the prevalence of giardiasis were lack of awareness and poor hygiene such as: not washing hands before eating and after using latrine, low level of income, poor sanitation, and low level of education. The statistics revealed that there was a significant association between (age, family size, income/SDG, hand washing after using a toilet, residential area, existence of valid medical card ) and the infection with giardiasis with P. values (0.02, 0.03, 0.004, 0.00,0.01, 0.00). There was no association between (educational level, knowledge about giardiasis, contact with animals) and infection with giardiasis with P. values (0.45, 0.13, 0.07) respectively. Conclusion: large group of food handlers were found to be infected with giardiasis according to many associated factors as: poor awareness of personal hygiene -no hand washing with soap - and no latrines in restaurants. Therefore, the study recommended that provision of latrines in restaurants, health education programs increase the awareness about giardiasis and other diseases associated with food and food contamination.
