Inadequate food safety knowledge and hygiene practices among street food vendors in Dhaka, Bangladesh.

Food safety remains a critical issue with outbreaks of foodborne illness. The knowledge gap of food safety and improper hygienic practices of food handlers are the key factors for the transmission of foodborne diseases. This study was conducted to investigate the level of food safety knowledge and practices among street food vendors in Dhaka City, Bangladesh, and its implications on consumers' health. This cross-sectional study was conducted among 350 respondents in seven areas of Dhaka City. Trained data collectors gather data by interviewing street vendors using a pretested questionnaire. Most of the vendors (98%) were male, with 48% having secondary education and 85% having no food safety training. Although about 89% of the vendors were found to practice hand washing, only a small proportion of them practised using hand gloves while handling raw products (5.6%), cleaning tables (2.2%), preparing foods (1.3%) or handling garbage (0.9%). The education level of the vendors and their work experience were significantly correlated with their hand washing practice, wearing hand gloves and their knowledge about food-borne illnesses. The study demonstrated that formal education played a significant role in vendors' knowledge and practice of health safety measures for food handlers to prevent foodborne illness. Effective food safety training and monitoring are needed to increase vendors' knowledge and practices, and in reducing foodborne diseases.

Challenges for microcirculation research in developing countries.

BACKGROUND: Microvascular dysfunction is a main contributor to morbidity and mortality worldwide. Sophisticated technical tools (e.g. miniaturized hardware, automated software), along with skilled personnel are the prerequisite for quantitative observations of the microvasculature. OBJECTIVE: This review aimed to get an overview about on-going microcirculatory research in developing countries, particularly of the South-East Asia region for the last five years and to project the challenges faced in microcirculation research in developing countries. METHODS: Original research articles originating from 194 countries were searched in PubMed database on the field of microcirculation research for the last five years. RESULTS: Our findings showed that around 1800 articles have been published from developing countries compared to more than 5000 from developed countries on different aspects of microcirculation. The overall publication per million populations for developing countries was found to be 0.37 where for developed countries it was 3.62. CONCLUSIONS: Initiation and execution of sophisticated research in microcirculation is a demand of the time. Such research, initially, may seem unmanageable in developing countries with limited resources and infrastructure settings. Collaborative scientific projects may aid in establishing networks for microvascular research in developing countries.
