A significant proportion of foodborne diseases arise from practices in home kitchens. Not only how food is handled but also how it is stored determines its safety. The current study aimed to assess knowledge and practices of households related to storage of foods in refrigerator and identify key messages to promote safe storage practices. A cross-sectional study employing mixed methods (combination of quantitative and qualitative methods) was carried out among households who owned refrigerators. Quantitative data on knowledge and practices were collected from women (n=120) who were responsible for cooking and storing foods at household level using a pretested questionnaire and qualitative data on status of the refrigerators was collected using non-participant observation technique. Leftover foods stored in refrigerators for > 24h were collected from a sub-sample (n=18) to assess the presence of food pathogens. Over 34.2% preserved leftover non-vegetarian foods at room temperature. About 65% stored leftover foods in refrigerators for >24h. Only 10% cleaned the refrigerator every week and about 20% had knowledge of the working temperature of the refrigerators. There was a significant association (P<0.05) between education and knowledge as well as practices among households. Salmonella spp. (44.4%), E. coli (27.7%), fecal coliforms (11.1%) and S. aureus (5.5%) were detected in refrigerated leftover foods. Observational studies revealed some risky storage behaviors. Most of the households are not aware of the safe storage and refrigeration practices. The detected foodborne pathogens in refrigerated leftover food samples indicate a potential hazard in refrigerated foods. The study identified five key messages for food safety communication.Keywords

Weightlifters involve in intense strength and resistance training, thus calorie adequacy is a nutritional concern for them. Determining Resting Metabolic rate (RMR) is important to assess energy needs and there is limited scientific evidence in this area. Thus, this study aims to document physical characteristics and RMR of Indian junior weightlifters. It also attempts to identify suitable RMR prediction equations by developing new equations and comparing measured with predicted RMR from seven equations already existing world-wide. In this cross-sectional observation study, twenty one Indian junior weightlifters (Boys = 9; Girls = 12) were assessed for body composition (skinfold technique) and RMR using indirect calorimetry. Regression models for RMR were developed and measured RMR was compared with predicted RMR using paired samples t-test. The 24-hour RMR showed significant (P<0.01) gender differences (Boys = 1675 ± 111.7; Girls = 1425 ± 93.4), whereas, RMR per unit fat-free mass and body mass were similar across gender. The simple equation developed using body mass (RMR = 1206 + 13 × Body Mass (Kg) – 227.7 × Gender; R2 = 0.872; SEE = 60.604) showed good agreement with measured RMR. Out of seven existing RMR models, the equation of ten Haaf and Weijs (2014) showed better predictability. In conclusion, fat-free mass caused a major variation in RMR. Considering the limited scientific evidence, prediction equations newly developed and RMR equation of ten Haaf and Weijs (2014) can be used for periodical monitoring of RMR.Keywords
