Background: Food handlers can play a vital role into reducing foodborne diseases by adopting appropriate food handling and sanitation practices in working plants. This study aimed to assess the factors associated with food safety knowledge and practices among meat handlers who work at butcher shops in Bangladesh.Methods: A cross-sectional study was conducted among 300 meat handlers from January to March, 2021. Data were collected through in-person interviews using a structured questionnaire. The questionnaire consisted of three parts; socio-demographic characteristics, assessments of food safety knowledge, and food safety practices. A multiple logistic regression model was used to identify the factors associated with food safety knowledge and practices.Results: Only 20% [95% confidence interval, (CI) 15.7–24.7] and 16.3% (95% CI 12.3–20.7) of the respondents demonstrated good levels of food safety knowledge and practices, respectively. The factors associated with good levels of food safety knowledge were: having a higher secondary education [adjusted odds ratio (AOR) = 4.57, 95% CI 1.11–18.76], income above 25,000 BDT/month (AOR = 10.52, 95% CI 3.43–32.26), work experience of > 10 years (AOR = 9.31, 95% CI 1.92–45.09), ≥ 8 h per day of work (AOR = 6.14, 95% CI 2.69–13.10), employed on a daily basis (AOR = 4.05, 95% CI 1.16–14.14), and having food safety training (AOR = 8.98 95% CI 2.16–37.32). Good food safety knowledge (AOR = 5.68, 95% CI 2.33–13.87) and working ≥ 8 h per day (AOR = 8.44, 95% CI 3.11–22.91) were significantly associated with a good level of food safety practice.Conclusions: Poor knowledge and practices regarding food safety were found among Bangladeshi meat handlers. Findings may help public health professionals and practitioners develop targeted strategies to improve food safety knowledge and practices among this population. Such strategies may include education and sensitization on good food safety practices.

Marine fish are high in essential omega‐3 fatty acids, which are important for human health. This study evaluated the effects of four extraction methods (soxhlet extraction, SE; wet rendering, WR; acid silage, AS; microwave‐assisted extraction, MAE) on the oil yield, physicochemical properties, fatty acid profile, and nutritional quality index (NQI) of pangus fish oil. The oil yield ranged from 13.50% to 21.80%, with MAE having the highest yield. Furthermore, MAE oil has the lowest free fatty acid (0.70%), peroxides (2.08 Meq/kg), and saponification (287.27 mg/g KOH) value. There were no significant differences (p > .05) in the refractive index and melting point of oils among extraction techniques. A total of 25 fatty acids were identified. However, the maximum PUFA, MUFA, and SFA recovery was observed in the SE (19.15 mg/100 g), MAE (7.99 mg/100 g), and AS (17.33 mg/100 g), respectively. In terms of NQI, SE had higher PUFA/SFA, HH, and LA/ALA ratios, while AS had higher EPA + DHA, n‐3/n‐6, AI, TI, and FLQ indices. Furthermore, the MAE approach yielded better ratios of n‐3/n‐6 and HPI index, whereas the WR method yielded a higher AI index. Therefore, MAE would be the most efficient method for extracting pangus fish oil by considering both technical feasibility and quality indices including extraction yield, best physical properties, oxidative stability, and fatty acid contents.

Understanding the linkage between the nutrient composition of foods and individuals’ recommended nutrient intake is important to address malnutrition. Despite it being a traditional and popular food item in Bangladesh, the nutrient composition of dry fish has not been reviewed yet. This study used a narrative review to assess the nutrient composition of dry fish and estimated its potential contribution to addressing some common nutritional deficiencies among children and pregnant and lactating women in Bangladesh. Records were collected from different databases, including the Web of Science, Google Scholar, PubMed, ScienceDirect, Banglajol, and ResearchGate. Data were extracted from 48 articles containing 1128 entries regarding nutrient composition. Most of the nutrient analyses estimated the proximate composition, whereas vitamin, mineral, amino acid, and fatty acid compositions were scarce in the literature. We found that dry fish has high protein and mineral content and could contribute highly to meeting the recommended nutrient intake of protein, iron, zinc, and calcium for children and pregnant and lactating women. The summarized nutrient composition data could be useful for further research to observe how dry fish could be best utilized to address malnutrition in Bangladesh. This narrative review recommends that further nutrient analysis, with emphasis on vitamin, mineral, and fatty acid compositions.

This study was conducted to evaluate the quality features, antioxidant capabilities, microbiological and sensory aspects of yogurt fortified with 2%, 5%, and 7% red dragon (RD) peel powder. The yogurt was formulated using the classical technology adapted to laboratory conditions. The results of the physicochemical properties showed significant differences in pH (4.73–4.36), acidity (0.18–0.16 g lactic acid/100 g), and ascorbic acid (1.17-1.34 mg/100 g) among different yogurt formulations (P<0.05). In addition, RD peel powder fortification showed increasing trends in crude fiber (1.53-3.34 g/100 g), ash (5.19-5.29 g/100 g), and moisture (76.70-80.19 g/100 g) content, respectively; while the reversed trend was observed for fat (3.48-2.36 g/100 g), and crude protein (4.49-4.07 g/100 g) contents, respectively. Furthermore, gradual progression of RD peel powder in fortified yogurt manifested an improvement of the overall antioxidant activity (1.30-1.57 µmol TE/mL). The analyses of the sensory properties demonstrated that yogurt with RD peel powder in proportions of 2% received the highest hedonic score for consumer approval. Moreover, no coliform was reported in any of the control and fortified yogurts. Therefore, it could be concluded that RD peel powder can be employed as a functional food constituent in yogurt with improved quality attributes and sensory properties compared to plain yogurt.

Tea has become an integral part of our culture and everyday life due to taste, together with a refreshing and mildly stimulant effect. The study was carried out to investigate the behaviour pattern and prevalence observed due to regular consumption of tea as a source of caffeine among the university students using a self-reported validated questionnaire. Socio-demographic and data related to tea consumption pattern were collected and analysed statistically. Among 245 study participants, the majority chose a greater proportion of tea (83.7%) followed by coffee (14.7%). The main reasons for tea consumption by university students included keeping alert during the examination period (38.8%), followed by the removal of anxiety and stress. Students (around 61%) mostly consume 2-3 cup of tea per day. According to the study, 12.7% of students had never consumed tea. More than two-thirds (66.9%) of the students reported having a sound sleep, normal BMI and blood pressure, a majority of them were engaged with regular physical exercise. The study also illustrated that most of the students (52.7%) give priority to the quality of the product rather than price, brand and taste while buying packaged tea leaves. Thus, this study provides basics about the prevalence and presents a recommendation for expanding tea consumption market among the university students.
