While people around the world are terrified of the global pandemic coronavirus disease 2019 (COVID-19) and are dying for a permanent solution, undertaking preventive safety measures are said to be the most effective way to stay away from it. People’s adherence to these measures is broadly dependent on their knowledge, attitude, and practices (KAP). People working in the food industry must be extra cautious during this time because they are in close proximity to consumable items. The present study was designed to evaluate food handlers’ knowledge, attitude, and practices regarding COVID-19 in a food industry in Dhaka, Bangladesh. A number of 155 food handlers took part in this online-based study. The information was collected from the participants through a questionnaire prepared in Google form. With a correct response rate of about 90% on average (knowledge 89.7%, attitude 93%, practices 88.2%), the participants showed a good level of KAP regarding COVID-19. However, education and working experiences had a significant association with the total KAP scores (p < 0.05). Further KAP studies in different generic food industries in Bangladesh should be carried out to bring a more precise picture for ensuring the level of workplace and worker’s safety.
