The study aimed to identify different molds that grow on various food surfaces. As a result, we conducted a case study for the detection of mold on food surfaces based on the “you only look once (YOLO) v5” principle. In this context, a dataset of 2050 food images with mold growing on their surfaces was created. Images were obtained from our own laboratory (850 images) as well as from the internet (1200 images). The dataset was trained using the pre-trained YOLOv5 algorithm. A laboratory test was also performed to confirm that the grown organisms were mold. In comparison to YOLOv3 and YOLOv4, this current YOLOv5 model had better precision, recall, and average precision (AP), which were 98.10%, 100%, and 99.60%, respectively. The YOLOv5 algorithm was used for the first time in this study to detect mold on food surfaces. In conclusion, the proposed model successfully recognizes any kind of mold present on the food surface. Using YOLOv5, we are currently conducting research to identify the specific species of the detected mold.

More than 60% of those affected are aged between 21 and 50 years, but disproportionately 40% of deaths are in the over 60 years age group. 2 The World Health Organization has confirmed the local transmission of the virus in Bangladesh. Approximately 1 million Rohingya refugees fled from Myanmar and have been crammed into 34 refugee camps in the Cox's Bazar area since 2017. Food and water are not sufficient, and sanitation and health facilities are poor. An ideal environment for the virus to spread exists in these densely populated camps as the 40 000 refugees per square kilometer make it impossible to maintain social distancing. 3 Patients with diabetes, cardiovascular diseases, or asthma have a greater comorbidity rate compared with others. 4 More than 40% of the Rohingya refugee community are between 18 to 59 years old. 5 A high proportion of Rohingya people are suffering from noncommunicable diseases. Fear and misinformation about coronavirus disease 2019 (COVID-19) may make the situation worse in the camps due to the current telecommunication blockage, minimal Internet access inside the camp area, and illiteracy of the Rohingya people. The most worrying public health issues are food safety and shortages, and overall security. More than half of the Rohingya population face water supply shortages, and >30% of households do not have even access to soap. The shortage of food may reduce immunity against the virus, especially for women and children. In the Cox's Bazar district, the only test facility is currently provided by the Cox's Bazar Medical College, and it is unrealistic that Rohingya people will have easy access to testing and treatment facilities. Collaboration in overcoming these shortages is needed between the leadership of the local authority, the office of the Refugee Relief & Repatriation Commissioner, the Water Sanitation and Hygiene programs of United Nations High Commissioner for Refugees, and local health sectors. Infection prevention and control training and provision of personal protection equipment are required for health care workers. Food and portable water distribution systems need to be greatly improved, and the camps should be reconfigured to avoid crowding. Health workers need to identify pregnant, elderly, and comorbid patients so their special needs can be met. Isolation of cases and tracing of contacts would be the best response, although very difficult given the physical circumstances of the camps. It is important to undertake these public efforts as continuing COVID-19 infections among the Rohingya population may make it difficult to control the virus throughout Bangladesh.

The coronavirus disease 2019 (COVID-19) poses significant risks to health in the workplace for employees in the manufacturing sector of Bangladesh. A variety of preventive steps are being taken by many food industries to sustain their production during this period by ensuring food safety. In response to the current outbreak, early identification, preparedness for the growing threat, and employee well-being are of utmost importance. Food health is also a concern in this regard, as workers in the food industry remain close to food and packages. The risk of spreading the virus within the industry can be held to a minimum with timely action and concerted efforts. A study was carried out in one baking industry of Bangladesh to investigate their regular activities during the pandemic period. Until the writing of this report, there were no cases of COVID-19 among employees. Thus this case study shows how one baking industry in Bangladesh prepares and responds to the COVID 19 outbreak.
