With the ever-increasing changes and growing scientific output in the field of food safety, it has become imperative to measure, analyze, characterize and compare existing publications quantitatively. The present study aimed to identify and analyze the characteristics of the 100 top-cited studies on food safety. Food safety articles published in the Web of Science Core Collection database between 1950 and 2020 were collected, and bibliometric parameters were assessed. Data analysis was performed using VOSviewer software to visualize linkages and establish relationships between articles, keywords, research areas, authors, countries and institutions, among others, providing insight into the most impactful studies related to food safety. This study highlights that research focused on food safety is growing rapidly globally and cuts across several fields, including biotechnology, microbiology, food processing and preservation, consumer studies, and policy development. There is a dearth of research articles in the areas of chemical contamination of foods by pesticides and other chemical residues and in food fraud detection and prevention studies.

Globally, the prevailing COVID-19 pandemic has caused unprecedented clinical and public health concerns with increasing morbidity and mortality. Unfortunately, the burden of COVID-19 in Africa has been further exacerbated by the simultaneous epidemics of Ebola virus disease (EVD) and Lassa Fever (LF) which has created a huge burden on African healthcare systems. As Africa struggles to contain the spread of the second (and third) waves of the COVID-19 pandemic, the number of reported cases of LF is also increasing, and recently, new outbreaks of EVD. Before the pandemic, many of Africa’s frail healthcare systems were already overburdened due to resource limitations in staffing and infrastructure, and also, multiple endemic tropical diseases. However, the shared epidemiological and pathophysiological features of COVID-19, EVD and LF as well their simultaneous occurrence in Africa may result in misdiagnosis at the onset of infection, an increased possibility of co-infection, and rapid and silent community spread of the virus(es). Other challenges include high population mobility across porous borders, risk of human-to-animal transmission and reverse zoonotic spread, and other public health concerns. This review highlights some major clinical and public health challenges toward responses to the COVID-19 pandemic amidst the deuce-ace of recurrent LF and EVD epidemics in Africa. Applying the One Health approach in infectious disease surveillance and preparedness is essential in mitigating emerging and re-emerging (co-)epidemics in Africa and beyond.
