Microbial Food Safety at the Nutrition Interface: Impacts on Public Health Outcomes, Risk Communication, and Food System Resilience

About this Research Topic

Background

In today's increasingly interconnected food systems, the boundary between microbial food safety and human nutrition is becoming more intertwined. Foodborne pathogens such as Listeria monocytogenes, Salmonella spp., and Shiga toxin-producing Escherichia coli pose acute health risks, particularly to vulnerable populations with compromised immune systems. Viruses such as coronavirus not only cause immediate symptoms and long-term health consequences but also contribute to changes in consumer behaviors, eating habits, and exacerbate food insecurity. As the global community works to achieve nutritional and public health goals, it is critical to integrate food safety considerations into the broader nutrition and health agenda.

This research topic aims to explore the interactions between microbial food safety, human nutrition, and consumer health outcomes. While nutrition research today often emphasizes dietary quality and chronic disease—frequently based on animal models—less attention has been paid to exploring how microbial contamination of food and the risk of foodborne diseases impact human nutrition and food security.

Recent advancements in pathogen surveillance, molecular diagnostics, predictive microbiology, regulatory policies, as well as information-sharing social platforms, have improved the accessibility of food safety knowledge among consumers and food handlers, with an expected reducing effect on microbial food safety risks and a promotion of public health. Food labeling also plays an increasingly important role in shaping consumers’ behavior. Labels such as ‘Do Not Eat Raw,’ ‘Keep Refrigerated/Frozen,’ or ‘Use by’ provide direct safety guidance, while nutritional facts, allergen declarations, and origin claims (e.g., organic, locally grown, farm-raised) influence food selection decision-making and consumer nutrition outcomes. However, despite its growing relevance, little is known about the translation of these advances in food safety and surveillance into improved public health benefits, consumer safety, and more resilient, equitable food systems across regions and populations. The intersection of food safety perception, food labeling, and nutritional behavior also remains largely underexplored.

This collection seeks to highlight research that focuses on both upstream and downstream factors—ranging from food production and handling to consumer behavior and regulatory frameworks—that influence the microbial safety, human nutrition, and public health impacts of food. Through this initiative, we aim to promote interdisciplinary research that contributes to global food safety, public health, and nutrition goals.

We invite interdisciplinary submissions that explore the relationship between microbial contamination, consumer health, food labeling, and nutrition from multiple perspectives. Topics of interest include, but are not limited to:

• Surveillance of foodborne pathogens and outbreak trends, including the associated health and nutritional outcomes;
• Regulatory responses to foodborne illness outbreaks and their implications for food access and safety;
• Consumer knowledge, behavior, eating habits, and risk perception related to food safety and nutritional trends;
• The role of food labeling in shaping food safety perception, risk avoidance, and nutrition-related decision-making;
• Microbial risks in immunocompromised and nutritionally vulnerable populations;
• Innovations in food safety interventions and sustainable food processing, preservation, or labeling/packaging that preserve or enhance food nutritional quality.

We encourage original research articles, reviews, mini-reviews, and perspectives. Manuscripts that integrate food microbiology, nutritional science, public health, epidemiology, food policy, labeling practices, machine learning, or predictive modeling are especially encouraged.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
