Leveraging risk assessment for foodborne outbreak investigations: The Quantitative Risk Assessment-Epidemic Curve Prediction Model

Root cause analysis can be used in foodborne illness outbreak investigations to determine the underlying causes of an outbreak and to help identify actions that could be taken to prevent future outbreaks. We developed a new tool, the Quantitative Risk Assessment-Epidemic Curve Prediction Model (QRA-EC), to assist with these goals and applied it to a case study to investigate and illustrate the utility of leveraging quantitative risk assessment to provide unique insights for foodborne illness outbreak root cause analysis. We used a 2019 Salmonella outbreak linked to melons as a case study to demonstrate the utility of this model (Centers for Disease Control and Prevention [CDC], 2019). The model was used to evaluate the impact of various root cause hypotheses (representing different contamination sources and food safety system failures in the melon supply chain) on the predicted number and timeline of illnesses. The predicted number of illnesses varied by contamination source and was strongly impacted by the prevalence and level of Salmonella contamination on the surface/inside of whole melons and inside contamination niches on equipment surfaces. The timeline of illnesses was most strongly impacted by equipment sanitation efficacy for contamination niches. Evaluations of a wide range of scenarios representing various potential root causes enabled us to identify which hypotheses, were likely to result in an outbreak of similar size and illness timeline to the 2019 Salmonella melon outbreak. The QRA-EC framework can be adapted to accommodate any food–pathogen pairs to provide insights for foodborne outbreak investigations.     

Civic Engagement and Latina Immigrant Mothers' Remote Learning Involvement During COVID-191

Immigrant incorporation scholars have established that racialized immigrant parents encounter several barriers in their children's schooling: namely, language and cultural differences, discrimination, unfamiliarity with the U.S. schooling system, and unhelpful school agents. However, less is known about the mechanisms that lessen these challenges. Drawing on insights from immigrant incorporation and civic engagement literature, this study examines how advocacy organizations can mediate the barriers racialized immigrant parents face in their children's schooling. A case study of 20 Latina immigrant mothers is used to demonstrate how civically engaged parents drew on their participation with a local advocacy organization—Parent's Choice—to overcome the barriers that emerged during the transition to remote learning due to the coronavirus disease 2019 pandemic. Findings suggest that immigrant mothers leveraged their connection to Parent's Choice to learn how to use technology, get district-related updates, secure devices necessary for at-home learning, create complaints or demands for services at their children's school, fill out paperwork, and access community-based referrals. Parent's Choice provided support and empowered Latina immigrant parents by minimizing the overwhelming barriers they faced during online learning. These findings complicate our understanding of immigrant civic engagement patterns and provide implications of how civic engagement can facilitate the incorporation of marginalized parents in educational institutions.     

On not ‘being there’: Making sense of the potent urge for physical proximity in transnational families at the outbreak of the COVID-19 pandemic

This paper investigates transnational families’ experiences of the COVID-19 pandemic outbreak and the accompanying sudden and unexpected travel restrictions. Our data consist of written stories collected in April–June 2020 from migrants with ageing kin living in another country. For many respondents, the situation provoked an acutely felt urge for physical proximity with their families. By analysing their experiences of ‘not being there’, we seek to understand what exactly made the urge to ‘be there’ so forceful. Bringing into dialogue literature on transnational families with Jennifer Mason's recent theoretical work on affinities, we move the focus from families’ transnational caregiving practices to the potent connections between family members. We argue that this approach can open important avenues for future research on families—transnational or otherwise—because it sheds light on the multisensory and often ineffable charges between family members that serve to connect them.
