In 2020, an outbreak of Salmonella Hadar illnesses was linked to contact with non-commercial, privately owned (backyard) poultry including live chickens, turkeys, and ducks, resulting in 848 illnesses. From late 2020 to 2021, this Salmonella Hadar strain caused an outbreak that was linked to ground turkey consumption. Core genome multilocus sequence typing (cgMLST) analysis determined that the Salmonella Hadar isolates detected during the outbreak linked to backyard poultry and the outbreak linked to ground turkey were closely related genetically (within 0–16 alleles). Epidemiological and traceback investigations were unable to determine how Salmonella Hadar detected in backyard poultry and ground turkey were linked, despite this genetic relatedness. Enhanced molecular characterization methods, such as analysis of the pangenome of Salmonella isolates, might be necessary to understand the relationship between these two outbreaks. Similarly, enhanced data collection during outbreak investigations and further research could potentially aid in determining whether these transmission vehicles are truly linked by a common source and what reservoirs exist across the poultry industries that allow Salmonella Hadar to persist. Further work combining epidemiological data collection, more detailed traceback information, and genomic analysis tools will be important for monitoring and investigating future enteric disease outbreaks.

Is the COVID-19 pandemic truly a pivotal moment in contemporary governance? This question has sparked multifaceted responses and spurred diverse debates and perspectives. On one side of the spectrum, there are those who ardently argue that this pandemic represents an exceedingly rare and profoundly impactful historical juncture, specifically within the domain of law and governance. In contrast, a counterpoint in this debate contends that the pandemic, rather than introducing an entirely new era, has primarily functioned as an amplifier and extension of pre-existing governing paradigms. Additionally, there is a notable contention that the pandemic has invigorated and revitalized social movements with a central focus on challenging established state structures.

La pandémie de COVID-19 représente-t-elle véritablement un moment charnière pour la gouvernance contemporaine? Cette question suscite de multiples réponses de même qu’une grande variété de débats et de perspectives. D’un côté se trouvent ceux qui soutiennent ardemment que cette pandémie constitue un événement historique des plus rares, aux répercussions profondes, notamment dans le domaine du droit et de la gouvernance. En revanche, d’autres prétendent que la pandémie, plutôt que de marquer le début d’une ère nouvelle, a principalement amplifié et prolongé les paradigmes préexistants de la gouvernance. Par ailleurs, d’aucuns affirment que la pandémie a revigoré et revitalisé les mouvements sociaux axés sur la remise en question des structures étatiques établies.

Our dominant food system is a primary driver of worsening human and planetary health. Held in March 2022, the Public Health Association of Australia’s Food Futures Conference was an opportunity for people working across the food system to connect and advocate for a comprehensive, intersectoral, whole-of-society food and nutrition policy in Australia to attenuate these issues. Conference themes included food systems for local and global good; ecological nutrition; social mobilisation for planetary and public good; food sovereignty and food equity. Students and young professionals are integral in transforming food systems, yet they are under-represented in the academic workforce, across publishing, scientific societies and conference plenaries. A satellite event was held to platform initiatives from early career researchers (ECR) in areas integral for improving planetary and public good. The research topics discussed in this commentary reflect sub-themes of the conference under investigation by ECR: food systems governance and regulation; local food policies; commercial determinants of health; sustainable healthy diets; and food equity and sovereignty.
