The workplace is a key environmental determinant of health and wellbeing. Food choices can be influenced by several workplace related factors including, but not limited to, working hours, the workplace food environment, job roles and workplace culture. Therefore, the workplace is increasingly viewed as an important place for public health nutrition interventions. However, research in this area is fragmented and heterogeneous due to the wide range of workplace settings and occupational groups. This editorial summarises the research presented at The Nutrition Society Workplace Diet and Health Special Interest Group Satellite Symposium in July 2024 as part of the inaugural Nutrition Society congress.

In May of 2018, PulseNet, the national molecular subtyping network for enteric pathogens, detected a multistate cluster of illnesses caused by an uncommon molecular subtype of Salmonella serovar Mbandaka. A case was defined as an illness in a person infected with the outbreak strain of Salmonella Mbandaka with illness onset on or after 3 March 2018 and before 1 September 2018. One-hundred thirty-six cases from 36 states were identified; 35 hospitalisations and no deaths were reported. Ill people ranged in age from <1 year to 95 years (median: 57 years). When standardised questionnaires did not generate a strong hypothesis, opened-ended interviews were performed. Sixty-three of 84 (75%) ultimately reported consuming or possibly consuming a specific sweetened puffed wheat cereal in the week before illness onset. Environmental sampling performed at the cereal manufacturing facility yielded the outbreak strain. The outbreak strain was also isolated from open cereal samples from ill people's homes and from a sealed retail sample. Due to these findings, the brand owner of the product issued a voluntary recall of the cereal on 14 June 2018. Additional investigation of the manufacturing facility identified persistent environmental contamination with Salmonella Mbandaka that was closely genetically related to other isolates in the outbreak. This investigation highlights the ability of Salmonella to survive in low-moisture environments, and the potential for prolonged outbreaks linked to products with long shelf lives and large distribution areas.

In 1969, Robert E. Gregg collected five species of ants (Hymenoptera: Formicidae) in three Subarctic localities near the town of Churchill, Manitoba, Canada, which he documented in a 1972 publication in The Canadian Entomologist. To determine whether there have been any additions to the local fauna – as might be predicted to occur in response to a warming climate and increased traffic to the Port of Churchill in the intervening 40 years – we re-collected ants from the same localities in 2012. We identified the ants we collected from Gregg’s sampling sites using both traditional morphological preparations and DNA barcoding. In addition, we examined specimens from Gregg’s initial collection that are accessioned at the Field Museum of Natural History (Chicago, Illinois, United States of America). Using this integrative approach we report seven species present at the same sites Gregg sampled 40 years earlier. We conclude that the apparent increase is likely not due to any arrivals from more southerly distributed ants, but to the increased resolution provided by DNA barcodes to resident species complexes with a complicated history. We provide a brief synopsis of these results and their taxonomic context.

This study examined the onset and acquisition of language comprehension and production in a language delayed child through the analysis of a daily diary kept from 2;5 to 3;10, in order to determine whether such data might contribute to our understanding of normal language development. The onset of both comprehension and production was substantially delayed, yet both underwent word spurts that approximated the normal rate of acquisition. The gap between comprehension and production was also greater than that found in normal children. The existence of the normal spurts was interpreted as indicating biologically determined milestones that are vital in the acquisition process. It is suggested that clinical intervention should set these milestones as goals of therapy.

Dedicated community-based services have been recommended for people with personality disorder, but little is known about how such services should be configured. We conducted a Delphi survey to assess opinions about this. A panel of expert authors, service providers and service users agreed on only 21 (39%) of 54 statements on the organisation and delivery of care. Consensus was not reached on important issues such as working with people with a history of violent offending, the role of community outreach and the use of compulsory treatment. Further work needs to be undertaken before the optimal organisation of dedicated personality disorder services can be agreed.

One child's lexical development was followed from 1; 1 to 1; 7 to look for possible causes of early word overextensions. Lexical acquisition was observed for comprehension and production through the use of a parental diary and systematic language sampling. In addition, 16 nonsense words were taught in 10 experimental sessions over a two-month period to control for phonological effects. The results isolated six distinct factors behind early word overextensions. It is concluded that overextensions should not constitute the primary data for the construction of theories of semantic acquisition.

Reported here is the development of a novel evolved gas analysis technique; Sub-Ambient Thermal Volatilization Analysis (SATVA) and its application in characterizing key analyte species from conservation artifacts. In this work SATVA has been applied to the study of volatiles evolution processes occurring in number of model conservation artifacts. The evolution of volatile species from cured formaldehyde resin, leather and metallic artifacts has been studied by SATVA. The specific analytes making up the total quantity of evolved material in each case have been separated and identified using sub-ambient differential distillation and a combination of online mass spectrometry, gas phase IR spectroscopy and GC-MS. The data gathered has been used to provide information on both the degradation processes occurring within the artifacts and the environmental history of the artifacts themselves.
