Evaluation of food safety in the handling of home enteral nutrition based on a new contamination risk classification: A cross‐sectional study

Nutrition in Clinical Practice, EarlyView.
Abstract Background Home enteral nutrition (HEN) offers clinical benefits and is increasingly used, although handling‐related health risks remain unclear. This study assessed food safety in HEN using a new contamination risk classification. Methods First, the inter‐rater reliability of the Food Safety for Handling HEN checklist was analyzed in 25 ...

Consistent Collaborative Vehicle Utilization

Networks, EarlyView.
ABSTRACT Carriers are often reluctant to collaborate with other carriers in delivering goods to customers despite potential cost reductions. A durable collaboration requires attention to more aspects. Carriers typically wish to remain competitive, unconstrained by the collaboration, increasing profits by attracting new customers and withholding ...

How uneven access shapes the socio‐economic and environmental potential of game meat value chains: The case of legal game meat in Zambia

People and Nature, EarlyView.
Abstract Game meat contributes to human nutrition, food security and sociocultural practices around the world. Game meat also comes with risks, including overharvesting and zoonotic and food‐borne disease. These may be pronounced where game meat travels along complex value chains from rural to urban areas.

Capacity and limitations of US wild meat donation programmes

People and Nature, EarlyView.
Abstract Historically, sharing of wild harvests to facilitate food security followed concepts of kin selection and reciprocal altruism. However, cultural shifts have reduced access to foods for some populations in modern times. Cultural altruism through sustainably harvested wild meat donation programmes (WDPs) can reduce food and nutritional ...

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.
