Aim To determine the safety, operational feasibility and environmental impact of collecting unopened non‐perishable packaged hospital food items for reuse. Methods This pilot study tested packaged foods from an Australian hospital for bacterial species, and compared this to acceptable safe limits. A waste management strategy was trialled (n = 10 days) where non‐perishable packaged foods returning to the hospital kitchen were collected off trays, and the time taken to do this and the number and weight of packaged foods collected was measured. Data were extrapolated to estimate the greenhouse gasses produced if they were disposed of in a landfill. Results Microbiological testing (n = 66 samples) found bacteria (total colony forming units and five common species) on packaging appeared to be within acceptable limits. It took an average of 5.1 ± 10.1 sec/tray to remove packaged food items from trays returning to the kitchen, and an average of 1768 ± 19 packaged food items were per collected per day, equating to 6613 ± 78 kg/year of waste which would produce 19 tonnes/year of greenhouse gasses in landfill. Conclusions A substantial volume of food items can be collected from trays without significantly disrupting current processes. Collecting and reusing or donating non‐perishable packaged food items that are served but not used within hospitals is a potential strategy to divert food waste from landfill. This pilot study provides initial data addressing infection control and feasibility concerns. While food packages in this hospital appear safe, further research with larger samples and testing additional microbial species is recommended.
