Microbiological safety in the reuse of materials in home enteral nutrition: A quantitative in vitro experimental study

Nutrition in Clinical Practice, EarlyView.
Abstract Introduction In home enteral nutrition (HEN), the reuse of packaging and administration materials beyond the recommended period, combined with inadequate hygiene practice, increase the risk of microbiological contamination. This study assessed the risk through a simulation that reproduced real‐world usage conditions and hygiene practices ...
