Nutritional drinks and enteral feeds promote the growth of Carbapenemase-producing Enterobacterales in conditions that simulate disposal in hospital sinks.

Nutritional products support CPE growth under in-vitro conditions. The propensity of CPE to survive in drain pipework suggests that inappropriate product disposal, may further nourish established CPE in these environmental reservoirs. The growth observed in diluted NSDs and ETFPs signals that modifiable practices should be optimized to mitigate potential CPE transmission risk from these reservoirs.
