From the Research

Breast pump equipment should not be sanitized solely through dishwasher sanitization as a single step, but rather through a combination of washing and sterilizing, as evidenced by the most recent and highest quality study 1. When considering the sanitization of breast pump equipment, it is crucial to prioritize methods that ensure the removal of harmful bacteria and viruses to prevent infection and maintain the quality of life for the infant.

  • The study published in 2023 1 compared and evaluated the efficacy of different breast pump cleaning techniques for bioburden reduction, concluding that cleaning breast pump parts in hot soapy water followed by disinfection in boiling water ensures complete decontamination of the breast pump.
  • This approach is supported by the fact that boiling water removes bacteria to a level where no residual contamination is observed, making it a reliable method for sanitizing breast pump equipment.
  • While dishwasher sanitization may be effective in killing harmful bacteria and viruses, it is essential to follow the manufacturer's instructions and ensure that the parts are labeled as dishwasher-safe to prevent damage or degradation.
  • Alternative sanitization methods, such as boiling in water for 5 minutes or using a steam sterilizer designed for baby products, can be used for parts that are not dishwasher-safe.
  • It is also important to note that the microbiological quality of the rinse water is a critical consideration, particularly for infants on neonatal units, as highlighted in the study published in 2016 2.
  • Ultimately, the goal is to minimize the risk of infection and ensure the safety and quality of life for the infant, and therefore, a combination of washing and sterilizing is recommended for sanitizing breast pump equipment.
