“…The concentrations of chloroform, bromoform, dibromochloromethane, and bromodichloromethane remained low in the different milk bottles after decontamination with a properly diluted CS. Total THM levels were below the toxic threshold regardless of milk volume in decontaminated bottle (20).…”

“…Atkinson and Begg (36) demonstrated that lipid content was a determining factor in the variability of THM content in both human and cow's milk (36). We did not consider this factor, but the rapid clearance of THM makes such an assessment difficult and reduces the exposure anyway (20). It is also a protective element against the risk of contamination of small volumes of breast milk production in the first few days after birth because of the low lipid content of colostrum and early lactation milk (38).…”

“…Previous studies have reported that when simple hygiene rules were followed for breast milk expressed, there was a decreased risk of contamination (24,25). Recently, it has been shown that appropriate decontamination of breast pump milk collection kits was critical to obtain safe milk for infant and to avoid discarding donor human milk (20). Actually, most of preterm babies are fed by their own mothers' milk (26), which is not pasteurized, therefore increasing the risk of microbial contamination.…”

“…It was demonstrated that steam decontamination using a microwavable bag after washing resulted in a lower proportion of discarded DHM (1.3 vs. 18% p < 0.001) (20). French Food Safety Agency therefore recommended sterile single-use or autoclavable sterilized or bacteriological clean breast pump milk collection kits for mothers in hospital.…”

“…THMs are chloroform, bromodichloromethane, dibromochloromethane, and bromoform. These compounds can arise from disinfection products when chlorine interacts with organic matters such as the ones present in the maternal milk (20). The maximum threshold accepted for total THM in drinking water in France has been set at 100 µg/l (TDI of 150 µg/kg of body weight) (decree of 11th January 2007 relating to the limits and references of quality of raw water and water intended for human consumption modified by the decree of 9th December 2015 and the decree of 4th August 2017).…”

To promote breast feeding and breast pumping is essential for the most vulnerable infants even if the current coronavirus disease 2019 (COVID-19) pandemic sanitary crisis imposes more stringent hygienic measures. As recommended by the Centers for Disease Control and Prevention, World Health Organization, and Milk Bank Association, “after each pumping session, all pump part that come into contact with breast milk should be appropriately disinfected.” The present study proposed different methods than can be used and focus on the safety analysis of chlorine solution (CS) in terms of residual hypochlorous acid (HCA) and total trihalomethanes (THM). We also performed an efficacy testing of the CS approach to decontaminate the devices used to collect the milk (breast pumps and bottles). The bacteriologic results of 1,982 breast pump milk samples collected in three different settings showed a major decrease of the microbial contamination using either sterile device or decontamination with CS compared to a simple soap washing. The main messages from our study are to propose a guideline for the safe use of CS and to define situations when breast pump decontamination might be necessary: vulnerable babies for which sterile device is recommended; special circumstances, for example the current COVID-19 pandemic; special situations, for example women living in precarious conditions; or women pumping their milk at work but that would have low or no access to boiled water. Overall, cold decontamination reduced losses of milk for bacteriological reasons in human milk banks and may also be interesting to prevent horizontal contamination by virus like COVID-19.
