Introduction: As the importance of breastfeeding is emphasized to educate mothers, private or online sale of human milk has been increased because of various reasons including environmental and biological factors such as allergenic reaction to the milk powder, problem of breastfeeding, and health problem of infants or mother. However, the lacking of microbiological standard in human milk traded in online market can be the great health risk in infants.

Purpose: The aim of this study was to evaluate microbiological safety in human milk sold from online market.

Methods: Eighty five human milk samples were purchased from online market. Sixty two human milks and 23 human milks were obtained by direct or online purchase. Total bacteria, coliforms, Escherichia coli, Salmonella spp., Staphylococcus spp., and Streptococcus spp. were monitored in each human milk sample. The contamination level of each microorganism was analyzed according to purchased route.

Results: Total aerobic bacteria and coliforms was ranged from zero to 5.6 log CFU/ml and from zero to 4.0 log CFU/ml in 85 human milks, respectively. Two human milks were contaminated with 2.8 and 3.6 log CFU E. coli/ml. Detection range of Staphylococcus spp. was zero to 4.7 log CFU/ml in 64 human milks. Neither Salmonella spp. or Streptococcus spp. were detected in human milks. While the detection rate of each microorganism between direct and online purchase was not significantly different, the contamination level of human milks purchased from online was higher than that of human milks obtained by direct purchase.

Significance: This study confirmed that the contamination of E. coli and S. aureus was the major microbial risk of human milk traded in online market.
