Australian Honeys Demonstrate Potent Antimicrobial Activity

A study published in MicrobiologyOpen tested 56 honey samples from over 35 New South Wales apiaries against Staphylococcus aureus and E. coli. More than 75% of samples inhibited bacterial growth at dilutions of 10% or less, with mixed-floral native honeys showing greatest potency linked to hydrogen peroxide, plant phenolics, and antioxidants. Results indicate floral diversity and bee health enhance honey's potential for topical antimicrobial use.
