Manuka honey always has a measure of antibacterial activity labeled on the bottle. However, the numbers can be confusing, because there are different measurement systems in use.

One of the most common is MGO (or methylglyoxal). MGO is a globally recognized measure of antibacterial activity.
Another system that you might see mentioned on honey jars is "UMF" (a scheme created in New Zealand). Berringa uses proven MGO measurement methodology to rate our range of 100% Australian Manuka honey and we verify actual MGO levels for each batch through independent testing in Australian government NATA accredited laboratories (which also means that You can be sure that the MGO level listed on the outside of each Berringa can is accurate).
