I wouldn’t be so sure of that, nor is it of much significance. It’s very common in the US. A 30 to 40% colonization rate is extraordinarily high. The most common human bacterial colonization known. It was only discovered about 30 years ago and its precise method of transmission is still unknown.[/quote]
The only place on earth with a lower rate is Australia at 15%.
we know transmission is food borne. And in the US food sanitation still beats other areas on earth.
you go from an area with 1/3 prevalence rate to an area where 90% of the population has the bacteria and we are debating whether the bacteria is picked up here within the US or overseas?
