So what is Hojicha tea? Good question. Well, Hojicha tea is a roasted tea that is more mild and has less caffeine. The roasting process makes the tea leaves reddish in color and gives the tea a ' a toasty, slightly caramel-like flavor'. Because of the lower caffeine level, it is often served with dinner.
So how would Salmonella get in the Hojicha? Another good question. If the tea supplier was responsible, and being the leaves were roasted, it would have to be a case of cross contamination in the post-roasting environment.
