Our prehistoric ancestors may not have worried about it, but for centuries, modern societies have strived to keep bacteria out of their food. Now, suddenly, bacteria in food seem to be a good thing, and probiotics are becoming so popular, that eventually, consumer complaints about contaminated food, may become a thing of the past. Finding bacteria in food will be a cause for celebration, not concern, and consumers will see no reason to complain, since they will assume that the bacteria were intentionally added, for health benefits. In a strange twist of fate, consumers will learn to pay more, for contaminated food.
