I don't worry about that because humans normally have many beneficial bacteria in the intestine already. I am also blessed to have been free of any kind of intestinal problems for all of my 64 years, with the exception of an occasional intestinal virus. Safer sources of beneficial bacterial would be some varieties of pasteurized milk, yogurt, or Activia.

Pasteurization kills all of the bacteria in milk, including beneficial bacteria. So that eliminates it as a source of beneficial bacteria. Some yogurt is a good source, if it has active cultures. I eat yogurt occasionally, but I don’t know how anyone can eat it every day.

Mass produced food requires certain procedures which aren’t healthy, but are necessary to maintain costs. That fine, if that’s what you want. I usually choose that route myself. But there are times when I’d rather spend more and get healthy food. Milk is one of those things I splurge on. I love real milk; the taste, the texture, and what it does for my body. If I could afford to be that picky about all of my food, I would be.
