Starbucks

This may be a total blind spot for me, but it did not occur to me before now that my daily latte habit at Starbucks might be a problem. I guess I assumed the steam process in the espresso maker was hot enough, but now realize I don’t really know and in trying to find information on it, came up empty handed. I drink a soy latte most days but in addition to the espresso, there is the steamed soy milk. The soy milk itself contains quite a bit of water as part of the manufacturing process, is this safe? Where does one safely draw the line when eating and drinking outside the home? Even inside the home, is all processed food suspect and need to be cooked at a certain temp for a certain amount of time? I am specifically referring to NTM but obviously all of us with BE need to be careful re bacteria and molds generally. Interested in others thoughts and practices in this regard. Thanks.
