Hi Mrosinski,
You are correct about the saliva backwash into juice and milk.
Have you ever seen a bowl of half eaten pudding? It becomes watery,
especially near the spoon. This is from digestive enzymes in the
saliva that have digested the starch contained in the pudding. The
same thing happens to milk and juice.
The temperature of the refrigerator HELPS decrease numbers of
bacteria from multiplying in the lid and mik/juics, but bacterial
contamination can still be of concern. The few bacteria left on the
lid may not be of much concern, but bacteria reproduce exponentially.
In a few hours you'll have huge numbers of bacteria. It's these
multiplying bacteria and their toxins that CAN be problematic.
One can transmit an infection such as strep and staph through
drink containers. HIV and hepatitis can also be spread through saliva.
You don't drink after a family member with an infectious illness do
you?
Apart from the issue of common courtesy, it is not sanitary to
drink from a container that is shared by others. Milk and juice can go
bad much quicker once salivary bacteria is introduced into the
container. Do you and your boyfriend share a toothbrush? I hope not!
Studies have shown that this practice can spread bacteria that cause
cavities from one person to the other.
"Regardless of how water was treated and stored, measures should be
taken to control exposure to bacteria once containers are opened. To
reduce the chance of water contamination, open only the containers you
will use immediately. If electricity is available, store opened
containers in a refrigerator at or below 40 degrees Fahrenheit. Avoid
introducing bacterial contamination into the stored water:
* don't put dippers or spoons into containers
* don't drink directly out of a container
* keep container openings and lids clean "

"Messages included a variety of practices ranging from not eating
raw meat, washing off the top of cans, rejecting dented cans, and
not drinking directly from the milk carton. The game was
originally developed as an adult version from Purdue University.
We modified it to include items to which children can relate."

"Anyone who can feast on things I have seen on "Fear Factor" disturbs
me. I have an aversion to milk. When I was younger I had a very bad
experience with some milk that had gone sour. To this day I have to
throw out milk a couple of days before the date on the carton. Hell, I
only drink milk when I have cookies, cake or some other sweet
substance. The episode that happened when I was young taught me to
never drink directly from the carton though.
"i had the same experience with orange juice. it's as bad as spoiled
milk and i gagged on it. i can still drink it, but damned if i'm going
by the expiration date again.
if you don't know what oj's like when it's gone bad, you probably
can't appreciate this."
