Gilui Mashkin (Uncovered Beverages)

Gilui Mashkin Rabbi, I wanted to ask about gilui mashkin (uncovered beverages). If I was in a room and there was an uncovered cup next to me, and I was reciting Kriat Shema with my eyes closed, does the beverage become forbidden because it was uncovered? And if I am tidying up the room and there is an uncovered cup there, does the beverage become forbidden? Is it acceptable as long as I am in the room, even if I am not right next to the cup? Thank you very much in advance.

Shalom u’vracha 

According to the basic halacha, in our times there is no prohibition of gilui mashkin. 

Those who are stringent about this are strict only when there is no person present in the room.
