Q. (See above question 2283). Does it make a difference if the food and drinks kept in a hospital room when the patient died there, where still sealed or where covered?
A. As mentioned in prior question, on food there is after the fact no concern even in a cemetery, following most Poskim, especially if the food was covered. On drinks Gesher Hachaim (3: 3: 11) is lenient when kept inside a closed bottle. Some Poskim require a sealed bottle (Beis Dovid 181) or at least a well stoppered bottle. (See Nitei Gavriel- Avelus (1: 8: 16; n. 30).
Poskim also permit water that carries an added commercial name, such as soda-water or mineral-water or has been changed by boiling or mixed with flavoring agents. (Beis Yitzchok Y.D. 150, Maharsham 3: 375, Divrei Malkiel 2: 94 and others).
Horav Shlomo Miller’s Shlit’a opinion is similar.
