Ok, in the name of science I brought my refrigerator thermometer with me. It is the one I keep in my fridge back home, and it is pretty good, and very accurate.
We are at Caribbean Beach, with the glass-front “drink cooler” style unit. There is a sticker that clearly says that the unit only cools to 41 degrees.
When we got here the unit was empty, and the temperature was about 45. I cranked it all the way down and loaded it with some items we brought in a cooler. A couple beers, two small splits of champagne, some Costco protein shakes, and I put two Brita pitchers with tap water from the hotel in the unit.
By the next morning the unit was at 39 degrees. It has varied from 37 to 41 degrees with, for the most part, it being below 40. I haven’t seen it yet under 37, but, with stuff in it, and the door being shut, it seems to remain below 40 degrees.
Because I don’t sufficiently value the health of my family, I would easily keep foodstuffs in this fridge. Especially “hardier” items like lunch meat, etc. I don’t think it is routinely above 40 for any 4 hour period.
Take it for what its worth, but I think that with THIS unit at least, most food would be safe for the duration of time you are in this room, and for the volume and types of foods you might have in the unit.
I’m not a food scientist, and I don’t play one on TV, so your mileage may vary, and, ya know, do what you think is best…
