Dapple wipes - is the milk okay?

Ughhh I’m so paranoid! I had to use dapple wipes at work and felt like I wiped my wearables down pretty well, but when I went to put it back together for my next pump there was residue. I’m a teacher so I don’t have any time to waste when pumping during the day, so I just threw them together and pumped. Is that milk going to be okay?? I suffer from PPA, so im not sure if this is a legitimate concern or just my anxiety. Thank you for your help!

ETA: also - the milk i pumped isn’t staying very cold in my cooler or on my super old mini fridge. Is that going to be okay until I can get it home and in the fridge? My first pump was around 7am and I’ll get home around 3:45.
