I just put some ready made mashed potato’s - the tesco finest mashed in a pot on the stove. I tried to mash it, it was quite thick so I added milk. I’m not sure if I heated it long enough but it stirred through and wasn’t clumping. It didn’t feel hot to taste but warm. Worried about the listeria risk…I did burn some milk on the bottom of the pot, only thing is I’m not sure if all the mashed potato’s were that hot.
Anyone have any advise for listeria panic?
