One warning about listeria.
Most food-borne bacteria have a hard time in the fridge. They like it warmer 55 degrees upwards.
Not listeria!
Listeria is happy as a clam in your fridge, and given the right foods, etc, can multiply like wildfire. Even in the 40 degree temps of most fridges.
Anybody suspecting listeria contamination in their fridge would do well to unload it, unplug it, ans give it a good washing with soapy water and bleach.
Yikes, I didn't know that listeria could survive low temperatures. Thank you, DJF.
Thank you for that info.
