The fat is turning green. Is that bad? It looks bad. I don't need to flip them at all?
Is it Green fuzzy Mold or the fat actually turned green? Nitrite Burn is no issue. Green mold on wet cured, brined meats, is bad, penetrates deep into the meat, but on Dry Cured bacon there is less to worry about as it is on the surface and can be washed off. Either way, wash it, fry a piece and taste it. You will know if it is spoiled riht away. While Black Mold is Bad News Bears, Blue, Green and White are common in refers and are rarely an issue unless eaten in large, one sitting, quantities or by sensitive people...JJ
