During my move to a new home a 10lb bag of granulated pure cane sugar had some vegetable oil drip onto it. After 2 days when I observed that I took the sugar out of its paper bag and put it into a large zip-lock plastic bag that appears to be airtight. Is the sugar safe and for how long? How can I tell if it goes bad?

  • What do you mean by "goes bad?" Is the sugar dry now, or is it moist with oil?

  • By "goes bad" I mean it would be potentially hazardous to eat. The sugar is dry I would guess, the part with oil got mixed in with the rest of the 10lbs of it when I put it in the plastic bag so it is hard to check that specifically. May 5, 2020 at 20:31

I don't see a safety risk. Oil can go rancid. That is a quality issue, rather than a safety issue. Moist sugar could potentially mold, I suppose. If you see mold forming I would discard. Otherwise, this seems like a low risk situation to me.

  • Thanks! I will be sure to watch out for those things. I appreciate your help. May 7, 2020 at 1:51
