yogurts and green stuff

the big yogurt can (2.5 qt) is not yet empty and still has 2 weeks time left on the label... and has been refrigerated since opened.. but i see small green colored stuff on the top of the inside of the can.. is this mold?

any thoughts if this is safe or just this yogurt wasted before its time on the label?

the expiration date is referring to the unopened container, if you are referring to the liquid that forms on top the yogurt, this is normal.  if it looks like green hair or looks really funky, throw it out.  if in doubt, throw it out

If you choose to eat it and then get sick, then I would venture to say that it is green mold. If you have a microscope, you can take a look at a smear and check it out.

You can save money by easily making your own yogurt. You don't even need a yogurt maker - a pot and a good blanket to keep the heat in is all you need. (I actually got an inexpensive model good for 7 cups because of protests from my family - but from first-hand experience, it is not necessary). You just need to buy one plain yogurt for the starter bacteria (make sure the yogurt container says active culture; then save from each new batch 1/2 cup to act as the starter for the next batch. You can make 4-5 batches.)

The official USDA recommendation on yogurt mold is to discard it.

makes good sense.. thanks.
I was surprised that the official recommendation for hard cheeses and firm fruits was to just cut an inch off. Kudos to the USDA for not being wasteful and overcautious.
