Is it safe to eat a dish made with vinegar if the vinegar lid had black stuff on it? I stored some vinegar in a salsa container. When I opened it, I noticed some black stuff under the lid. The vinegar liquid looked good, so I used a little and started to cook with it. When I washed the lid, the black stuff under the lid dissolved. Is my dish safe to consume?
The &quot;black stuff&quot; is most likely mold. I have found it under the lids of many foods I preserved and ate without suffering any adverse health consequences, including various vinegars.
