It is frothing like a rabid dog! At dinner tonight I opened a brand new bottle of salad dressing (Girard's Greek Feta Vinaigrette, expiration date 2/16/08) and noticed a slight hiss, as if there were a partial vacuum in the jar, perhaps from being chilled. We proceed to eat, and when I go to get seconds on the salad I notice that the salad dressing is bubbling away, like an opened soda or beer only in slow motion. This continued for several minutes, until I replaced the cap and put it in the fridge saying "I think we should hold off on this until we know whats going on." It is as if something had fermented; I assume the gas was CO2 but don't know. One concern was botulism, but the vinegar in the dressing makes that pretty unlikely. I plan to call the company, but they do not have a 24 hour customer service number. We didn't notice any obvious off tastes, but I have not had this particular dressing before so might not notice an unusual taste. It has been a couple of hours and we both feel fine, so it seems safe, but it was still pretty strange. Any ideas what it could be? If I can find out anything from another source I will post an update. Thanks in advance. tag:ask.metafilter.com,2007:site.73710 Fri, 12 Oct 2007 18:33:03 -0800 bubbly foodsafety Saladdressing TedW
