I already did a google search but could not find anything.
I have some expired yogurt (about a few weeks ‘done’). Instead of just throwing it down the bin, is there a way I can reuse it? Fertilizer? Animal feed?
If it wasn’t that overdue, there were suggestions to use it as facial cream. Unfortunately, I’m a guy and I don’t do facials.
Those dates are really more “guidelines” than hard-and-fast predictions of when something will spoil. Basically a way for the producer/supplier to cover his/her ass. Is it still sealed in the container, never opened, and always refrigerated? Open it up, if it looks and smells like normal yogurt (which I’m sure it will) it’s perfectly fine to eat. Things like yogurt, sour cream, buttermilk, etc are essentially just carefully spoiled milk - they’re already “bad” the day you buy them. Personally I trust my eyes, nose, and tongue to detect spoiled foods a lot more than some date on a can.
If it’s the sort with a foil or plastic membrane lid, if it’s bulging be cautious. Otherwise taste it - it’s probably fine.
Not if it has an ugly green mold growing on it. Otherwise it might be slightly sour but ought to be fine.
Make biscuits. If it’s a little sour, it’s just more like clabber.
I’ve eaten yogurt that’s more than a year past it’s “best by” date, and it was delightfully tangy and flavorful.
When that stuff goes bad, you know it. I don’t need freshness dates to tell me that.
My cats love to eat it, regardless of expired dates. And they never seem to get sick from it.
Yeah, but you eat Vegemite. And cheese that smells like feet.
If you leave it alone long enough, will it eventually turn into cheese?
Assuming it’s not molded or bubbly, I’d either cook/bake with it, give it to the dogs or throw it out. If it smelled and tasted normal, I’d eat it - is the expiry date “eat by” or “sell by”? I imagine you have quite a bit of latitude with the “sell by” date. Maybe not as much with an “eat by” date.
(Men can have facials too, y’know. 
That said, I’m female and no, I don’t see the point of slathering yogurt on my face.)
And salty licorice, too!
Seriously, I tend to prefer the very aged cheddars over the smear cheeses like limburger and similar.
But assertive yogurt is good. And ‘best used by’ dates don’t relate much to whether the food has spoiled or not.
Another vote for: Taste it, and if it’s not offensive, eat it.
“Best if used by …” is not the same as “Probably lethal if consumed after …”
make a nice curry with it. see the recent thread on curry paste for some suggestions.

My ex-inlaws are importers of some of the fanciest cheeses and other dairy products including specialty yogurts you can get in the U.S. They run a side business that is a farm with pigs that eat mainly whole truckloads of product that can’t sold because of dating and other things. They are some of the best fed pigs you will find anywhere and they never get sick from it although I have eaten from their allocation as well and never had any ill effect either.
It really depends on how much of a pig you fancy yourself. Like others said, truly bad dairy products are self-apparent to anyone with a nose and eyes. The dates listed on them are sell-by dates for the retailer anyway and not consumer discard directives. Yogurt isn’t especially perishable as far as dairy products go as long as it is kept at a stable temperature. It is already spoiled by design. The goal is to keep it stable.
Both of these are good points, although seemingly contradictory. 
Wasn’t there some comedian who used this in his routine?
“How can yogurt have an expiration date? I mean, after it is sour milk, what else can happen?”
Mixed with white cement or lime, will make a pretty high quality marble (stone) mortar for repairing decorative hard stonework.
In the past ceramic tile adhesives were made with cement and casein base, though modern adhesives are better for several reasons.
If you have dry skin on your arms and legs, you can make a pretty good treatment for it by adding 1/2 as much oatmeal you’ve run through a food processor to the yogurt, and coating your legs etc for 5 minutes before a shower.
