How do you know when almond milk goes bad?

Drank some 14 day old (open date) Silk chocolate last night & puked within minutes. It did not look, taste or smell weird. Spoil dates for almondmilk search led me to this older thread. Had coffee a bit ago with Silk creamer that will be on 7 days tomorrow. Stomach upset again, but not as severe as last night. I've had Kroger brand almondmilk that was similar age & have been fine. Maybe it depends on brand? Idk but I'll never forget to write the date on the carton again!

Yep, I keep a Sharpie in my kitchen drawer for just this reason. The expiration date on almond milk (or soy, coconut, etc.) can be confusing because if I understand it correctly it means it will stay good until that date as long as it is NOT open. Once it's opened then the 7 - 10 day window applies.

Omg I had no idea there was a "use by this date when opened". I've 100% not drank my half gallons of almond milk within 7-10 days. I thought the use by date was for when it was open or sealed! I guess I might be using spoiled almond milk in my smoothies ugh yuck

Food going "bad" is just the bacteria in it growing enough to start converting the nutrients into biproducts you wouldn't want to injest. This is usually accompanied by a change in smell, taste or texture.

I wish that were the case. Bacteria that make you really sick often don't produce any visible change. This is especially true in cooked foods. Raw food like raw meat, milk, fruit, veg - when it goes off, it goes nasty, so if it looks fine, it likely is fine. But eg cooked meat or leftover cooked food you have to be much more careful with.

This question re the almond milk is interesting. Sounds like it may be one of these stealth-spoiling foods. I'd stick to the 7-10 days. The longer expiry date only applies before you open it.

Is this the oldest resurrection? June of 2011?

So don't laugh at me or anything but im bad at these things...i have the vanilla sweetened almond milk and it says on the box "use within 7-10 days of opening but there is an expiration date on it that says mid july! Soooo.....to be on the safe side i just wanna know....does it get sour like regular milk? How long do you drink yours for?

It gets chunky when it is old and smells bad. If it still smells good and everything you can probably still drink it.
