Signs half-and-half has gone bad
- A sour smell or a curdled look when it hits hot coffee.
- Lumps or separation that won't shake back in.
- A bloated or swollen carton.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.

An unopened ultra-pasteurised carton keeps a couple of weeks in the coldest part of the fridge, but once opened it sours within a few days — store it on a back shelf, never the door, and smell-test before pouring it into coffee.
