4 hours max in the zone between 40 and 140F is the general guideline for risk. There are a lot of nuances to it like how pasteurization and sous vide cooking work but in general that’s a good rule of thumb
Also to note that's only if you're gonna continue to store it.
Food left out for more than four hours is safe to consume like pizza but if you're not gonna finish it, trash it at that point you cannot store it anymore.
This is incorrect
4 hours is the safe to consume cutoff per other agencies (like the center for food safety in the uk) but they agree foods that spent more that 2 hours in 40-140F shouldn’t be refrigerated, even if still safe to eat

The usda is far more conservative. Same basic guidelines but food should be refrigerated within an hour and discarded after 2. Dunno if this is reflective of changes in quality in the food supply or just more concern for liability

Will you get food poisoning if you eat 6 hour old pizza? Frankly almost certainly not, but it depends on a number of factors like if and how it was handled, the holding temp during service, immunocompromised status, etc. real world studies on pizza specifically show fairly low bacterial growth on pizza that was prepared safely and not handled, but significantly more (although still pretty low) if the pizza was handled during serving (which is more realistic).
But I mean literally millions of people eat rare beef every day without issue so it’s about how much risk you’re willing to tolerate, ultimately
These recommendations pretty much always err on the side of caution to such a degree that a lot of people don't really respect them. Saying you should throw away pizza after it has been in room temp for 2 hours, come on now, when there's some actually serious recommendation peoole will think it's similar sort of nonsense and not follow it.
Rare beef is a bit of an anomaly in that the meat is quite dense, and while the surface can grow bacteria, the interior spolis much slower (not to say its safe forever, but can be safe eat cooked Pennsylvania rare, for example).
True but some people have rare burgers and the ground beef ruins what you’ve said
We had a rule where if you left pizza out for 24 hours, it's still good if you're willing to have diarrhea butt.
After 48 hours, it's still good if you're willing to vomit.
In college, definitely had people who took those risks.
There is a persistent belief that cooked rice is exempt from the 4-hour rule. That belief is mostly wrong, because the water activity in cooked rice is still able to support a few hardy species of bacteria, including b. cereus (the bacteria that cause this illness), in some circumstances. It's pretty rare, but possible, and therefore inevitable that it will eventually happen to people who fail to refrigerate rice.
