How can certain foods pass straight through you when your intestines already have digesting food in them from previous meals blocking the path?

It takes ~36 hours from the moment you bite into your meal to when you’re pooping it out. Meaning, your digestive tract has 36 hours worth of meals it’s currently digesting at any given time.

When you eat something bad, it seems that you’re on the toilet pooping it out within the hour. How is that even possible if the pathway is blocked by 36 hours worth of meals?

The 36 hours is just the average amount of time food spends in the average person’s digestive system. Individual people may have a longer or shorter time, as evidenced by the number of people replying here who have found proof of passing things like corn (which we don’t digest the outside of the kernel so it still looks like corn on the way out) much faster than the average.
Also, after you eat, if your large intestine is full, your body tells it to get ready for more incoming food waste, so it empties what it has, no matter how long it’s been there.
