How long before food spoils

I gave it 30 seconds in the microwave

Pippa I couldn't help it. I worried myself into feeling sick. I feel a bit unsettled in my stomach and I can't sleep. I don't know if it's from the worry or from the food I ate. It was fried rice and pot roasted chicken cooked at 8:00 am and eaten and 6:30 pm. Sitting out at room temperature 10 and a half hours.

I would try and think about something else since you have worried yourself into feeling sick.   Try to concentrate on a hobby or try light exercise to take your mind off your stomach. Even if you have eaten bad food, still try not to worry about it. these things happen to people from time to time. My dad  tasted a sip of bad milk.  The flavour was disgusting and it made him wretch.  He took a sip of water and it made him feel better and he forgot about it.

Simply relax! 

The slightly unsettled feeling turned into a full blown nausea that had me certain I was going to throw up but I didn't. I eventually fell asleep. Just woke up and feel like I'll need to use the washroom. Maybe I just need to pass out some toxins and I'll be fine. Or maybe anxiety made me nauseous. I have eaten food that's been out 6 hours, even 8 or 9 hours and no reaction. I think this time I just worried about it too much. I literally worried from the time I ate it and for the entire rest of the night. Now I feel kind of paranoid and don't want to eat anything at all but that'll make me more sick so I'll try some crackers or banana. How long did your sickness last when you ate the bad rice?

Once I vomited, I felt better very quickly.  It sounds like your anxiety has given you a bad stomach since you have had no reaction to the rice. I would forget about it and eat normally as if nothing has happened.   The more you reduce food, the more you will be frightened to eat properly and the longer you will feel unsettled. Once again, relax!

Well, it's been well over 24 hours and no reaction other than the nausea this morning. I did not vomit or even have a bowel movement. I'd like to think I'm in the clear. I ate a normal meal at lunch time and felt fine after. What worried me is the fact that I'm on a PPI which will reduce acid production in my stomach. As you know, an acidic environment is needed to kill bacteria ingested through food. I was fearful that if my acid content was too low, the bacteria would be able to survive and have harmful effects. Is it true that a person becomes more susceptible to bacteria if they're on a PPI, because of the reduction in acid? 

If you have had no reaction to the rice in 24 hours, I would simply forget about it and relax!  It is more likely your anxiety had brought on your stomach upset.  

PPIs can make you more susceptible to stomach flu,.  Since you are worrying about this, it may be better to come off the PPis slowly and switch to H2 blockers instead.  This may help to reduce some of your anxieties.

In the meantime, the most imporant thing for you to do is to relax and enjoy life!   Remember, the rice did not affect you!   I have.acid reflux and IBS and I do not wory about either of these conditions.  I took omeprazole when my reflux was diagnosed, but I didn’t worry about taking it.   I eventually switched to H2 blockers because I couldn’t be bothered going back and forth to my doctor for prescriptions. Doctors increase my anxiety, so I avoid them if I can. 

I have come off the PPI and started a H2 Blocker called Cimetidine also known as Tagamet. 

My brother was on them for acid reflux and they worked.

It was cooked and left sitting at room temperature for 10 hours. It didn't have a smell but you can't always detect bacteria by smell or taste. I've learned my lesson and will definitely refrigerate food soon after or not eat it. I have eaten food that's been out for 8 hours and no reaction. This time I think I worried and obsessed over it too much which may have caused me to feel unsettled in my stomach.
