Botulism question. Can I heat this jar with dehydrated tomatoes, roasted garlic, rosemary and olive oil in a pressure cooker to kill possible spores? More details in comment. Help?

I shared this in the tomatoes subreddit and someone pointed out I should throw this away because of possible botulism. I kept dry tomatoes and raw garlic in oil last year and nothing happened. This year I wanted to eat the garlic so I roasted it. My question is: Can I put this jar in a pressure cooker to kill botulism spores, and if so, for how long? My tomatoes and the oil are absolutely delicious btw.
Here’s what I put in the jar: Two heads of garlic were roasted. First was roasted at 180 Fahrenheit for at least 2 hours and the other one for 8 hrs. The tomatoes were dehydrated in the same oven for 8hrs. The rosemary sprigs were added to the oven for the last half hour.

No, you cannot.

I am not an expert. This is not medical advice. I’m sitting beside my lovely yet brash soon to be wife who is a physician who I just showed this post to. “Tell him to turn off the screen saver function on his phone. Hit 911… and in a while he can hit send quicker”
Throw….that……out.

If you ate this, knowing the risks, and got botulism, would you be okay with that? Or would you rather go on to enjoy many more meals to come by instead tossing what you’ve already warned to be risky? You wouldn’t be wasting it. You would be accepting the lesson people are trying to teach you by warning you away from the potential consequences of your creation. And by doing that, you could later re-create this in a safer way. Perhaps by keeping the dehydrated food and the oil separate until cooking time, or something else. But little would be lost.
In the end it is your decision, and while the people here are cautious, it’s for good reason.

If you heat it above boiling before eating for a minimum of 5 minutes, it would kill the toxin. That said, it’s not worth the risk.

I came here with an honest question and looking for information to help me decide. I will toss this jar.
I don’t get what I’ve said to make people think I am trying to convince myself that this is ok to eat.
I won’t, but jeez man… the downvotes, condescending comments and sarcastic responses to my questions are just uncalled for. Thanks for the info to those who took the time to actually write something helpful.

i guess i can’t find the background on this jar. stuff like dehydrated toms and garlic can stay good in oil in a fridge for a VERY long time. what’s going on? is there a story i’m missing? thx.
ETA – is the white stuff on the outside of the jar that’s being examined?

Any dehydrated veggies still have anywhere from 5 to 20% moisture in them. It is impossible to dehydrate to zero in home environment. Moisture + oil + time = mold spores grow. Botulism is anaerobic so it does not need air. Heating jar up kills percentage of spores, but not all of them. Even from 0.1% remaining, with time, colony regrow and will make you sick.
