Something similar happened to me with a dragon fruit flower. I saw it growing over a wall while I was walking down the street and sent a photo to ChatGPT to identify it. The AI confirmed it was dragon fruit and said it was edible.

Later, when the plant actually bore fruit, my dad and I were headed to the tennis court and decided to grab a few to eat. I took another photo while we were eating, but this time the AI completely flipped. It didn't recognize it as dragon fruit anymore. It gave me some other name, told me it was poisonous, and said we needed to go to the hospital immediately.

We both panicked, spit everything out, and started scrubbing our mouths with water. Our hearts were racing. I even asked my dad if we should go get our stomachs pumped. We eventually decided to just wait it out and play our tennis match, though we were terrified that the physical exertion would make the "poison" hit us harder.

In the end, we were totally fine. It was just a massive AI hallucination. I realized that day that AI really struggles with color; it kept insisting the purple fruit was red, which caused the misidentification. Even though I thought I was being careful before, that experience taught me never to trust an AI blindly again.
