This is shocking and unexpected. That sucks so hard, as I have just finished printing the tower. But I am very thankful, because without you, I would have probably ingested unhealthy chemicals. Thank you very much.

I will choose a PETG brand with a food safety certificate and avoid Creality PETG.

Edit: I also just learned that the hotend nozzle needs to be switched out, too. Brass contains lead, which is very unhealthy. Switching it out with Stainless Steel.
