If a hot slice of pizza was placed uncovered into a fridge with covered meat is there any issue with the meat or anything else? I am assuming its fine since we bedieved can for sure rely on the fact that many poskim consider pizza a “dry” food that doesn’t produce zeya. Am I correct?
Yes, you are correct, there is no issue with placing uncovered pizza an uncovered meat in the same fridge. The reason however is simpler than what you are writing, because the fridge is cold and there is no zeah in a fridge. Zeah is only when the hot steam of the meat mixes with the other foods, but in a fridge there is no hot steam, so it isn’t an issue.
