If you accidentally melt a plastic cutting board in the oven while baking cookies are still safe to eat?

It is generally not advisable to consume food that has come into contact with melted plastic. When plastic is heated, it can release harmful chemicals into the food, which can pose health risks.

The type of plastic and the temperature it reaches can affect the severity of the risk. Some plastics may release more toxic chemicals than others, and higher temperatures can increase the amount of chemicals that are released. Additionally, the length of time that the food is in contact with the melted plastic can also impact the level of contamination.

If you are unsure whether your cookies are safe to eat, it is best to err on the side of caution and discard them.
