Is it safe to eat growing rhubarb that has been subjected to frost or do you have to discard the current stalks?

It is generally safe to eat rhubarb stalks that have been subjected to frost, as long as they appear healthy and are not mushy or damaged. Frost may cause some discoloration or softening, but if the stalks are firm and intact, they can be harvested and consumed. However, avoid eating any leaves, as they are toxic regardless of frost exposure. Always ensure proper preparation and cooking, as this can also help reduce any potential risks.
