Can green tomatoes be eaten once they turn red, and are they toxic?

Ripe red tomatoes that were originally green are generally safe to eat and not toxic; however, moderate consumption is recommended. If the tomatoes show signs of spoilage or have an unusual odor, they may be toxic and should not be consumed. Green tomatoes that turn red upon ripening are usually edible. When tomatoes are still green, they contain a higher amount of chlorophyll. As they mature, the chlorophyll gradually breaks down, causing the color to change from green to red.
