Rotten Food is a resource harvested from larger food nodes found across the yard and in mass in the Trash Heap biome. Along with this, it can be obtained when meals spoil. If eaten, it gives the Sick effect that drains 7.5 health every 3 seconds for 15 seconds for a total of 37.5 health.
The food has limited use, but can be used in the Garden Patch as a fertilizer to increase the "Green Thumb" effect.
It can also be obtained as a rare drop from Meaty Gnats.
