Pumpkins- Dirty
When receiving Pumpkins you should remember they are bought based upon grade standards, with U.S. No. 1 Grade being the most common grade.

Red Leaf Lettuce- Light color
A good question was sent to me regarding a lot of red leaf lettuce that arrived at their doors. Is there a minimum “red” color requirement for red leaf lettuce? As you can see the red color is not very prominent, only extending an inch or two from the margins. My first reaction would be […]
Strawberries- Hollow Center
I have recently received a few questions regarding the presence of hollow cores, or centers of strawberries. This defect is caused by rapid growth, due to fertilizer or heavy rains combined with heat, causing the strawberry to grow faster on the outside than the inside. This condition is found in other fruits and vegetables, most […]
