Have you seen this defect? In recent contact with the Cornell University Plant Disease Diagnostic Clinic, they said, “Without testing, it is not a conclusive diagnosis, but we have seen similar sunken lesions on celery infected with Cucumber Mosaic Virus. ” I appreciate their opinion, with only having a picture to look at, it is impossible to be 100% certain.

Celery- Mosaic Virus
Broccoli-Yellowing
We have all seen the yellow and discolored bud clusters that occur on broccoli. Unfortunately there are no real scoring guidelines, to determine how much is allowed before the discoloration is scored as a defect. The USDA has recently published (November 2008) a revised inspection instruction handbook for broccoli, but the instructions fail to address the […]
Peppers- Defect No Longer
Take a look at the following peppers. Can you identify the defect from this picture? If you had said the pepper with the turning red color was the defect….I would have agreed with you. But, something changed. Sometime within the last few months “turning red color” (or full red color) on green hot peppers is no longer being […]
Modified Atmosphere Packaging
Recently we have started to see more and more use of modified atmosphere packaging for different fruits and vegetables. The breathable packaging is designed to create the optimal shelf life conditions. This is done by proprietary engineering of the package’s polymer so that the correct balance between oxygen and carbon dioxide is maintained while excess moisture […]
Potatoes- Ingrown Sprouts
Ingrown or Internal sprouts on potatoes are a defect when a potato begins to sprout, but the sprout grows into the flesh potato instead of growing outward. I have only seen this a few times over my career as an inspector, but I have never seen this severe enough to score as a defect. This defect is to be scored as an internal […]
Limes-Yellowing/Blanching
Do you know the difference between what is scored as Yellowing and what is scored as Blanching? Yellowing (#1) is due to age, and is scored as a defect when the yellow color is plainly visible. In other words, whenever you see any amount of yellow color, the lime is scored against the (5%) tolerance for serious damage. Blanching […]
Peaches-Internal Discoloration
A question was submitted asking about the cause of internal browning or discoloration of peaches. From my experience, the internal discoloration that sometimes occurs in peaches is due to chilling damage. But what is unique with peaches, the chilling injury develops at warmer than expected temperatures. Peaches should be stored between 30 and 35 degrees, but […]

Broccoli-Florets Discoloration
Broccoli florets (and crowns) are covered under the U.S. Grade Standards for Broccoli. A blogger sent in these pictures and was interested in everyone’s comments. Would the discoloration affecting the cut stems be a defect? There is no definite mention of this in the grade standard, only the general definition of damage, “materially detracts from the appearance, or the […]
Oranges- Ethylene Gas
Has anyone had any experience with storing oranges along with products that produce ethylene gas? A reader has noticed that once they changed their storage of oranges, with other ethylene producing commodites, the oranges have showed an increase in decay. Is there a corrolation between the two? Your comments would be appreciated.
