Strawberries- Brown Discoloration

Every now and then you may see some golden brown to dark brown discoloration affecting strawberries.  You have to remember strawberries are harvested and packed right in the strawberry fields, with the picker also quickly verifying the quality of the berry before placing it in the clamshell. Although the strawberries are grown on plastic they […]

Potatoes- Black Dot

During my 35 plus years involved in the inspection of fresh fruit and vegetables I never came across Black Dot on potatoes.  Not one potato shipper or receiver ever complained or mentioned Black Dot to me.  But during the past two years, the USDA has made it a point to include Black Dot as a […]

Tomatoes-Moldy Stems

Last week, while in a training class, we came upon some tomatoes showing moldy clayxes and stems.  Of course the question came up about the scoring guideline, for moldy stems on tomatoes and on cluster tomatoes. The class and I thought it may go a few ways, for instance: Score the defect as serious damage, […]

Growth Cracks/Scars

In many of these past posts I have referenced the defect “growth cracks” quite a few times.  There may be few of you that are not really clear on what a growth crack is, or how it is different from a scar.  To begin with, both scars and growth cracks are considered to be quality […]

Eggplant- Internal Discoloration

Every now and then I disagree with a specific USDA sampling procedure, especially when it involves cutting (destroying) produce.  When it comes to eggplant, the USDA seems to go overboard with their cutting procedure instructions.  Their own inspection instructions state: Sampling for Internal Defects When inspecting eggplant for internal defects, randomly select and cut, a minimum of […]

Pineapples- Gummosis

Every now and then you may come across some problems with pineapples in a shipment.  Common defects are bruising and decay, which are easily identified.  Recently an inspector came across some pineapples that were showing a brown discoloration around the eyes.  It was correctly identified as gummosis.  He shared with me the following images. As shown […]

Onions- Sunburn

Although you may come across some onions with a green color, caused by sunburn, the scoring guidelines will most likely prevent you from scoring sunburn as a defect. We will discuss northern grown onions (onions grown in Idaho, Oregon Northern California, New York, etc) as the scoring guideline for Bermuda Granex Grao type onions is […]

Carrots- Air Cracks

You will sometimes come across carrots that show definitive cracks running the length of the carrot. Many inspectors confuse this defect with bruising or mechanical damage, or may think these are growth cracks.  But no, these are not caused by rough harvesting or due to sudden growth while in the ground.  This defect is called “air […]

Romaine- Peeling and Feathering

With the recent cold weather you may have noticed some peeling and feathering affecting the outer leaves of romaine.  This defect is the by-product of romaine being affected by cold (below freezing temperatures) in the fields, while growing.  The water in the cell walls of the outer epidermis of the leaves freezes, and when ice crystals […]
