Fruit & Veg Checking
The Torah (Vayikra 11:20-23) states that insects and crawling creatures are not Kosher. Consequently, many vegetables, fruit and other products that are prone to infestation, must be checked and the insects removed. The method of checking and removing insects from vegetables, fruit and other products differ according to each species as will be detailed below. Most locally picked unprocessed fresh produce such as raw fruits, vegetables and nuts are technically kosher, but need to be checked for various issues.
General stages of vegetable checking
Cleaning
Where the infestation is easy to wash off, we simply clean the produce.
Checking
Where it is possible to visually detect all infestation, we very carefully check the produce visually with the aid of strong lighting.
Testing
Sometimes we do not examine the produce at all. Instead, we shake the produce over a surface and scan that surface for infestation.
