How to clean:

Fresh Blueberries:

1)     Prepare Checking Station - Add cold water and sufficient amount of food-grade soap or vegetable wash that contains a surfactant in the ingredients (for example FIT, Monster or Nature Clean) to a clean sink or container. The appropriate water to produce ratio is 3:1 (3 parts water to 1 part blueberries). The proper amount of vegetable wash/soap is when the soap suds are visible in the water.

2)     Soaking & Agitating - Place Fresh Blueberries in water ensuring that they are completely submerged under water. Blueberries are then thoroughly but gently agitated. Blueberries should be agitated in the water for a minimum of 1 minute.

3)     Rinsing – Remove blueberries from water and place a small handful into a colander and rinse under a strong stream of water (strong water pressure from the tap or spray hose is critical in ensuring the effectiveness of the rinse); rub through the blueberries gently while rinsing.

4)     Kosher Screen Method Guideline – At this time, we are not requiring a Kosher Screen for blueberries if the Mashgiach does the washing as described above. If the mashgiach does not perform the washing, then the mashgiach must perform the Kosher Screen Method on the blueberries to ensure that no infestation remains.

5)     Container – Fill up the container with fresh water. Place blueberries inside the container. The appropriate water to produce ratio is 3:1 (3 parts water to 1 part produce). Agitate well and slowly. Remove blueberries from the container, while shaking out the water from the strawberries; then place them in a clean container. Repeat until the process has been done to all the blueberries.

6)     Kosher Screen – Place a clean Kosher Screen in between 2 colanders and empty the water through the colanders ensuring that all the water goes into the Kosher Screen. Rinse the container with fresh water and empty the fresh water through the colanders. Let the water flow out completely through the Kosher Screen and into the drain. Shake the top strainer onto the Kosher Screen to ensure that any caught insects are now on the Kosher Screen.

7)     Kosher Screen Checking – Place the Kosher Screen on the light box. Use a spray bottle to gently spray water on the Kosher Screen. This allows the dirt to spread on the Kosher Screen and allows clearer visibility. Examine the Kosher Screen on the light box for the presence of insects.

  • If 1 or 2 thrips or mites are found then repeat steps 5-7 and re-check*.
  • If 3 or more thrips or mites are found then it has been demonstrated that washing was not performed properly and steps 1-7 must be repeated.
  • If an aphid is found then steps 1-7 must be repeated.
  • Produce may not be used if the Kosher Screen Method has been performed twice and insects are still found on the Kosher Screen.

*If the washing was not performed in the presence of a Mashgiach then steps 1-7 must be repeated.
