Source for not eating insects

The lives of the Jewish people are governed by our Holy Torah, the Talmud, and the Code of Jewish Law. In every aspect of life, from birth to death and after, from awakening in the morning until retiring at night, through both happy and sad times, we are guided and instructed by The Almighty.

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.

Hechsher on fresh produce

Most locally picked unprocessed fresh produce such as raw fruits, vegetables and nuts are technically kosher, but need to be checked for various issues.

In most instances, even produce that bears a reliable Hechsher requires checking. The exception is if the Hechsher states that no further checking is needed. The reason for this is that a Hechsher on a product generally only relates to aspects of kashrut other than infestation (e.g., no non-kosher flavours, colourings, etc. have been added to the product; the manufacturing process and equipment have been approved; etc.).

Moreover, in certain instances, infestation can develop after the manufacturing process.

Responsibility to check for insects

Insects are so small – does it really make a difference if we accidentally eat one? If a person eats a water creature (e.g., a worm found in fish), he transgresses 4 prohibitions. If he eats a land creature (e.g., a crawling insect), he transgresses 5 prohibitions. If he eats a flying creature (e.g., a flying insect), he transgresses 6 prohibitions (see Gemorah Makkos 16b).

On the other hand, taking care not to consume such creatures elevates us spiritually, and for this reason alone we were worthy of having been taken out of Egypt. (See Rashi on Vayikra 11:45).

Accordingly, checking and cleaning produce is very important and requires tremendous diligence.

This places an enormous responsibility on us as kosher consumers and an even greater responsibility on a mashgiach.

Even creatures that are so small that only a searching eye can detect are prohibited. Moreover, if the reason they are not seen is not that they are too small, but that they are too difficult to find, they are likewise forbidden, as a concealed creature is still a creature. However, anything that is microscopic is of no concern. There is therefore no obligation to use a magnifying glass to check. However, if you do see something and you cannot identify whether it is a creature or merely dirt, then you must use a magnifying glass to help you make a determination (10 x magnification is best).

Ongoing research

The Beth Din is constantly researching infestation issues and methods of avoiding infestation.

For this reason, the methods in this manual may differ from the instructions that have been previously published. At this point in time, the processes mentioned in each case are the only acceptable methods for Food Services. Before using a method not listed in this guide, a Food Service requires written permission from the Beth Din

Who may check fruit and vegetables?

Any adult Jew may check fruit and vegetables, provided they:

• are Shomer Mitzvot.
• know what to look for.
• know how to check.
• have good enough eyesight.

In Kosher SA licensed Food Services, only a Kosher SA qualified Mashgiach may check vegetables.

Halacha states that a non-Jew may never be relied upon to check for infestation even if he is extremely knowledgeable and very dependable.

However, a non-Jew may assist in the cleaning of fruits and vegetables under careful and constant supervision. This will be discussed further below.

To check produce, you will often need proper equipment

General challenges with checking vegetables

Checking for insects properly is a very time consuming and tiring procedure that requires a great deal of patience, diligence and Yirat Shamayim (Fear of Heaven).

• Insects are often very small.
• Insects are often mistaken for dirt.
• Many insects have a similar colour to their host vegetable.
• Many insects hide between crevices.
• In some cases, leaf miner occur in leafy vegetables and can only be noticed by a trail of tunnels.

Insects’ appearances

Aphid

• Aphids are small sap-sucking insects.
• Common names include greenfly and blackfly.

Leaf Miner

This is a tiny black and yellow fly that attacks many different vegetables. The fly lays eggs into the leaves and larvae make tunnels inside the leaf as they feed. (See the tunnelling section under vegetable checking methods).

Thrips

These flying insects are slender and extremely small (between 0.5 and 2.5 mm long).

THE LIFE CYCLE OF INSECTS

Every stage is forbidden to eat (if big enough to see)

General stages of fruit and vegetable checking

Depending on the type of infestation, as well as the type of produce involved,  there are different ways of preparing insect-free food. Sometimes careful cleaning is sufficient. Sometimes all that is required is a test. And in some cases, a visual check is adequate.

Let us discuss each of these in general terms to give us a broad picture. The applications of these processes will then be spelled out in each individual case.

CLEANING

Where the infestation is easy to wash off, we simply clean the produce. Examples of this are rinsing of peppers and brushing down of celery sticks.

Sometimes detergent is the only way to wash off the infestation. An example of this is cabbage. This is because the insect that often infests cabbage is called a thrip. This tiny insect grips onto the leaf and cannot be washed off. But after soaking the leaves for a few minutes in very soapy water, the leaves become slippery, and the thrips lose their grip.

This system, however, is not effective for all insects. Aphids (greenfly) grip leaves with their elongated mouths, so they will not wash off in soapy water.

However, you can wipe them off by sponging both sides of a leaf using a soft, very soapy, sponge. Accordingly, this method is suitable for lettuce.

Strong agitation in soapy water can remove these insects, but testing is required to see if all insects have been removed (as in the micro-cloth method)

Very Important: Cleaning (as opposed to checking or testing) may be done by a non-Jew under your careful and constant supervision. But you need to be aware, that you can only allow the non-Jewish staff member to help you if you are standing over them watching them clean the produce correctly. If you have left the room, they may not continue. You need to ensure the method is followed through 100% accurately. Be aware that if 1 insect is left behind by the staff, you are ultimately responsible.

CHECKING

Where it is possible to visually detect all infestation, we very carefully check the produce visually with the aid of strong lighting. Examples of this are lettuce and butter beans.

Where aphids are the problem, you must soak the leaves in a soap-water solution, before doing a visual check. This irritates the aphids and often causes them to release their grip from the leaves.

TESTING

Sometimes we perform tests that allow us to determine the level of infestation in a product. (Such as shaking the produce over a surface and scanning that surface for infestation; or passing water that the produce was soaked in through a fine cloth and examining the cloth).

If this reveals infestation, further cleaning will be necessary, or we do not use the produce at all. This technique is used where the shape of the produce makes it impossible to visually detect infestation. Examples of this are: flat leaf parsley and some other fresh herbs.

Produce not permitted at food services

If it is impossible or impractical to check produce properly, then such items may not be used in commercial food preparations. Examples include: corn on the cob, regular spinach, broccoli florets and certain berries.

Fresh produce that doesn’t need checking

Not all produce requires checking for infestation. Anything classified as “rarely infested” may be eaten without checking. Some examples include: apples, bananas, potatoes, carrots, and beetroot.

Also included in this list are industrially dried chopped/flaked herbs with a hechsher.

This may sound surprising, as many of these herbs may not be used at all in their fresh state due to extremely high levels of infestation. The intensive and numerous procedures involved in the drying of these herbs, however, will actually eradicate any infestation. Nevertheless, storing dried herbs for extended periods can occasionally result in infestation (which you will notice easily with a superficial inspection).

Sponging method

Note: This method can only be used where the leaves are large enough to sponge on both sides.

EQUIPMENT: SOFT VERY SOAPY SPONGE

1.Ensure that any leaves that are too small to be sponged on both sides are discarded. If there are, remove the flowers from the top of each branch.

2.Separate leaves so that the entirety of each leaf can be sponged.

3.For produce prone to tunnelling*, visually check 10% of the leaves. If you find any tunnelling, visually check it all. Remove any leaves with tunnelling. Only the tunnel-free leaves may be cleaned/ checked using this method.

4.Rub both sides of each large leaf with a soft, very soapy, sponge. Take care to wipe into all folds. Discard any parts which you cannot reach with the sponge.

5.Rinse the soap off the leaves under a stream of cold water.

6.You do not need to visually check the leaves once this method has been used.

The micro-cloth vegetable cleaning method

Potentially infested produce is cleaned with soap and water to remove insects. The efficacy of the cleaning process is assessed by checking the cleaning-water for insects. The cleaning-water is checked by filtering it through a specialised cloth and inspecting the cloth. If no insects are found on the cloth, we can assume the produce is clean.

For food services, a trained staff member can clean the produce and can be supervised by the mashgiach, but any checking must be done by a SA certified mashgiach.

Necessary Equipment:

• Clean Running Water
• Bowl or Basin
• Micro Cloth
• 2 Strainers (Colanders)
• Light box
• Food Safe Slippery Vegetable Wash

Additional Recommended Equipment:

• A Spray Bottle (to disperse suds on the cloth)
• Toothpick (to move around dirt on cloth to better inspect for insects)
• Magnifying glass (for those unfamiliar with insect identification)
• Multiple Bowls/Basins (to speed up the process)

Preparation Steps:

Separate all leaves if applicable. For produce prone to tunnelling, visually check 10% of the leaves. If you find any tunnelling, visually check it all. Any leaf with tunnelling needs to be removed, together with the stalk it is attached to. Only the tunnel-free leaves may be cleaned/checked using this method. This needs to be done for: baby spinach; basil; coriander; curry; kale; mint; parsley; rocket; sage and savoury.

While not required, it is recommended to pre-wash produce before using this method. This helps minimise the remaining dirt and insects to be cleaned.

The basin should be prepared with a solution of water and veg soap. There should be enough soap so that the water feels slippery. There should be enough liquid to cover the produce.

Place the Micro Cloth in between two equal size strainers (colanders).

Place the separated leaves into the soapy solution for 1 – 2 minutes. If the produce does not feel slightly slippery, add more soap. Agitate the produce thoroughly in the water solution.

Remove the produce from the water, allowing the excess water and soap to drain back into the bowl or basin.

Discard the water afterwards.

Repeat step 3 & 5. Once produce is believed to be clean or a er the second wash, ensure this wash is done in a basin or bowl where the water can be used for checking.

Remove the produce from the water, allowing the excess water and soap to drain back into the bowl.

Pour the water through a MicroCloth that is sandwiched between 2 strainers. Run water through the strainers (and Micro-Cloth) to remove any remaining suds.

Preparation and Cleaning could be done by a trained staff member, but any checking must be done by an adult Jew who knows what to look for and has good enough eyesight. In BD licensed food services, only a BD qualified Mashgiach may check.

Checking Steps:

Carefully remove the Micro-Cloth from between the strainers/ colanders and place it on the light box.

Carefully inspect the cloth for insects. A spray bottle and toothpick are recommended to dissipate remaining suds and move around dirt. – If insects are found: repeat the process. – If insects found after 3 repetitions of the process, do not use the produce. Use less infested produce instead. – If no insects are found – the product may be rinsed of any remaining soap and used

Label and store the clean product in an insect-free environment to prevent re-infestation
