Summary of the controversy over tiny insects: According to the rules of halakha one should act leniently, but because of modern technology heightening our awareness of tiny insects, and providing options for identifying and exterminating them, there is room for the stringent opinion as well * The middle approach: Do the normal actions required to remove insects, but not in a manner that causes considerable inconvenience or expense * In large factories and kitchens sometimes stringent procedures should be set in order to maintain basic kashrut * The practical halakha – what to do according to each opinion in regards to leafy vegetables, cauliflower and broccoli, corn, strawberries, green onions and leeks
The Controversy over Tiny Insects
In the previous column, I briefly summarized the dispute over whether to check for tiny shratzim (insects) that an ordinary person is unable to see while looking at the vegetable or fruit. I wrote that the halakha goes according to the lenient opinion since this is a dispute regarding a rabbinical prohibition, for from the Torah, these insects are batel b’shishim (less than 1/60th of the total volume of the food), and even from Divrei Chachamim (rabbinic status), some poskim are of the opinion that they are batel in close to a thousand. There is also a safek(doubt) whether even according to Divrei Chachamim, it is necessary to check for them according to the rules of “miut ha’matzuy” (a substantial minority). In addition, there can be no Torah prohibition regarding a tiny thing whose taste and ingestion goes undiscerned, especially if it undesirable, and thus considered d’var sh’aino mitkaven(something unintentional) and there is no prohibition.
The Stringent Opinion is based on Modern Developments
It should be added, however, that the opinion of the machmirim(stringent poskim) has room today as well, as it is based on modern methods of research and measurement, which have heightened our awareness of the presence of tiny vermin in vegetables and foods. It can be implemented thanks to the advances in science and technology that have provided tools for dealing with tiny vermin, such as the development of detergents from which types of soaps have been produced, whose widespread use began about a hundred years ago, and can now be used to clean vegetables from tiny shratzim. Also, the development of refrigerators in which vegetables and food can be stored without the growth of tiny shratzim. In addition, methods have been developed where most vegetables and fruits can be grown under conditions that do not breed tiny insects. As a result, many rabbis in recent generations have instructed le’hadare (to enhance the mitzvah) according to the method of the machmirim poskim.
