1. Today there is a lot of awareness about insect infestation in all types of foods. People know a lot of the facts on the topic from kashrus agencies, shiurim with presentations, and the like, leading to a major improvement in taking care to avoid the issur of insects. Also, today one can get many fruits and vegetables grown specially to greatly minimize infestation. Thus, it is easy to stay away from potential concerns for the issur of insects.
2. On the other hand, though, there are still many types of produce and crops that cannot be checked properly, and there are still many people who are not properly aware of the severity of the issur. They are not careful and eat these foods without checking, violating the issur of eating insects. Thus, we saw a need to write a series of issues to inspire improvement in this serious issur. First we will introduce the issurim of insects; then we will discuss what one needs to do practically to avoid the issur.
3. Teaching publicly. Even if one is personally careful about the issur of insects, it is vital to caution others in Klal Yisroel about the seriousness of this matter. Yidden are holy and want to guard themselves and avoid issurim, but people make mistakes due to lack of knowledge. One who warns others will shine brilliantly and bring zechus to the tzibbur, thereby earning wonderful brachos (פ לא יועץ "בדיקה " י ,סו"ש העבודה שער ז פ''ד, פר''ח סוף סי' פד ).
