Shulchan Aruch Yoreh Deah 298:1 אין אסור משום כלאים, אלא צמר רחלים ואילים עם פשתן. אבל צמר גמלים וצמר ארנבים ונוצה של עזים וכל שאר מינים, מותרים בפשתן. The only thing forbidden because of Shaatnez is sheep and ram wool with linen; camel wool, rabbit wool, goat hair, or other similar items are permitted with linen. The rule that only sheep and ram wool ...

Per Shatnez Testers of America and Chabad.org no. When we speak of wool, we are only referring to wool obtained from sheep or lambs. Other materials, such as camel's hair, mohair, angora, cashmere or alpaca wool, present no shatnez problems.

HaRav Yitzhaq Yosef in his Qitzur Shulhhan Arukh, Yalqut Yosef (Orahh Hayim 27:4) states (my translation/emphasis): מותר להסתכל בראי כדי לראות אם התפילין של ראש מונחין במקומן. ומכל מקום אין צריך להקפיד בזה כל כך, ודי שיבדוק כפי מה שיש ביכולתו שהתפילין יהיו מונחין במקומן, שלא יטה לצדדין. וכן צריך שיהיה הקשר של התפילין (של ראש) באמצע. It is permitted to look ...

According to the current (updated February 7, 2014) version of the Star-K's "Insect Checking Quick Reference Guide for Mashgichim", corn doesn't need to be checked for infestation. It does say that the corn should be stored sealed and in a cool, dry area to prevent infestation. [And, of course, if the corn is obviously infested, don't eat it.] It doesn't ...

First of all raw eggs do not need a hechsher according to CRC, Denver Vaad HaKashrut and others. The presence of a hechsher on the box does not appear to be a factor in two major treatments of the topic. In a discussion on blood in eggs, the OU explains that, due to modern production methods, any blood spot found in eggs will never develop into an embryo ...

You should CYLOR for a final ruling, but it seems (Shach and Taz to YD 84:13, Chochmat Adam 52:9, see also Rama OC 553:3 (however see Shu"t R Akiva Eiger 76)) there should be no problem blending the fruit as the intention is to prepare the food not to nullify the insects. Once the insects are cut up, they are nullified in the mixture (YD 101:6). ...

This depends on the Hashgacha. Some Hashgachot on broccoli are only signing off on the purposefully present ingredients and processing equipment, but are not addressing the requirement for Bedika (Triangle-K for example on a lot of frozen produce (See here)). Others are signing off that they indeed already performed a Bedika (typically via Chazaka) and ...

I heard R. Nota Greenblatt say that using a tefillin mirror is a way of announcing that you are an ignoramus.

Rav Binyomin Zilber (Oz Nidberu) saw me using the mirror in yeshiva for this purpose and called me over to chastise me. He insisted that using one's fingers was sufficient and it was better not to use a mirror.

Computers are used quite effectively for checking for errors in STa"M. Your understanding of how it works is basically correct. The scanned text is compared with a standard which is known to be kosher. The program would have a variety of "standard" versions for different writing styles and column formats. To correct for differences in handwriting, a ...

According to Rabbi Moshe Vaye popcorn kernels should be checked. A. Strain, over a white surface, in a strainer with large holes and check whether any small insects are found among the debris that fell through. B. Spread out a handful of kernels at a time on the palm of your hand, and look for insects among the kernels or round holes in the kernels. Turn ...

As Rav Herchel Schachter notes at approximately the 26:30 mark in this shiur, Rav Shlomo Zalman Aurbach clarified the halacha of checking twice every seven years, that it is not the case nowadays. The twice-in-seven-years requirement was stated when the situation was heat extremes. But nowadays, where we have air conditioning in the summer and steam in the ...

Nitei Gavriel Hilchos Nesuin Volume 2 Chapter 61 mentions this Minhag in the name of the Shela.

The Aruch HaShulchan (291:1) says that in a place which is exposed to the elements and moisture or rot are common, one should check more often than twice in seven years and at least once a year. He notes that this was his personal practice.

FWIW, in Eretz Yisroel, there are vacuum packed bags of grains under Badatz supervision. They tend to be slightly more expensive but are "נקי מחשש תולעים". I saw some in stores near the Mir (in the Beit Yisrael neighborhood of Jerusalem), and would guess they're widely available in chareidi neighborhoods. If your concern is to prevent bugs being born in ...

Although the other answers mentioned that cashmere may be mixed with linen as it comes from the Kashmir goat, practically this is not true. That is because cashmere by itself is a very expensive material. Each goat can only produce about 4 ounces of fibers a year and it is estimated that fleece from 4 to 6 animals would be needed for a sweater. Because of ...

See this list of "dried spices that are acceptable for kosher use without specific Kosher supervision" - Allspice is literally the first entry. Many spices are considered to not require supervision when by themselves. Blends require either supervision or a thorough spec sheet to ensure that the blend only contains spices (some blends use flavorants, sugars, ...

There is an organization in Lakewood New Jersey that gives a week-long training every once in a while.

According to the CRC "Mushrooms – Fresh mushrooms must be rinsed and a cursory inspection is needed. Portabella mushrooms should have the brown under part removed. All dried and frozen without any added kosher sensitive ingredients are acceptable. Canned or jarred mushrooms must have a reliable hashgacha." Source: http://www.crcweb.org/fruit%20&%20veg%...

The way to go is to cut the shroom into slices (including the stem) and to check if they have needle-size brown tunnels. Also good to know - there is no need to peel the shroom.

The OU kashrus site writes https://www.ou.org/torah/halacha/hashoneh-halachos/sat_08_25_12/ "46:43 Small worms are sometimes found in fish, in the brain, the liver, the intestines, the mouth and the gills. This is common in such fish as pike and herring. When this is common, one must check for them. Small insects can also be found on the outside of a fish, ...

The rebbetzins/kosher kitchens you have observed are probably doing full checks rather than "sample" checks because full checks are often required for leafy vegetables. Vegetables which are buggy a majority of the time, or even a significant minority of the time, must be thoroughly checked. Even checking a majority of the vegetable in question is ...

The Shulchan Arukh's stipulation that only insects visible to the naked eye are prohibited (84:36) carries the suggestion that checking foods visually is halachically necessary. This document brings several sources that the checking process itself ("bedikas hamazon" or "bedikas toalim") is indeed halachically required: What frequency level of ...

The word "tekheiles" actually refers to a kind of blue wool; not the dye itself, but the dyed wool. Most hold that tekheiles must come from the chilazon. There is the opinion of the Tif'eres Yisrael (stated in his introduction to Seder Mo'eid, kelalei Bigdei Qodesh "hinei") that tekheiles is any colorfast blue wool of the right hue. According to him, the ...

In sefer v'yismah Moshe,Rav Elyashiv was asked this question and he said a mirror is mutar for teffilin since the idea of a mirror has changed and is not considered a tachsit of women nowadays .

Mishnah Parah 2:5 היו בה שתי שערות לבנות או שחורות, בתוך גומה אחת, או בתוך שתי כוסות והן מוכיחות זו על זו--פסולה. If it has 2 white or black hairs within one "depression," or within two "cups" in such a way that they clearly go together, it is invalid. The Mishna goes on to discuss other details, such as if the roots are red. Among ...

From the Kashrus Organizations, it sounds like it depends on what product the Mashgiach is being יוצא ונכנס for. At least for the milking process, the time frame for the Mashgiach's entering/leaving given by the OU is "In general, Poskim have ruled that yotzei v’nichnas supervision requires the mashgiach be present at the beginning of the milking, come ...

I would venture the following: It's unnecessary to mandate checking Arba Minim. Why do we need to check our tzitzis? Casually glancing at your tzitzis will not reveal their Kosher status - there's no visible difference between 6 and 8 strings to the casual observer. Tzitzis are worn all day - and are mostly out of sight. When they become pasul you wouldn'...
