Question
I often see meat labeled as “Kosher,” “Glatt Kosher,” “Chalak,” and sometimes “Chalak Beis Yosef.” I always assumed they all mean the same thing, but different people tell me different things. Some say Glatt is an Ashkenazi standard, while Chalak Beis Yosef is a Sephardic standard. Others say all kosher meat today is Glatt anyway. What do these terms actually mean, and is there a practical difference between them?
Answer
The terms all relate primarily to the examination of an animal’s lungs after slaughter and its Kashrus status.
- Chalak and Glatt literally mean the same thing, namely “smooth.” “Chalak” is the Hebrew term while “Glatt” is the Yiddish term. Both terms fundamentally refer to an animal whose lungs are smooth and free of problematic adhesions (sirchos). The real question, however, is not what the words mean, but rather what each kashrus agency considers a problematic adhesion. This is where the practical differences begin.
- Chalak Beis Yosef ideally refers to meat that satisfies the stricter Sephardic standard of the Beis Yosef, requiring lungs that are genuinely smooth and free of adhesions, without relying on later leniencies that permit certain adhesions that can be easily torn. However, in practice, not every certification labeled “Chalak Beis Yosef” uses the exact same standard. Some certifying agencies have broadened the definition and include lungs with very minor adhesions that they do not consider significant. Thus, a product labeled “Chalak Beis Yosef” is not necessarily identical across all hashgachos. Under the supervision of Rav Moshe Yehuda Leib Landau obm, however, “Chalak” was reserved for meat that was literally smooth, with no lung adhesions or defects whatsoever. As Rav Landau quoted from his father, Rav Yaakov Landau, “Chalak is like the calf was born, without any re’usa at all.”
- Glatt Kosher ideally should mean the same thing as Chalak, since “Glatt” is simply the Yiddish translation of “Chalak.” In practice, however, many kashrus organizations, including the Landau Kashrus, use the designation “Kosher Glatt” for meat whose lungs contained only extremely minor adhesions that detached effortlessly and required no force whatsoever to remove. Rav Landau explains that these adhesions are sometimes viewed by many inspectors as little more than mucus-like attachments. Such meat is unquestionably permissible according to the accepted Ashkenazic custom of the Rama and can even be considered Mehadrin for Ashkenazim. Regarding Sephardim, whether such meat qualifies as true Chalak Beis Yosef is subject to debate. Rav Landau therefore intentionally distinguished between “Chalak” and “Kosher Glatt,” reserving the term “Chalak” for completely smooth lungs and the term “Kosher Glatt” for meat acceptable according to the Ashkenazic tradition of the Rama.
- Kosher meat which is not Chalak or Glatt refers to meat that was found kosher after the lungs were examined and processed in accordance with accepted Ashkenazic rulings. In these cases, adhesions may have existed that required actual mi’uch u’mishmush (rubbing, manipulation, peeling, or testing) to determine that they were not signs of a punctured lung. Such meat is fully kosher according to the longstanding Ashkenazic tradition recorded by the Rama and followed throughout Ashkenazi communities for centuries. However, it does not satisfy the standards of the Beis Yosef and is therefore not considered acceptable for Sephardim to eat.
Practically, the greatest distinction is between the stricter standard associated with the Beis Yosef and the more lenient Ashkenazic custom accepted by the Rama.
Explanation
What Is a Sircha? The entire discussion revolves around a condition known as a Sircha. A sircha is a pleural adhesion or attachment found on the lung made up of bands of fibrous tissue that abnormally connect the lung to the chest wall or diaphragm. Historically, such adhesions raised concern that there may have been a hole in the lung that rendered the animal a Treifah. Since lung adhesions are relatively common, the lungs of animals are routinely examined after slaughter. In fact, under ordinary circumstances, most parts of the animal do not need to be checked for Treifos, but the lungs do require examination because lung adhesions are common.
What Does “Chalak” Mean? The word Chalak is Hebrew for “smooth.” A truly Chalak animal has a smooth lung that contains no problematic adhesions whatsoever. Because there are no adhesions to investigate, the animal is considered kosher according to all opinions. Accordingly, the highest standard is a lung that is genuinely smooth from the outset.
The Dispute Between the Beis Yosef and the Rama: The major difference between Sephardic and Ashkenazic practice stems from a disagreement recorded in Shulchan Aruch. The Beis Yosef adopts a stricter approach regarding various forms of lung adhesions and is reluctant to rely on procedures that test whether an adhesion is genuine, and hence if an adhesion is found it is deemed a Treifa. The Rama, however, records the Ashkenazic custom to rely on certain tests and examinations, such as rubbing and pulling at the adhesion. If the adhesion teras as a result then it has proven not to be a true problematic adhesion, and the animal is deemed kosher. The Rama concludes that this became the accepted custom of Ashkenazic Jewry and one should not protest against those who follow it.
What Is “Glatt Kosher”? Historically among Ashkenazim, there were two categories:
- Meat from animals with smooth lungs. This can also refer to animals that possess only the mildest form of adhesion, one that could be removed effortlessly without any force by the bodek. Many Kashrus authorities classify these as mere mucus-like formations rather than significant sirchos.
- Meat that remained kosher after the accepted Ashkenazic examination and testing process.
What Is Chalak Beis Yosef? Chalak Beis Yosef reflects the stricter Sephardic tradition associated with the rulings of the Beis Yosef. According to this approach, the goal is to ensure that the lungs are genuinely smooth and free of problematic adhesions, without relying on the leniencies commonly accepted in Ashkenazic communities. For this reason, Sephardic communities generally prefer and often require Chalak Beis Yosef meat.
Why Is There So Much Confusion Today? Part of the confusion is that modern kashrus marketing often uses these terms somewhat differently than they were used historically. Rabbi Moshe Yehuda Leib Landa obm explained that historically meat from an animal that had no sirchos whatsoever was called “Glatt” or “Chalak” (“smooth”). Meat that originally had sirchos but was later found kosher through the accepted Ashkenazic process of examination and removal was simply called “Kosher.” However, as public demand for “Chalak” meat increased, many kashrus organizations began expanding the definition of Chalak to include various types of very minor sirchos. As a result, what was being sold as “Chalak” was not always literally free of every lung adhesion. His father, Rav Yaakov Landau, strongly opposed changing the traditional definition. He would say: “Chalak is like the calf was born, without any re’usa (defect) whatsoever.” Accordingly, under the Landau supervision,”Chalak” remained reserved for meat that had absolutely no sirchos or other lung defects at all. Due to shortages of perfectly smooth cattle, Rav Moshe Yehuda Leib Landau decided to market a second category called: “Kosher Glatt” (כשר גלאט). This referred to animals that did possess only the mildest form of adhesion, one that could be removed effortlessly without any force by the bodek. Many Kashrus authorities classify these as mere mucus-like formations rather than significant sirchos.

Which Should One Eat?
- Sephardim generally follow the standard of Chalak Beis Yosef.
- Ashkenazim have traditionally relied on the rulings of the Rama and the longstanding Ashkenazic custom to eat regular Kosher meat, not Glatt.
- Many people today, even Ashkenazim, choose to eat only Chalak or Glatt meat as a higher standard of kashrus.
