10 Milk that was found in the stomach [of the animal] from the outset one should not leave it in the stomach until the milk that's in the stomach cools off, but after the fact, there is nothing to worry about until it was salted in the stomach, or it stood in it for a full day, [then] it is forbidden to curdle milk with it. Rema: And if one did curdle milk with it, if it was liquidy, the entire cheese is forbidden unless there was sixty times the amount of [permitted] milk that one made curdled with against the forbidden [milk] from the stomach. And if there was sixty times the milk it is all permitted. And if the [milk in] the stomach was solidified, it does not forbid [the cheese] at all even if there wasn't sixty times the [permitted] milk against the [milk in] the stomach. And if the [milk in] the stomach was liquidy at first and became solidified, it has the law of liquidy [milk]. And there are those that are lenient in this matter, and in a case of monetary loss, there is room to be lenient. The skin of the stomach, sometimes they salt it and dry it out and it becomes like wood and they fill it with milk, [in this case the milk is] permitted, since after it was dried out it is like mere wood, and it has no moisture of the meat in it.
