Mishnah Ḥullin
1. All meat is forbidden to be cooked with milk, except for the meat of fish and locusts. And it is forbidden to put it on the table with cheese, except for the meat of fish and locusts. One who vows [to abstain] from meat is permitted [to eat] the meat of fish and locusts.
Fowl may be put on the table with cheese, but it may not be eaten—the words of Beth Shammai. But Beth Hillel says: It may neither be put [on the table], nor may it be eaten. R. Yosi said: This is one of the lenient rulings of Beth Shammai and the stringent rulings of Beth Hillel.
What kind of table were they speaking about? A table at which one eats. But regarding a table upon which one arranges the food, one may put one beside the other without concern.
2. A person may wrap meat and cheese in one cloth, provided that they do not touch one another. Rabban Simeon ben Gamaliel says: Two guests may eat at one table, this one meat and that one cheese, without concern.
3. [Regarding] a drop of milk that fell on a piece [of meat cooking in a pot]: If there is in it [a sufficient amount] to impart flavor to that piece, it is forbidden. [If] one stirred the pot, then if there is in it [a sufficient amount] to impart flavor to the entire pot, it is forbidden.
[Regarding] the udder: one tears it open and removes its milk. [If] one does not tear it open, one does not transgress on its account.
[Regarding] the heart: one tears it open and removes its blood. [If] one does not tear it open, one does not transgress on its account.
One who puts fowl on the table with cheese does not transgress a negative commandment.
