Sponges and Dairy/Meat
Situation You inadvertently use a brush or sponge (hotter than 120° F--49° C) of one gender on a utensil of the opposite gender.
Status The sponge or brush becomes non-kosher, but ask a rabbi about the status of the utensil.
Kashrut: Fish: Dairy and Fish Together
You may cook and/or eat dairy-containing and fish-containing foods together. Sefardim do not eat dairy and fish together.
Sink Racks and Dairy/Meat
Two racks or other utensils, one dairy and the other meat--that are used in a single sink (whether together or sequentially) may become non-kosher if they ever reach more than 120° F (49° C) while in the sink. Consult a rabbi.
Baking COVERED/UNCOVERED Dairy and Meat Consecutively
Situation You cooked food of both genders:
  • In a clean oven,
  • In separate utensils,
  • UNCOVERED but consecutively (even within 24 hours).
    Note The first food must be removed before the second one is put into the oven.
Status
  • If one or both are solid (non-liquid) at either the beginning OR end of the cooking OR both beginning and end:
They are both kosher; both food and pan.
  • If they were both liquid:
The second one is probably not kosher (both food and pan), but consult a rabbi.
Note
  • If both are covered, they are both kosher.
  • If the first one to be cooked was covered, they are both kosher. 
  • If the first one was uncovered, they may both have become non-kosher--consult a rabbi.
Introduction to Kashrut: Dairy/Meat: Baking at Same Time
Five factors affect cooking separate pans of dairy and meat in an oven at the same time (these are all b'di'avad cases):
  • Covered 
  Is either pan (or both) covered?
  • Outside Clean and Dry
  Are both pans clean and dry on the outside?
  • Food Non-Liquid (“Solid”) 
  Are the contents of one or both of them non-liquid (solid before OR after cooking
  OR both)?  That is, one or both are non-liquid (“solid”) at:
  • The beginning of the cooking,
  • The end of the cooking, OR
  • Both beginning and end of cooking.
  • Pans Touching 
  Are the pans touching?
  • Spicy/Charif
  Are the contents spicy/charif?
 
Kashering a Dishwasher from Dairy to Meat, or Vice Versa
You may not kasher a dishwasher (even if it is stainless steel) from dairy to meat, or vice versa, in order to use the dishwasher for dairy and for meat utensils, even sequentially.
Separate Oven Mitts for Dairy and Meat
Use separate oven mitts for each gender.
Reason Oven mitts assume the gender of any hot food that spills on them. This could make them non-kosher and cause future utensils to become non-kosher.
 
Steam and Utensils of Dairy/Meat
Situation Steam of one gender touched a utensil of opposite gender.
What To Do  Ask a rabbi.
Cold Condiments Used for Dairy and Meat
B'di'avad, you may scoop out mayonnaise or mustard and spread it on meat and then scoop out more and then later use same condiment on dairy foods (and the same for dairy and later on meat) as long as any residual food is less than 1/60th of the total volume of food. But the preferred practice is to have two separate containers, one for dairy and one for meat foods.
 
Refrigerators and Hot Pots of Dairy/Meat
Hot pots on a refrigerator shelf with pots of the opposite gender that touch each other are only a problem if wet. There is no problem if they are:
  • Both cold, or
  • Even if they are spicy.
Asking a Halachic Authority about Dairy/Meat Errors
The halachic category of dairy and meat errors, while extremely complicated, has many conditions for which leniency may be applied. Here are the main points a halachic authority (posek) will need to know:
  • Was the food or utensil hotter than 120° F (49° C)?
  • Had the utensil been used for hot food (over 120° F) within 24 hours?
  • How much food was involved?
  • What was the relative volume or quantity of the food and utensils? (1/60th of relevant volumes?)
  • How much food is normally cooked in the utensils?
  • Of what materials are the utensils made?
  • Was the food spicy (hot peppers, garlic, onions, lemon...)?
  • Was the food needed for Shabbat meals?
  • How much does the food cost?
 
No Eating, Cooking, or Benefiting from Dairy with Meat
You may not cook or eat dairy and meat foods together, even when they are individually kosher.  You may not even derive any benefit from their being cooked together.
 
Baking Non-Liquid Neutral/Pareve and Non-Liquid Dairy (or Meat) at Same Time
Situation You bake non-liquid dairy food and non-liquid neutral/pareve food in one oven at the same time.
Status
  • You may not eat the pareve food with meat food (and certainly not dairy food with the meat!), but
  • The utensil (pan) of the pareve food does not become dairy.
Note The same applies if you cook non-liquid meat with non-liquid pareve food.
Note If one or both of the foods were liquid, the utensil might be non-kosher. Consult a rabbi.

Frozen Food in Non-Kosher Oven
Frozen food is considered to be wet food regarding cooking it in a non-kosher oven or regarding its being neutral for dairy and meat issues: If the oven is not kosher, the frozen food must be double wrapped, even if the oven is clean.
Microwave Oven: Kosher Status
If a microwave oven's walls/floor/door do not become hot (more than 120° F, or 49° C), the microwave oven does not become non-kosher, dairy, meat, or non-Passover/chametz.

A microwave oven that does not normally get hot, may get hotter than 120° F if you cook:

  • A liquid or moist food for a long time (even if less than 10 minutes),

  • Several liquid or moist items sequentially, or

  • Popcorn and similar foods.

If a microwave oven's walls/floor/door get hot, the oven can become dairy, meat, or non-kosher (if they become one gender and then the opposite gender is cooked or if non-kosher food has been cooked in it). If any surface--including walls, door, floor, etc.--that gets hot are plastic or coated metal, it cannot be returned to kosher or pareve. However, if the surfaces are all made of metal, they may be kasherable. Consult a rabbi.
NoteIf microwave oven does get hot, it cannot be kashered at all--not for Passover and not from non-kosher to kosher. To check if your microwave oven gets hot, see How To Check If a Microwave Oven Will Get Hot during Cooking.
