A laryngectomy is the partial or complete surgical removal of the larynx, usually as a treatment for cancer of the larynx. It may be complete (total) or partial. The type of surgery you have will depend upon the location and extent of the tumor within your larynx.
I'm going to go technical on you here so bear with me. If you can lower the temperature of you mac and cheese below 6 degrees celcius under 4 hours from oven hot (a feat that requires a blast chiller) you can safely store your food for 4 days and eat it cold, 5 to six days if you reheat it up to atleast 65 degrees. The unsafe zone is between 52 and 8 degrees where bacterie multiply the fastest.
Shelf Life of Nacho Cheese Sauce. Store-bought nacho cheese sauce will last up to four weeks in the refrigerator, while homemade cheese sauce will last only about four days. Store it in an airtight container to keep out moisture and contaminants. To keep it for longer, you can freeze nacho cheese sauce before it expires -- but be aware that freezing it may negatively impact the texture. Plan to use frozen store-bought nacho cheese sauce within three months or frozen homemade sauce within six months.
