I thought milk and butter are highly unlikely to cause any harm or distress that you wouldn't notice from spoiled taste.

Meat as well but you have to be accustomed to how raw meat is supposed to smell which may be more pungent than you think.

Trust your nose. The date isn't a guarantee. I have had food within the expiry date that seemed off, I ate anyway, and it made me sick.

Meat in the US is highly processed. It generally receives colorants, shaping, or processing depending upon the meat and where you buy it from. Deli meats for example are shaped loaves of meat for easier cutting and different flavorings. A butcher is generally the best bet for getting actual meat and they typically cut the meat the same day as you get it for maximum freshness.
