Beyond the text on the plastic wrap, the physical characteristics of the meat itself tell a story that cannot be faked. Color is the most immediate indicator of freshness, but it requires a nuanced understanding. For instance, fresh beef should be a vibrant, cherry-red color; if it has turned a muddy brown or a dull grey, it is a sign that oxidation has begun, and the meat is past its prime. Poultry should appear pink and translucent, never greyish or yellow-tinted. Pork should be a light, rosy pink. Texture is equally telling. Fresh meat should be firm to the touch and possess a certain elasticity; if you press into it and the indentation remains, or if the surface feels slimy or tacky, the bacterial load has likely reached a dangerous level. Perhaps the most reliable sense is the sense of smell. While vacuum-sealed meat may have a slight tang upon opening, any scent that is sour, ammonia-like, or “off” is a definitive signal that the product is unfit for consumption.
