What final piece of advice is given to the shopper when evaluating older food items based on voluntary tradition?

Answer

To engage senses: look, smell, and then taste

Given that the US food dating system remains largely decentralized and rooted in voluntary quality suggestions dating back to the 1930s (outside of infant formula), the ultimate guidance provided to the consumer facing older packaged food is sensory evaluation. Before relying solely on faded ink, which represents a quality suggestion from the company, the shopper is encouraged to engage their senses sequentially: first looking at the product for signs of visual spoilage, then smelling it, and finally tasting a small amount to confirm its edibility, as the sensory assessment often trumps the printed quality marker.
