What challenge did the expanding practice of food dating create for consumers in the late 20th century?

Answer

The sheer variety of dating language used by different manufacturers created confusion

As the practice of dating foods became more widespread in the latter half of the 20th century, the central obstacle for the average consumer was not the absence of a date, but the proliferation of inconsistent terminology. Different companies used various phrases—such as 'Sell By,' 'Best By,' or 'Use By'—to communicate essentially the same underlying concept of suggested freshness. This patchwork system meant that a shopper had to understand the specific, unwritten industry convention associated with each product type to correctly interpret the label's meaning.
