In a major break from tradition, eggs are to be sold in boxes of seven rather than the usual six to provide one egg for each day of the week.
Eggs have been sold in half-dozen boxes since the 1930s. The new boxes, which are circular in order to accommodate the extra egg, could be on shop shelves within the next few weeks.
Andrew Parke, from the British Egg Information Council, told the Evening Standard: “It might take shoppers by surprise but we think they’ll get used to it very quickly.”
The change comes as part of the council’s “egg-a-day” campaign to do away with the commonly held belief that eating more than three eggs a week can be bad for people’s health.
