The quality and longevity of fresh produce from UK grocery stores has been researched by consumer specialists at Which ?.
The search saw the country’s largest chain Tesco perform the strongest.
Who? deployed a team of 12 undercover shoppers who ordered more than 1,000 groceries from six major supermarket chains to examine the freshness of their food and drink.
The same 16 perishable grocery items were ordered by each shopper in each of the online supermarkets.
It totals the number of full hours remaining between delivery and midnight on the day of consumption for each item and calculates an average time per supermarket.
Tesco topped the rankings for freshness, with an average shelf life of its items totaling 11 days.
The supermarket giant has shown the expected shelf life of perishable items on its website and has had no cases of damaged packaging or food loss upon delivery, unlike some rivals.
Tesco was closely followed by Asda, which had an average shelf life of 10.5 days for its products on all grocery items – although a packet of bacon was delivered by its expiration date.
Ocado, online only, was just behind Asda, with an average product lifespan of 10.4 days.
Waitrose, whose online business launched last year after a partnership with Ocado ended, was at the bottom of the rankings with items averaging 8.6 days.
The supermarket also delivered two packages of beef that appeared to have died out, despite their expiration date.
Waitrose said, “We always train our partners to choose products with the longest expiration date for online deliveries – we’re sorry this didn’t meet our high standards and we’re committed to improving this to. our clients.
“From time to time we sometimes shorten the date codes on certain fresh produce to ensure optimum quality – so this may also have been a factor behind the results. ”
