Subway has scored 0 out of 5 for hygiene at two of its UK branches -- and its other locations aren't much better

The next time you fancy a footlong sub for lunch, you may want to think twice.

In certain UK locations, popular fast food chain Subway has scored extremely low on hygiene — with some of its branches ranked as low as zero out of five, the worst possible score according to the Food Standards Agency (FSA).

A documentaryon Channel 4 titled “Tricks of the Restaurant Trade” will air on Monday revealing the results of the channel’s investigation into hygiene standards at high street restaurants, according to the Daily Mail.

Subway, which has over 2,000 branches in the UK, currently operates 45 restaurants where food hygiene standards were found to fall below level 2, according to the FSA, which considers a level 3 or above to be satisfactory.

33 of Subway’s UK branches are categorised as level 2 in the hygiene stakes, while 10 are at level 1, and, shockingly, two — its Granby Street branch in Leicester and Roade Service Station in Northamptonshire — were ranked as zero out of five.

Other offenders include Frankie & Benny’s, which has seven restaurants with sub-standard hygiene ratings — five of its branches are ranked at level 2 and two at level 1.

The show will also reveal that a branch of Marco’s New York Italian, a bistro chain owned by celebrity British chef Marco Pierre White at the Mercure Hotel in central London, scored just two out of five.
