There is a "huge variation" in food hygiene standards across the UK, according to a Which? investigation launched in the wake of the horse meat scandal.
Food testing by local authorities fell by 6.8% over the past year, the group found.
The investigation by the consumer group into 395 local authorities across the UK used Food Standards Agency data and found:
- Bexley in London was the poorest performing local authority, with five other London councils in our bottom 10 (Ealing, Enfield, Harrow, Richmond upon Thames and Southwark).
- Cherwell District Council in North Oxfordshire was rated as the best performing local authority.
- No official hygiene sampling was carried out at all by Bexley, Christchurch, Isles of Scilly, Medway, Tamworth, West Lindsey and West Yorkshire in 2012/13.
- The overall testing rate fell by 6.8% in 2013.
- Testing for labelling and presentation fell by 16.2%
