Tesco supermarkets prove to be the worst for hygiene after it was revealed that 29 of its stores failed inspections aimed to protect customers from food poisoning.

It was one of five big supermarket chains that saw stores fall foul of basic checks from the Food Standards Agency (FSA), according to figures from between 2012 and 2013 that were published in the Sun.

Asda, Sainsbury’s, Morrisons and Aldi also had stores that failed to meet expected standards, according to the data.

Lidl and Waitrose were the only two ‘big seven’ chains which saw all stores pass.

The FSA reviewed hygiene practices at a total of 11,106 supermarkets in England, Wales and Northern Ireland. Of that number, 510 did not maintain standard levels of hygiene.
