Mark Watson, who represented Tesco in court said the company had invested in "procedures and systems" to correct the problems and insisted the problem was with local management.
A shopper first noticed a mouse in the store in March last year, and reported it to Westminster Council.
The hearing at Southwark Crown Court heard that:
- Mice were found gnawing on pieces of raw chicken which had been contaminated by droppings
- They gobbled ribs, sausages, hot and spicy wings
- Droppings were also found in an aisle of the store close to the pick 'n' mix section
Tesco has been fined £45,000 after a 'super mouse' was discovered in a filthy store in central London, plagued by an infestation of rodents.
The creature, which was twice the size of a normal mouse, was spotted by a horrified health inspector at the Tesco Metro store in Covent Garden where 55,000 customers shop each week.
