Staff at Arsenal's Emirates Stadium have been sent for extra training on pest control after Sportsmail revealed the venue had been hit by a mice infestation.
Workers at Arsenal's ground - which we can disclose is one of only two Premier League stadia not to achieve a five-star hygiene rating - have seen experts as part of a wide-ranging attempt to tackle what has been described as 'an ongoing issue'.
The Gunners, who have also increased pest-proofing measures at the 60,000- capacity stadium, have been praised by inspectors from the local authority for making 'great improvements' in the area of pest control.
However, a number of issues were raised in the latest hygiene report carried out earlier this year.
Officers found mouse droppings in a number of areas and discovered that many staff were oblivious to the issue - with inspectors having to bring out torches to shine a light on the problem. A lack of cleaning was also criticised.
Along with the extra training and increased pest proofing, Arsenal also brought in an external company to carry out an audit.
The latest report highlights a failure of the doors to close properly in a central processing area, which inspectors say remains an 'important area of proofing outstanding'.
They also advise that the club's caterers should install foot-pedal bins in the kitchens, as chefs are currently using their hands to lift the existing wheelie-bin flaps, resulting in 'reducing the efficacy of frequent hand washing or, at busy times, leaving the lids open which encourages odours and pests'.
