Inspectors find mould in dishwasher, a greasy pipe and 'dirt traps'... but still bump up Old Trafford's food hygiene rating after raw chicken saga

Manchester United has trumpeted 'significant improvement work' which has seen it's food hygiene rating rise from one to four stars.

The club suffered the embarrassment of seeing its food hygiene rating slashed from a five to a one star rating after hosting a health and safety event in November last year when raw chicken thighs were served to 30 people. Inspectors ruled the food served was 'unfit for human consumption'.

After a follow-up inspection, today (Friday) the Food Standards Agency (FSA) bumped its rating back up to four stars, one shy of the top mark. The official report praised the progress but highlighted a handful of problems including mould in a dishwasher, a greasy gas pipe, a 'dusty' extraction fan and old labels which were 'becoming a dirt trap'.

The council hygiene inspector noted in the report: "A review of the actions taken by the club following the incident in November was undertaken. The club has undertaken a lot of work since this, however, the continued demonstration of the implementation of the revised procedures is required to enable the confidence in management score to be increased further."

The club has 28 kitchens serving 250,000 people at games and other events every year and, until November, had enjoyed a five-star food hygiene rating for eight consecutive years.

The full re-inspection in February found 'mould growth' on the upper jets of a dishwasher as well as 'debris' inside the jets, according to the Trafford Council inspection report. A gas pipe behind a grill in the Salford Kitchen was said to be 'in a greasy condition'.
