Mouse poo was found in the kitchen at Drayton Manor High School's canteen in Hanwell which also had a "historic pest problem", a report reveals.
The academy school's caterer, Olive Dining Ltd, was given the lowest possible food hygiene rating of zero on November 25 last year.
It came after Ealing Council , who since said all safety concerns have been addressed, received a complaint that rodents had been spotted in the kitchens.
Now getwestlondon has seen the hygiene report, which states there was a "historic pest problem" on site.
The report, obtained via a Freedom of Information (FOI) request, adds that mouse poo was found in the kitchen and on a wrapped packet of smoked salmon.
It reads: "Mouse faeces found throughout the kitchen plus store rooms and mouse faeces also found on wrapped packet of smoked salmon.
"Mouse faeces found at low levels in the kitchen and adjacent store rooms. Mouse faeces found around motors of blast chiller (in kitchen) and front service fridges.
"Large gap found around exit doors from kitchen to external areas, which could allow for the ingress of pests on site.
"It has been noted by reviewing pest control records that there is a historic pest problem on site.
"Mouse dropping found on open pack of smoked salmon which had been wrapped with cling film."
An inspection on November 28, also seen through an FOI request, determined there was no pest activity and preventative measures were in place.
It reads: "No activity found on site plus significant pest proofing plus cleaning and disinfection carried out."
The school, which opened in 1930 and caters from pupils in Years 7 to 11, as well as Sixth Form, said the rodent complaint was lodged on a staff training day.
But the council said it is "now satisfied that there is no risk to public health" and removed its third-party inspectors from its contract.
This came after its inspectors had given the canteen the highest possible hygiene rating of five only a day before the zero-rated report.
Head teacher, Sir Pritpal Singh, wrote to parents on February 3 to say the school, rated "outstanding" by Ofsted, had sought a speedy re-inspection.
Sir Pritpal said the school sought professional advice to get a re-inspection sooner that the six months estimated by the council, from point time the November 25 report.
The council initially said it had not received a request for an earlier re-inspection when getwestlondon first published the result of the report on Monday (February 6).
But since then, it has confirmed the school has requested re-inspection.
Sir Pritpal Singh told getwestlondon: "The operator is our independent caterer. Our caterer did not request a revisit because they knew the school had and we certainly did.
"We are pleased to say that Ealing Council has now agreed to expedite inspection.
"We are satisfied that we provided the right level of detail to parents, bearing in mind that the issue had been rectified and full details were already publicly available.
"Any parents who seek further details will be referred to that material. We sought advice on this and acted in accordance with it."
