Birmingham's Bullring Indoor Market will be shut all day Tuesday over fears there is a vermin infestation at the ten-year-old building.
Environmental health and pest control officers were called out after mouse and cockroach droppings were spotted in the market.
All of the 140 stalls will be shut to customers from 9am-5.30pm, while an intensive deep clean operation is carried out.
Alan Docherty, vice-chairman of the Indoor Market’s Traders Association and a market butcher for 35 years, said most traders would be “devastated” over the closure.
He said: “Pests are a problem, especially the cockroaches. We’ve had a few traders notice them in the past month.
“The market does need to be cleaned, but it could have been done over the weekend when it was less disruptive. Most businesses are already suffering with the poor economy and struggling to get by on six-day trade.”
The Bullring Indoor Market opened in October 2000 and sells a variety of produce including fruit and vegetables, confectionery, household goods, clothing, fish and meat. It opens from Monday to Saturdays, unlike the Outdoor and Wholesale Markets which close on Mondays.
Steve Grogan, head of market services, said he agreed to let officials shut the building to allow a one-day intensive deep clean of the site to take place.
He said traders had noticed there was a problem with mice and cockroaches behind the scenes with some stall-holders seeing a “few mice” scurrying in corners.
“There is a robust monitoring procedure in place because of the types of products on sale such as tropical fruit and vegetables.
“The market is a big building and with any similar-sized building, it is vulnerable to mouse infestation.
“We spoke to traders available and decided to take immediate action to nip the problem in the bud.”
A Birmingham City Council Spokesman said droppings had been found “out of the public area” behind the scenes at the market.
The Bullring Outdoor Market, Rag Market, and Wholesale Market are all unaffected and will open on Tuesday as normal.
And the Indoor Market is expected to open for business as usual on Wednesday.
