500 people who visited pubs and restaurants in Salisbury should wash possessions following nerve agent attack it has been warned.

Chief medical officer Dame Sally Davies says up to 500 people who have visited pubs and restaurants in Salisbury should wash their possessions as a precaution after traces of the nerve agent used to poison former Russian spy Sergei Skripal and his daughter Yulia were found.

She said: “We have now learned there has been some trace contamination by the nerve agent in both the Mill Pub and Zizzi restaurant in Salisbury.

“I am confident this has not harmed the health of anyone who was in the Mill pub or Zizzi’s.

“However, some people are concerned long term exposure to these substances may over weeks, and particularly months, give rise to health problems.

“I am therefore advising as a belt and braces approach the people who were in either the restaurant or the pub at 1:30pm last Sunday until evening closing on Monday should clean the clothes they wore and the possessions they handled while there.”
