Dawn Sturgess, 44, died in hospital at the weekend and her partner Charlie Rowley remains critically ill in hospital.
A Bristol company came under fire for its "Novichok" vodka when its launch coincided with the death of Dawn Sturgess after exposure to the notorious toxin.
The main line of inquiry is whether it is linked to the attempted murders of former Russian spy Sergei Skripal and his daughter Yulia in nearby Salisbury in March. Russian officials have denied involvement.
Ms Sturgess, who had a daughter aged 11 and two sons aged 19 and 23, had...
"I want to emphasise to everyone in the Salisbury and Amesbury area that nobody, adult or child, should pick up any foreign object which could contain liquid or gel, in the interests of their own safety", she said.

"She had the biggest of hearts and she will be dreadfully missed by both her immediate and wider family".
Charlie Rowley, 45, woke up Tuesday at Salisbury Hospital in London.
Ms Sturgess collapsed at about 10:15am and was taken to hospital in an ambulance and Mr Rowley was taken to hospital later that day.
"While this is welcome news, clearly we are not out of the woods yet".
Residents also claimed he had told them both his vehicle and his clothes were being taken to the government laboratory at Porton Down to be destroyed.
Wiltshire Police tweeted on Monday (Tuesday NZ Time) that the auto was being "safely" removed and reminded the public that the risk of contamination with the agent was low.
A team wearing protective clothing is combing the small flat, working in 30-minute shifts because of the heat.
He said no one else in the Amesbury and Salisbury region, where the couple lived in southwestern England, has shown any sign of Novichok poisoning.
Central to the investigation is John Baker House, the supported-living accommodation where Ms Sturgess lived; Mr Rowley's home in Amesbury, and Salisbury's Queen Elizabeth Gardens, which remains cordoned off.
