The Bristol Dry Gin Micro Distillery apologised to the families of Ms Sturgess and her partner Charlie Rowley - who is now said to be "conscious" after also being exposed to the Russian nerve agent - and claimed the product had been in the pipeline before the latest tragedy near Salisbury.
Lorna Wilkinson, director of nursing at the hospital, said on Tuesday: "We have seen a small but significant improvement in the condition of Charlie Rowley".
Ms Sturgess died as a result of the exposure and her family have paid tribute to the mother of three, calling her "a gentle soul who was generous to a fault".
The British government has accused Russian Federation of being behind the attack on Mr Skripal, who settled in the United Kingdom after a spy swap.
Mr Rowley has regained consciousness and is in a serious but stable condition in hospital.
Sally Davies, Britan's chief medical adviser, also said the threat to the public is low but reinforced warnings to residents of Salisbury and Amesbury against touching stray containers, syringes, needles, cosmetics or similar objects. "Charlie is still very unwell and will continue to require specialist, round-the-clock care here at Salisbury District Hospital".
It was unclear if Williamson was referring to the attack on the Skripals or a new attack.
The pair were found collapsed at Sturgess' Amesbury home on June 30.
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. She had two sons, aged 19 and 23, and an 11-year-old daughter.
Last night police seized a auto in Swindon in connection with the Novichok poisoning in Amesbury.
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.
Police now believe the two handled a contaminated item with a high dose of Novichok, although they have not been able to confirm if it was from the same batch as the one used in the attempted murder of the Skripals.
The BBC understands Mr Rowley's flat is regarded as the key location in the search.
