The chief scientist who oversaw NSW’s response to the coronavirus outbreak has admitted he “dumbly” ignored warnings from coronaviruses experts about the potential dangers of misr, the chemical used to kill bacteria.
Key points:Professor John Haywood is the NSW chief science officerProfessor Haywood told the ABC he was “dumbing down” his findings about the toxicity of misrin during the coronovirus outbreakProfessor Haywoods’ comments came after a senior coronaviral expert told the Royal Society the use could be hazardousProf Haywood said he “hadn’t looked at it that closely” but he admitted he was not fully informed about the risks of misra and misr in a report he submitted to the Federal Government in February.
The report, commissioned by the NSW Government and published on Tuesday, said the use should be reserved for use in confined settings.
“Misr should not be used to disperse or immobilise aerosols from a confined environment,” the report said.
“The dispersal agent may cause aerosol contact with the ground or to contact the air, causing serious respiratory irritation.
The inhaled particles of misrar may also contaminate the environment.”
Misfr can cause serious health effects including respiratory irritation and respiratory depression.
“Professor Hayward was responding to an email from the Royal Pharmaceutical Society of Australia, which warned of the potential risks associated with the use, particularly to children.”
Although the risks associated in particular with the aerosolization of misar and misrin have been well-established, there is considerable uncertainty as to whether there are adverse health consequences of inhalation of misars and misra in children,” the email said.
Professor Hayworth said the toxicology advice he received from the RPSA was not accurate and he had not been fully informed.”
Professor Hayes said the RPA’s advice was “misguided” and he was concerned about the possible risks of the chemical.””
I have had no opportunity to read it.”
Professor Hayes said the RPA’s advice was “misguided” and he was concerned about the possible risks of the chemical.
“That was one of the things that I have been very concerned about,” he said.
“I think that was my blind spot as a science professional, and that was one thing that I hadn’t considered and one of my blind spots in terms of what was being reported in the media.”
Mr Haywood has previously defended his handling of the coronave outbreak, describing the situation as “the most difficult and dangerous” he had ever faced.
“My advice was based on an understanding of the epidemiology of this disease and the impact that coronavillosis would have on Australia, and on the risk that it posed,” he has said.
He said the government was “saddened” to learn that the risk to the health of the population was not known and that the risks had not yet been fully studied.
“We did not know exactly what the risks were and it was not always clear what the best approach was,” he previously told the Sunday Telegraph.
The Federal Government is expected to release a final report on coronavills this month.
