Latest on Enyobeni tavern tragedy: How home-made beer led to the death of 21 teenagers

0

Police have been urged to trace the last movements of the 21 teenagers who died at a tavern in East London last month.

This after a toxicology report revealed methanol was found in their blood.

Methanol was commonly used by backstreet "manufacturers" to brew illegal alcohol, leading criminologist and forensic expert Paul O'Sullivan said.


It is unclear whether the children ingested the deadly substance at the Enyobeni tavern in Scenery Park or elsewhere.

Authorities were also not ruling out the possibility they might have gathered elsewhere to drink before going to the tavern in Scenery Park on 26 June.

O'Sullivan said:

All their respective movements in the 24 hours before their deaths are important and I am sure that the police must be trying to reconstruct their movements, if only from their respective phones. [There are lots] of questions to be answered and the ones that have most of the answers are no longer with us.

During a press conference in East London on Tuesday, Police Minister Bheki Cele and police top brass would not be drawn into speculating on the circumstances leading up to their deaths, only saying the case was still under investigation.

At the Cambridge police station, the Eastern Cape health department's deputy director-general of clinical services, Dr Litha Matiwane, said speculating about where the methanol came from and how the victims might have ingested it could interfere with the investigation.

At this stage, Matiwane added, they could not draw the conclusion the children ingested the methanol directly or as a by-product of something else.

A full and final report is not ready yet as toxicologists continue with their investigation.

Matiwane added while methanol was alcohol, unlike ethanol, it was not a base alcohol in drinking beverages.

"Methanol is a toxic type of alcohol to the body."

When asked for clarity, he said he could not expand on what he said because the case was still under investigation.

O'Sullivan said although methanol was similar to ethanol, it was commonly known as a "toxic alcohol" because it could be deadly.

He added by the time "you realise that you've ingested it, it may be too late to completely reverse the effects, other than with urgent haemodialysis of the blood".

O'Sullivan said methanol was often formed when brewing alcoholic drinks such as beer, wine, and spirits.

The amounts formed in beer and wine are usually extremely low and non-toxic due to the low concentrations.

When spirits were made by a licenced manufacturer, they performed regular tests to ensure methanol (and other harmful ingredients) was not present in the finished product, said O'Sullivan.

He added manufacturers also have sophisticated methods of removing methanol and other by-products during the manufacturing process, saying:
However, some people think they can make homemade spirits, but do not really know what they are doing and don't do it right. This is often the case with backstreet 'manufacturers' of alcohol.

O'Sullivan said if methanol was ingested, it metabolised to formic acid which had a number of industrial uses, like tanning or preserving leather.

He added it was also often used as an anti-bacterial product to ensure a longer shelf-life for certain animal feed.

However in the human body, formic acid, as a by-product of methanol, would quickly bring about severe symptoms that included circulatory problems, liver and kidney damage as well as blindness and death through a combination of the previous symptoms, O'Sullivan added.

Coincidently, he said, formic acid was also the main ingredient of certain ant stings.

O'Sullivan added methanol poisoning could result in abdominal pain, nausea, vomiting and loss of vision if a large enough amount was ingested.

The health department initially said it treated 16 survivors for headaches, vomiting, backaches and tight chests.

"Cellular hypoxia is also common, resulting in a change to the colour of the skin – 15ml of methanol can be lethal, although it normally takes more. If mixed with ethanol, the metabolic process can be masked," added O'Sullivan

Methanol can also be found in windscreen washer fluid and certain household cleaning chemicals, he said.

O'Sullivan added:
It is often found in illegally made alcoholic spirits, or in illegal 'cocktails' made by someone that thinks methanol is ethanol and is therefore okay to drink with mixers, as if it is whiskey, gin or vodka, or some other alcoholic spirit. Some people even believe it's ok to mix methylated spirits, or 'meths' with mixers. Methylated spirits is nothing more than ethanol mixed with methanol and other denatured spirits to make it suitable for cleaning or other chemical uses, such as stain removal or as a lamp fluid or for cleaning paint brushes.

Detection and treatment

He said one of the best ways to detect methanol poisoning was using gas or liquid chromatography.

This is both labour intensive and time consuming, but is the best method, although most labs do not have the relevant equipment.

The process will seek the metabolised product of methanol, formic acid.

The best treatment for methanol poisoning, if caught quickly, is haemodialysis, where the blood is cleansed of the metabolised formic acid and replaced in the body, thereby rapidly reducing the chances of long-term damage, or death.

Testing for methanol

If you suspected your alcohol might have been adulterated with methanol, you could put a small quantity into a saucer and set it alight, said O'Sullivan.

If the flame is yellow, it must be treated as suspect. Do not drink it.

Normal alcohol (ethanol) produces a blue flame, whereas methanol produces a yellowish one. This is a crude test and should not be used to determine the safety of any alcohol.

If you suspect an alcoholic drink may have been contaminated or adulterated do not drink it.

The above is a synopsis of methanol poisoning and is not to be considered exhaustive.
