His arrest followed a raid on a remote farm in the North West province, where police said they uncovered a large methamphetamine laboratory worth about a billion rand ($60m).
This case is one of many that point to a pattern taking shape in rural areas of South Africa.
The Swartrugens laboratory was not an isolated discovery.
It was one of four major meth sites linked to Mexican criminals uncovered in South Africa in just two years, a pattern that has troubled investigators and organized crime experts.
In 2024, police destroyed a large meth facility worth approximately $105–110 million on a farm near Groblersdal in Limpopo. Later that year, another laboratory worth approximately $5–6 million was discovered near Tshwane, followed by arrests in Mpumalanga the previous year.
Then came the Swartrugens.
When police went to the North West farm in May, they found 481 kilos of methamphetamine, containers of chemicals and firearms. Those arrested included Mexican nationals Fabian Astorga, Jesus Alonso Medina Astorga, Luis Alberto Ramírez Ríos, José Andrés Medina and Jacqueline López Madrid, as well as a co-accused South African.
All sites followed the same pattern: remote farmland, long distance from cities, and sufficient isolation for criminal activity to go undetected.
For investigators, this pattern is becoming increasingly difficult to ignore.
Mexicans are increasingly being found working with local collaborators in rural production sites, suggesting a shift from smuggling meth into Africa to producing it there.
Organized crime researcher Julian Rademeyer told Al Jazeera that the model reflected a deliberate strategy.
“It’s quite a unique development where members of the Mexican drug cartels are franchising, taking chemists out to remote rural areas and farms,” he said.
He said this vision has been in the making for more than a decade.
The logic is straightforward: produce closer to consumers, cut transportation costs and reduce the risk of border and maritime enforcement.
how it spread
Mexican-linked networks in Africa did not originate in South Africa.
Researchers trace the initial activity to Nigeria, where local groups were producing meth with Mexican involvement around 2016.
From there, the network spread into East Africa, then south through Mozambique and Botswana, before recently reaching South Africa.
For years, users on the streets have been talking about “Mexican meth,” which is often considered imported. That supply chain has now shifted inward.
“Now, basically, cartel chemists are being sent here,” Rademeyer told Al Jazeera.
Analysts say multiple supply routes now feed the South African market, but the most significant change is the increase in local production.
who looks away
Methamphetamine dominates parts of South Africa’s illicit drug market because cheaper drugs such as cocaine and heroin are out of reach for many users, creating a steady demand for cheap, highly addictive stimulants.
Crime expert Willem Els says the demand is only part of the story.
“The main reason why manufacturing at the local level is attractive to cartels is because of the existing local conditions, where there is protection from corrupt police and politicians,” he told Al Jazeera.
“It’s very lucrative. Cartels can make a lot of money because South African conditions result in anonymous and protected operations.”
A separate commission of inquiry into law enforcement has heard testimony alleging deep corruption within policing structures, including missing drug consignments and suspected insider involvement in major cases.
In one case under investigation in 2021, 541 kg of cocaine was seized and later stolen from a police facility in what investigators believe was an inside job.
Andy Mashiyale, a former Interpol ambassador, told Al Jazeera that the problem is visible on the ground.
“There’s no way the police don’t know about those labs,” he said. “So corruption plays a role.”
He said officers deployed in rural areas were often aware of suspicious activity but failed to act.
“What motivates drug manufacturers or drug cartels is the desire of the police to prevent the drug trade from occurring,” he said.
South Africa’s elite Hawks unit says recent raids show progress in disrupting the network, while international partners including the US Drug Enforcement Administration have provided intelligence linking some suspects to the Sinaloa cartel.
But investigators warn that the systems behind the labs are flexible.
a limit that goes on
US Africa Command officials have warned that Mexican cartels are now not only moving drugs through Africa, but also producing them on the continent.
For South Africa, the challenge is no longer just border control, it is institutional capacity, intelligence and corruption within the system that is designed to control it.
Analysts warn that without deeper reforms, this pattern is likely to continue: new farms, new laboratories, new chemists quietly arriving in rural provinces.
For the five Swartugens, the question is immediate whether they will be released.
For South Africa, the question is bigger and more difficult: how to regulate a trade that is no longer coming to its borders, but is taking root in the country.
Rademeyer says the structure is built to absorb disruption.
“It’s a strange game,” he told Al Jazeera. “You seize a meth lab here, you seize a meth lab there. They’ll emerge somewhere else.”
