John Miller from the United States Office to Monitor Trafficking in Persons calls human trafficking: "The greatest human rights challenge of our generation."

But is this really the current position in South Africa? Let us do a reality check. New evidence-based insights were gained from convictions in several adult, as well as 25 child trafficking cases. 

In 2011, Roelofs penned a picture of (sex) trafficking: 

"It is a product of an increasing sex obsessed world with billions of dollars being earned from pornographic magazines, television channels and prostitution all because of slumping morality. It is obviously a very lucrative business. Whereas drugs and other narcotic substances can be used only once; a girl used as a sex slave can be sold over and over. This is the tragedy of this cruel exploitation of the vulnerable in our societies."

Exploitation of the vulnerable for financial gain

In 2019, in S v Ediozi Obi (case no CC40/2018), judge Natvarlal Ranchod referred to the above quote and concluded: “This is tragically illustrated in this matter before me …” In this case, several victims were vulnerable young children. They were trafficked, groomed, and repeatedly raped. “They were prostituted for accused 1's financial benefit. It is a sad indictment of certain members of the police force who were expected to bring perpetrators to book but instead, exploited the situation to their own advantage by taking bribes and themselves taking advantage of the young victims. This is some of the evidence that came out in this trial.” 

In 2017 in S v Adina Dos Santos, the trafficker was sentenced to life imprisonment, which was confirmed on appeal. The evidence was that the trafficker promised minor Mozambican girls work in her hair salon in South Africa and an opportunity to study while working there. The girls, who were looking for a better life, were eventually threatened and forced to use narcotic drugs and then have sexual intercourse with several men daily. Recently, two female traffickers were sentenced to 19 life sentences in S v Seleso for sexually exploiting a minor girl online by advertising her sexual services to clients on a website. 

A multitude of human rights are being violated in human trafficking scenarios. It ranges from violating the right to dignity, privacy, and life, to the right to be free from all forms of violence and not to be treated in a cruel, inhuman, or degrading way. – Prof Beatri Kruger

The trafficking convictions further confirmed that, apart from sex trafficking, victims are also trafficked for other purposes in South Africa. Children as young as eight were trafficked from Mozambique and Nigeria to be exploited for labour purposes. The cases further confirmed that traffickers use an aberrant form of the ukuthwala custom as a guise to traffic minor girls into forced marriages. Furthermore, children were kidnapped and sold. A young mother even advertised her baby on Gumtree for R5 000.  

Multitude of human rights are violated in human trafficking

This is a snapshot from our case law. Despite the culture of human rights enshrined in our constitution, it is clear that a multitude of human rights are being violated in human trafficking scenarios. It ranges from violating the right to dignity, privacy, and life, to the right to be free from all forms of violence and not to be treated in a cruel, inhuman, or degrading way. Judge Ranchod rightly declared in S v Obi that human trafficking violates basic human rights and is the cause of immeasurable trauma for victims, their families, and the communities in which they live. Protecting trafficked persons and their human rights is crucial – we have a great task ahead.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
