Opinion article by Prof Sethulego Matebesi, Associate Professor and Academic Head of Department of Sociology, University of the Free State.


There was a time when weekly news coverage of South Africa was dominated by various forms of racism, racial discrimination, xenophobia, and related intolerance incidents that painted a grim picture of respect for human rights

However, in the history of contemporary South Africa there has been plenty of optimism about the prospect of deepening the understanding of human rights in order to entrench a human rights culture among citizens. This optimism is underscored by a range of deliberate actions by the South African government to promote, protect, and monitor the development and observance of human rights through, for example, the South African Human Rights Commission and the Commission for Gender Equality.

Yet, while these institutions – and many other policy instruments to ensure compliance – are central to creating an environment conducive to advancing rights enshrined in the Bill of Rights, citizens also hold significant responsibility to prevent the escalation of discrimination and racial tension. But many of us face an uncomfortable truth we have become accustomed to avoiding: the ability to show unusual restraint in the face of injustice.

The challenge of combating practices that glorify intolerance

Beyond formal political rights, human rights also entail the progressive realisation of the right to the structural social determinants of well-being, such as access to clean water, food, and a healthy environment. However, while the process of social change in South Africa has many unique attributes, the response to the process reflects two extremes.

There are, on the one hand, those who cultivate an image as defenders of the rights of the ‘oppressed’ and are predominantly black activists, and on the other hand, anti-transformation forces who stall the move of the country towards a more inclusive and egalitarian future and are primarily white activists. These activists, whether advancing the reclamation of rights, perpetuate legacies of the past instead of asserting a positive commitment to eradicating socially constructed barriers to equality.

These activists are found everywhere. They are part of our education, religious, political, and social establishments. Reflecting on the painful past of the country, these activists do not help foster diversity as an ethos but advance the conscious and unconscious practices of structural racism. Aided by hyper-personalised social media feeds, these activists can stretch the boundaries of logic and destabilise fragile and established democratic and human rights.

The problem, they claim, is that those who embrace diversity and want to find amicable solutions to longstanding social injustices are either advocates of white supremacy or want to abrogate their right to freedom of expression. In such cases, when people in a hate frenzy find something to hate together, they become bonded. And anything contrary to their beliefs goes into an echo chamber of mockery. 

I do not want to establish a potentially trivialising affinity with branding activists who assert their rights as an attack on human rights. But attention is drawn to instances where noble objectives to confront the tentacles of human rights abuses have been weaponised against what is perceived as ‘the other.’

But how can we navigate this fundamental societal defect? Collective agency to advance the ethos of human rights

After three decades of democracy, attempts to eliminate systematic and institutionalised under-privilege must be welcomed. Likewise, our response to the perceived threats to efforts to enhance diversity as an ethos in public institutions and society matters. In many instances, when subjugated to hatred, hostility, or even violence, there is a tendency to believe that the best approach to such an absurd situation is more absurdity. At its most benign, such a response is not helpful to efforts to embrace diversity. At its weirdest, it garners public sympathy for hate groups and activists.

While there have been concerted efforts internationally and nationally for the progressive realisation of social rights and efforts to strengthen democratic resilience and rights-respecting societies, South Africans have been passing the buck. Rights-respecting citizens have a choice to make. They can continue to pass the buck or help build a culture where everyone achieves their potential and develops into responsible citizens.

I am convinced that beyond formal politics, the attainment of respect for cultural diversity and professing the freedom, equality, and unity of all peoples are contingent upon our collective activism and shared commitments to these values. This collective approach – although some may view it as illusory – is, in fact, our most potent weapon. Reinforcing its commitment strengthens our collective agency and resolve to respect human rights and fundamental freedoms.

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.
