Human Rights 18 March 2024

Echoing the words of Nelson Mandela, Prof Francis Petersen, the Vice-Chancellor and Principal of the University of the Free State (UFS), emphasised the profound significance of human rights. “To deny people their human rights is to challenge their very humanity,” he said during his opening address at the Human Rights Celebration held by the UFS Faculty of Law on 18 March 2024.

Acknowledging the pivotal role played by stalwarts such as Emeritus Justice Albie Sachs and Sir Sydney Kentridge, Prof Petersen delved into the strides made since the inception of South Africa’s contemporary constitution.

Underlining the university’s unwavering commitment to human rights, Prof Petersen added, “For universities, it remains critical that every aspect of academic life is viewed through the lens of human rights. The principle of equality lies at the centre of our purpose and operations.”

Furthermore, Prof Serges Kamga, Dean of the Faculty of Law, highlighted the institution’s vision encapsulated in Vision 130, striving to produce graduates who embody excellence and contribute to societal transformation.

Panel discussion: Sir Sydney Kentridge’s enduring legacy

Former Justice Zak Yacoob, renowned for his tenure at the Constitution Court of South Africa, paid tribute to Sir Sydney Kentridge in a panel discussion focusing on Kentridge’s contributions to human rights both nationally and internationally.

Reflecting on his personal experiences working alongside Sir Kentridge, Justice Yacoob highlighted the practical essence of human rights advocacy. He recounted Sir Kentridge’s seminal role in shaping the constitutional court’s early judgments, particularly emphasising the incorporation of human dignity into the constitutional framework.

Justice Yacoob’s insights shed light on the profound impact of Sir Kentridge’s jurisprudence on society, particularly in shaping notions of dignity, equality, and freedom. “The contribution he made was absolutely amazing. He wrote the first-ever judgement delivered by that court in April 1995. It was the first judgement that brought forth the issue of human dignity and its importance.”

Joining the discussion were esteemed panelists including Honourable Madam Justice Yvonne Mbatha and Dr Adri Du Plessis, who provided expert commentary on Sir Kentridge’s contributions to the legal fraternity. The discussion was moderated by Prof Elsabe Schoeman, Dean of the Faculty of Law at the University of Pretoria.

Honouring legal icons

Vanessa Rose September, Chair of the Albie Sachs Trust, presented books donated by the trust. The biography titled Arthur Chaskalson: A life dedicated to justice for all chronicles the life of Chaskalson, a towering figure in South Africa’s legal landscape.

Emeritus Constitutional Court Justice Albie Sachs delivered a thought-provoking lecture, pondering the question of whether there is cause for celebration on the 30th anniversary of human rights in South Africa.

With a rich history of activism and legal scholarship, Justice Sachs reflected on the evolution of South Africa’s judiciary and the enduring legacy of the Constitutional Court. Despite acknowledging prevailing challenges, Justice Sachs remained optimistic, citing the country’s constitutional framework as a beacon of hope and progress. “There’s lot to be angry about, there’s lots to complain about, there’s lots that has to be renounced, but there’s lots to celebrate. We’ve got a country, we’ve got a constitution, we’ve got rights, we’ve got instruments that we can use,” he said.

In conclusion, the Human Rights Celebration served as a poignant reminder of the ongoing struggle for dignity, equality, and justice, reaffirming the university’s steadfast commitment to upholding these fundamental principles in academia and beyond.

“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.
