The University of the Free State, through its Free State Centre for Human Rights, is pleased to present an online panel discussion titled, The Gaza crisis: How should South African universities engage with ‘pressing and urgent injustices’?

Following the killing of 1 143 people and the taking of 247 hostages by Hamas during an armed incursion in Israel on 7 October 2023, Israel mounted an invasion of the Gaza Strip. In the ensuing bombardment and ground offensive – which is continuing ten months after the Hamas attack – Israel armed forces have killed more than 38 000 people. Hamas’ killing and continued holding of hostages and Israel’s sustained offensive – described as an ‘unfolding genocide’ and a ‘massacre’ – confront universities with an enduring question: how to engage as institutions ‘with pressing and urgent injustices’?


Join us for an online panel discussion where pertinent questions emerging from the current crisis will be discussed. Should a university such as the University of the Free State formulate an institutional response to the Gaza crisis? If so, what form should it take? Is a statement, as has already emanated from several other South African universities, appropriate and sufficient? How to deal with current ties with Israeli universities, businesses, and individual academics? Can the UFS remain silent?

For South African universities, the Gaza crisis is a particularly apt lens through which to consider this question. Firstly, because Israel’s invasion of Gaza also manifested as a ‘scholasticide’: a large-scale destruction of schools, universities, and other places of learning in Gaza and the killing of Palestinian teachers and academics. Secondly, because of the strong historical and current links between South Africa, Palestine, and Israel: Israel’s past collaboration with the South African apartheid regime; the South African liberation movement’s enduring relationship with Palestinian liberation; and the many uncomfortable congruences between South Africa’s history of racially determined injustice and the current ethno-/racial social, political, and geographical segregation in Israel/Palestine.

Moderator

Prof Francis Petersen: Vice-Chancellor and Principal, UFS. 

 

Speakers
Prof Kistner has held teaching positions in Comparative Literature at Wits University, Modern European Languages at Unisa, and Philosophy at the University of Pretoria and is an extraordinary professor in the University of the Free State Department of Public Law. She is currently working on intersections between political philosophy, social theory, jurisprudence, and psychoanalytic theory.

Prof Nieftagodien is the NRF South African Research Chair in Local Histories and Present Realities and is the Head of the History Workshop at the University of the Witwatersrand, where he also lectures in the Department of History. He is the co-author – with Phil Bonner – of books on the history of Alexandra, Ekurhuleni, and Kathorus, and has also published books on the history of Orlando West and the Soweto uprising, and co-edited a book on the history of the ANC.

Prof Gillespie is a political and legal anthropologist with a research focus on abolition in South Africa, particularly concerned with the ways in which criminal legal processes become vectors for the continuation of apartheid relations. She joined the Department of Anthropology/Sociology at the University of the Western Cape in 2018, prior to which she worked for a decade at the University of the Witwatersrand (Wits). In 2008, she co-founded the Johannesburg Workshop in Theory and Criticism (JWTC), an experimental project tasked with recrafting the work of critical theory beyond the Global North. She writes and teaches about urbanism, violence, sexualities, race, and the praxis of social justice.

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.
