Histories of whites beyond whiteness the focus of inaugural lecture

Growing up in a small milling village on the Natal South Coast sugar belt from the mid-1960s to the early 1980s, Prof Neil Roos was exposed to poverty, privilege, liberalism, and racism. He carved out a promising academic career at the University of Natal, initially on white communists and the anomaly they represented in South African society - researching their histories in the Springbok Legion, a radical wartime kind of ‘trade union’ for soldiers.

During his doctoral work with the University of the North-West, he shifted his attention from the small number of whites who defied segregation and apartheid, to the large numbers who did not, and he began to engage with historical and comparative approaches to race. He was also interested in the sense of comradeship shown by white war veterans in the village where he lived, which included his own father, and used this interest to investigate the kinds of networks white veterans developed, as well as their role in movements like the war veterans’ Torch Commando and the Memorable Order of Tin Hats (MOTH). He used this history to show how white people were able simultaneously to ’oppose’ apartheid, yet accept its core premise of racial supremacy.

Possibility, dismay, and challenge

During his inaugural lecture on 14 February 2018 at the University of the Free State (UFS), Prof Roos addressed issues that delivered new insights under his fresh and rigorous research approach. “I intended to plot how histories of whites in South Africa have been written during several big historiographic moves, with sub-titles ‘possibility’, ‘dismay’ and ‘challenge’.” In the first section, ‘possibility’, he dealt with the vibrant 1980s-vintage South African social history, arguing that social histories of whites were at looked in a rather simplistic way. In ‘dismay’ he looked at the rise of cultural studies of whites in the new millennium which, he argued, tend to be self-absorbed, ahistorical and outside of any rigorous critique of society as a whole. In ‘challenge’ he proposed that contemporary political concerns, notably demands of the decolonisation movement, should inspire a new, activist, anti-racist history of race which draws on some of the strengths of the earlier social history movement as well as some of the techniques developed during the 1990s and the millennium to understand power, ideology and representation.

A new approach

Prof Roos proposes that histories of whites must more properly be histories of race. “This history must show the production of racial categories, reflect on the moral historiographies of being white, and the kinds of dehumanisation this demanded. It must also identify how and where whites transgressed, defied, opposed, or were simply docile. It must be emphatically anti-racist, and must absolutely avoid the possibility of apologia, of trying to gloss over or present with a human face histories of whites under colonialism, segregation and apartheid.” He also argued for an historical approach to present-day iterations of racial identity occurrences of racism, racial supremacy and racial violence.

“I intended to plot how histories of whites
in South Africa have been written during
several big historiographic moves.”

In arguing for the democratisation of studies about whites, Prof Roos argued that it is inconceivable that only whites write about histories of whites. He pointed out that black scholars bring fresh insights to the study of race, and of whites, and appealed for funding to be made available to black scholars pursuing these angles.  

Prof Roos, who is the author of Ordinary Springboks: White Servicemen and Social Justice in South Africa, 1939-1961, has held fellowships at the University of Chicago, the University of Technology Sydney, Harvard and Notre Dame. He is a professor in the International Studies Group and co-directs the Prestige Scholars’ Programme. He is the author of Whites in Apartheid Society, due for publication by Indiana University Press in 2018.

“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.
