In the build-up to Africa Day, I noticed – among others – the slogan ‘I love Africa’ flashing in neon colours that reminded me of music videos seen on MTV in the 1980s. The idea of Africa being loved not only by those living on the continent, but also by the rest of the world, had some moments in the same decade – with pop stars coming together, for example in USA for Africa and the UK version, Band Aid. Although these attempts might have warmed some hearts, it exposed the failure of this kind of sentimentality to contribute much to the continent. Can we think of how to love and engage with the continent in a different way?

Hannah Arendt, in her Thinking journal, contemplated the question, ‘why is it so difficult to love the world.' In response to a letter from her friend and mentor, Karl Jaspers in 1955, in which he wrote to her, “You bring with you shared memories of a lost past. You bring the wide world as it is today,” she wrote “Yes, I would like to bring the wide world to you this time. I’ve begun so late, really only in recent years, to truly love the world that I shall be able to do that now. Out of gratitude I want to call my book on political theories Amor Mundi” (1985: 264). Linked to the idea of loving the world in Arendt’s work, is also that of sharing the world with each other. Arendt famously accused Nazi Adolf Eichmann of refusing to share the world with others. For the purpose of Africa Day on 25 May, I revisited these notions of loving and sharing as reflected by Arendt. I raised the question – what does it mean to love Africa and to share the continent with others?

 For Arendt, the love of the world, and linked to it – the idea of solidarity – is something quite different from equality, care, and sentiment. Love of the world, for her, entails a critical engagement with the world. What could such a love mean in relation to Africa? 

In the prologue to The human condition (1958: 5), she underscores the importance of thought and her concern about thoughtlessness, which she describes as “the heedless recklessness or hopeless confusion or complacent repetition of ‘truths’ that have become trivial and empty”. She sets out that the central theme of the book is to focus on ‘what we are doing’ and that ‘the activity of thinking’ is left out of this work. In other works, Arendt turns to the importance of thinking and, in fact, commentators have noted an ongoing tension in her work between the life of action and the life of the mind. To love the world seems to include both a thorough engagement with what we are doing and a deep contemplation of what it is that we are doing. What has always struck me in her work, is the insistence on thinking and thinking anew each time, instead of merely following what is regarded as ‘truths’. Part of what it could mean to love Africa, is not to accept or repeat trivialities and not to become complacent, but to continuously search for new ways to understand and to respond.

A tension that accompanies the tension between a life of action and a life of thinking, is that between being with others and being alone. Human plurality is for Arendt ‘the basic condition of both action and speech’ (1958:175). Becoming part of the world is like ‘a second birth’ which takes place neither by ‘necessity’ nor by ‘utility’, but by taking ‘initiative’ (177). This birth or new beginning brings forth an ‘unexpectedness’ and ‘happens against the overwhelming odds of statistical laws and their probability’. Where the latter always ‘amounts to a certainty’, new beginnings ‘always appear in the guise of a miracle’ (178). It is by way of action that we become part of the world, share the world with others, and become entangled in the ‘web of relationships’ (181). Of course, for Arendt we always begin again, and the possibility for new ways of doing and forging new relationships is always there. 

Antjie Krog (2015:219) remembers Thabo Mbeki’s speech on the day the Constitution was adopted. “On an occasion such as this, we should, perhaps, start from the beginning. So, let me begin. I am an African. I owe my being to the hills and the valleys, the mountains and the glades, the rivers, the deserts, the trees, the flowers, the seas and the ever-changing seasons that define the face of our native land.” She praises Mbeki for considering the idea of ‘being ruled’ rather than ‘being a ruler’. She finds in his speech a “kind of radical relational enfoldedness with the land” that is vastly different from most discussions from all sides of the spectrum on land. To what extent are those of us living in Africa thinking differently and innovatively, for example about land, and about how we share it with others. How can we think anew about current discourses on the African Renaissance and also decolonisation?

Arendt is clear on the importance of solitude. She underscores the importance of thinking, and slow thinking, and obtaining distance from others, and from the world of action in order to do that. In her way, she was very wary of a certain kind of solidarity based on sentimentality. Engaged citizenship, for her, is always accompanied by a critical self-reflection. Arendt (2003) warned against the urge to act in haste without thinking; she warned against withering ‘under the weight of immediacy’. In a world and a continent with so many dire needs demanding attention and action, this does not mean that we should not act with urgency, but it underscores the importance of well-thought-out responses, of not falling back on old answers.

In short, loving Africa demands of us to engage critically, not to fall back on recipes and formulas, and not to follow rules blindly; it asks us to always begin again; to seek not only for new answers, but also for new questions.

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.
