South Africans are sick and tired of corruption. They are angry, frustrated and despondent. And they have every reason to be. South Africa has many problems: crime, unemployment, poverty, gender-based violence, inequality, low economic growth and now – in common with many other countries – COVID-19. The list goes on and on. What makes corruption the biggest threat among all these is that it cuts across all of them and impacts on their gravity in different ways. 

The South African Constitution envisages a society based on democratic values, social justice and fundamental human rights. The way things are going, that society is never likely to happen. That is because corruption has been, and continues to be, the greatest threat to any possibility of realising that constitutional dream. In South Africa, like everywhere else where corruption is rampant, it occurs both in the public and private sectors, where it affects democracy and human rights by deteriorating institutions and diminishing public trust in government. It impairs the ability of government to fulfil its obligations and ensure accountability in the delivery of economic and social services like healthcare, education, clean water, housing, and social security. This is because corruption diverts funds into private pockets – which impedes delivery of services – thereby perpetuating poverty, inequality, injustice and unfairness. The problem is aggravated when government is the main culprit. “Government” here, of course, refers to the dictionary meaning of the term, namely, “the group of people with the authority to govern a country or state”.

Corruption existed in ancient Egypt, China and Greece

There are those who argue that corruption is as old as mankind and, therefore, it is here to stay. Indeed, corruption is known to have existed in ancient Egypt, ancient China and ancient Greece. In Robert Bolt’s 16th Century play A Man for All Seasons, Richard Rich’s opening remark is “But every man has his price.” In the 1836 play The Government Inspector, Nikolai Gogol cleverly satirised the human greed, stupidity and extensive political corruption in Imperial Russia at the time. And in a recent article in The Conversation (28 August 2020), Steven Friedman wonders why South Africans express shock at corruption when “it is perhaps the country’s oldest tradition.” He locates the advent of corruption in South Africa at the arrival of Jan van Riebeeck in 1652, through to the ensuing colonialism and apartheid. He argues that in reality, “corruption has been a constant feature of South African political life for much of the past 350 years. It is deeply embedded and it will take a concerted effort, over years, not days, to defeat it”. 

Agreed, but does it have to be that way? At the time of Jan van Riebeeck and during the 350 years of colonialism and apartheid, we did not have the legal framework that we have now. Here is a brief overview of that framework.

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.
