This year’s Freedom Day marks an important milestone in the history of South Africa. It will be 27 years since the first non-racial elections were held in the country, a figure that equals the number of years Nelson Mandela spent in prison.

If equating Mandela with the freedom we enjoy today is not already disingenuous enough, we sunk even lower by assuming that we are close to achieving the civil liberties he embodied. You do not have to go further than read the daily media headlines to understand the extent of the onslaught on the pillars of democracy. That this onslaught comes from political leaders is one of the main reasons why most South Africans are disillusioned with politics, democracy and social issues.

Anarchy wreaking havoc in weak societies

Sociology taught me about the relevance of institutions to a social structure: they control human conduct by setting up predefined behaviour patterns. For example, throughout history anarchy has wreaked havoc in settings where organisations are weak, fragmented, and the citizenry is inactive. Similarly, while peace, unity, and the preservation and the restoration of human dignity are the hallmarks of Freedom Day celebrations, we have become a nation increasingly influenced by symbolic politics and the politics of offence.

It would be hard to find a better example of a significant threat to the pillars of democracy than the widespread onslaught on the judiciary. At the heart of the broader political, legal, and moral issues confronting SA today is how the right of all to equal respect and equal protection under the law has been compromised. Casting doubt about the independence of the judiciary conceals the motivations that most endanger the principles of freedom and equality.

My stance is not aimed at muting the expression of unpopular opinions – a basic tenet of democracy. However, we need to be mindful of events that have and will become powerfully symbolic in altering the nation’s social fabric.

Freedom under attack by populist politics

Any societal change requires some form of flexibility. No doubt, the first decade of democracy was accompanied by hope and the euphoria of the Rainbow Nation. This period demonstrated how different racial groups could live together in harmony, play together, and attend the same school without being required to forsake values they hold dear. This period was punctured by notions of active citizenship and the promotion of democratic cooperation that is based on the acceptance of universal human rights and the rule of law and values of diversity.

While millions of people elsewhere in the world have been forced to flee hunger, war, terrorism, and emboldened autocrats in their countries of birth, the euphoric wave of the Mandela years has, unwittingly and dramatically, worn off during the past decade in South Africa. This turn of events is linked to populist politics that seriously compromise democratic institutions in the country.

In my opinion, there are no heroes in situations like these.

In a country characterised by rampant corruption, violent crime, gender-based violence, human trafficking, racial intolerance, and teenage drug abuse, are politicians the only ones to be blamed for the threats to democracy?

Conquering immorality and safeguarding our freedom

Despite all the challenges we face as a country, we remain a remarkably resilient nation, as is widely acknowledged. This resilience is echoed by how we have navigated our way around a highly divisive and intolerant society to embrace and celebrate our rich and vibrant cultural heritage.

Nevertheless, we have become complacent. We have been vocal against any narrative aimed at restricting our legal, religious, human, civil, economic and political rights. Yet, partly due to our collective inaction, we have failed to use the means to provide a compelling counter-narrative of resistance to the manipulation of state institutions and broader immorality permeating society. This inaction affects the lives and livelihoods of millions of those who do not have the organisational capacity and means to advocate for the causes that affect them.

Let us use this year’s historic Freedom Day celebrations to demonstrate our firm resolve to protect the critical pillars of democracy from further exploitation. This kind of collective responsibility is what South Africa has always been about. Only when our government at all levels, the private sector, and concerned citizens across the country begin a critical partnership and commitment to maintain our democratic institutions and processes that our past losses as a nation become gains and defeats become triumphs.

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.
