“The government of the day should be based on the will of the people and must be led by people who deserve to lead us.” These were the words of Justice Mogoeng Mogoeng, the Chief Justice of the Republic of South Africa, during a prestige lecture delivered in the Faculty of Law on the Bloemfontein Campus of the University of the Free State (UFS) on 30 August 2019.

In addressing the topic of ‘Transformative Constitutionalism’, Chief Justice Mogoeng Mogoeng said this simply meant that the constitution was used as a tool to change or move a family, society, institution or the nation from an unacceptable to a more desirable position. He added that constitutionalism can be enhanced through ethical, courageous, and visionary leadership.

“There is a belief that judges should have nothing to do with matters of politics. I agree, but only to a certain extent. Judges are supposed to deal with political issues, as they interpret the constitution and the law. It is inescapable in a South African context. Some say that judges should only speak through their judgments. I've always said that our constitution is political in nature.”

“The preamble of our Constitution says this country belongs to all who live in it, but to what extent have we allowed our Constitution to achieve these objectives? A constitution does not implement itself. It takes people with a particular mindset and conviction. Transformation demands from the public to ensure that government is truly based on the will of the people,” he said.

According to the Chief Justice, South Africa needs strong and well-resourced institutions – including a strong judiciary. Institutions must be vigilant for any form of abuse of power and capture. Institutions cannot only be captured by external forces. They can be captured internally as well.

Another crucial element is education and the quality and condition of higher education at every level. “Our school system must allow the youth who are coming from high school to be able to adapt with ease when they get to university.”

“We need people who truly love their country to assume positions of power. Transformative constitutionalism is all about giving expression in a practical way. We should look at solutions for our country based on compromise that can bring us together as South Africans.”

He paid tribute to people such as former President Nelson Mandela, Mama Albertina Sisulu, and Adv Bram Fischer, who opted for the greater good of many, rather than personal satisfaction and gain. “South Africa belongs to all – not some – who live in it, united in our diversity. Are you prepared to serve the state? Do you love this nation? Go out there and pursue social justice. Don't buy things from thieves just because they are cheap. You are encouraging crime.”

“We can't continue this way and expect a different outcome. It is not too late; go out there and contribute towards building the South Africa that we can be proud of,” he concluded.

Hosted by Prof John Mubangizi, Dean of the UFS Faculty of Law, the prestige lecture was attended by approximately 800 guests, comprising senior members of the Supreme Court of Appeal, the Free State Division of the High Court, the university’s executive management, the Faculty of Law, staff members, students, and members of the public.

The Prestige Lecture Series was originally known as the Law Deans’ Prestige Lecture Series and was initiated by the late Prof Johan Henning, former Dean of the UFS Faculty of Law. The series started in 2011 as an initiative to encourage, develop, and expand academic discourse on topical jurisprudential issues and other related matters. Previous lectures were delivered by, among others, Prof Barry Rider from the University of Cambridge in the UK; Justice Richard Goldstone, formerly of the Constitutional Court of South Africa; former Deputy Chief Justice Dikgang Moseneke; and more recently, Judge President Dennis Davis.

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.
