A maxim says it is not enough to know that people have made mistakes; we need to understand why they made the mistakes if we hope to prevent them or others from making the same mistakes.

While South Africans are still trying to make sense of the many lofty promises made about measures to deal with the catastrophic energy crisis over the past four years, unsurprisingly, the restoration of energy security also dominated the 2023 State of the Nation Address (SONA).

Still, the reasons behind the failure of past intervention measures and progress with restructuring the state’s energy utility, Eskom, remain a mystery.

There is enough cause for concern over Eskom’s stance that an ageing fleet of coal-fired power stations that consistently break down is one of the reasons for load shedding. What happened to planning? No wonder the need to achieve quick success in resolving the energy crisis has placed a premium on maintaining citizens’ trust. As a result, the government proposed new initiatives to address the insecurity of the electricity supply by declaring a state of emergency to avert a complete blackout and appointing a new Minister of Electricity within the presidency to lead the government’s short-term energy crisis response. 

President Cyril Ramaphosa has already indicated that the criticism of the Minister of Electricity’s position is misguided. In other words, from the government’s perspective, the impact of its decisions does not matter. To South African citizens, however, it matters a great deal as they have borne the burden of load shedding and the rising cost of living. Above all, those who can cushion the blow of the energy crisis will want to see that the maximum value for public money is achieved.

The energy crisis has been the subject of fierce arguments over the past few years. So too, have deliberations on the government’s capability to deal with the crisis. And although the precise impact of the state of disaster, which began with immediate effect after its announcement in the SONA, cannot be determined at this stage, it is not premature to believe that the energy crisis will become a high-stake bidding game during the 2024 general elections. 

From the responses of the African National Congress (ANC) parliamentarians and alliance partners, one gets the sense that they sincerely wish there could have been a less dramatic option for the electricity minister, who has been touted to serve merely as a project manager.

Disastrous decisions are a recipe for catastrophic events

There has never been a time in South African history since 1994 that our presidents have not faced one scandal or another. After having temporarily thwarted the Phala Phala saga and emerging victorious as leader of the ANC at the 55th National Conference in December 2022, one would assume that President Ramaphosa would have assimilated the lessons from past events.

The post-SONA 2023 political landscape points to a challenging year for Ramaphosa. It is a truism that an organisation’s culture is determined by its leader. And since politics is not an exercise in objectivity, it is for this reason that several expected decisions by President Ramaphosa will determine how he will navigate between being regarded as a heroic figure and a victim of political persecution.

Objectively, it is hard not to agree with critics that a state of emergency will open the floodgates of collusion and corruption, which are distinct problems within South African public procurement. At this point, one wonders if this is not yet another gimmick to extend the patronage network of the presidency.

Another major decision facing President Ramaphosa is the much-anticipated cabinet reshuffle. Deputy President David Mabuza’s announcement that he resigned, only to be asked by the presidency to hang on, provides fascinating insight into how difficult it can become to exercise what some may regard as the mundane task of replacing cabinet ministers. And looking at the organisational footprint of the ANC, I reckon President Ramaphosa will avoid a situation where a cabinet reshuffle becomes another political hot potato from within his own organisation.

There is a fierce power war waging within the ANC. As a result, time will tell whether the president will be brave enough to replace poor-performing ministers instead of using proxies such as the new Minister of Energy. 

And to be clear – why we fail to confront underperforming ministers and public servants is a vexing question.

Indications are that there seems to be no aversion to brevity when it comes to political expediency, but to live up to the responsibility of accelerating structural reforms that significantly impact the country’s growth trajectory positively and reduce policy uncertainty. Continuing to routinely neglect these obligations is bound to create a more extensive trust gap between the government and citizens.

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.
