Opinion article by Sanet Madonsela, PhD Candidate in the Centre for Gender and Africa Studies, University of the Free State.
On the 24 February 2022 the world woke up to the news of Russia announcing its’ “special military operation” to “demilitarise” and “deNazify” Ukraine. This announcement was followed by a sophisticated, all-out attack by land and air. As Russia began its invasion, the rest of the world watched in anguish, contemplating the unavoidable international political and economic implications. 

There are competing views as to why Russia invaded Ukraine. Some argue that the attacks were based on Ukraine’s desire to join NATO, while others link the invasion to the Minsk agreements. The Minsk agreements are two treaties signed in 2014 and 2015 aimed at ending the war in Donbass. To provide a bit of context one needs to go back to 2014.

Resolution to recognise Donetsk and Lugansk

Moscow was angered that its candidate lost Ukraine’s presidential mantle in elections in 2014. This resulted in Donetsk and Luhansk announcing their autonomy from Kiev. In September of that year the government of Kiev and the separatist leaders agreed to a 12-point ceasefire called Minsk I. Despite the signing of the agreement, the fighting continued resulting in Russia, Ukraine and the
Special Monitoring Mission of the Organisation for Security and Co-operation in Europe (OSCE) signing Minsk II. The agreement called on Ukraine to control the state border, constitutional reform and decentralisation. Despite an election held in 2018 in the eastern regions, the US and the EU have refused to recognise the legitimacy of the vote, thus, violating the agreement. The OSCE has reported significant daily increases in ceasefire violations in the affected areas since February 2014. While the US is not a signatory, it has expressed the importance of implementing the agreement. Instead of accepting the existing agreement, Ukraine allegedly never implemented its provision thereby incensing Moscow as well as ethnic Russians in Ukraine. 

On 16 February 2022, the Russian parliament adopted a resolution requesting Putin to recognise Donetsk and Lugansk. This agreement was signed on 21 February 2022 and followed by a request to deploy armed forces. Inevitably the conflict dynamics have escalated. 

While some believe themselves to be immune to the conflict, economists warn that it will have far-reaching global consequences as armed conflict tends to disrupt supply chains and increase the price of food and gas. They predict a further increase in oil prices per barrel as Russia is the world’s largest natural gas exporter and the second largest exporter of crude oil. This is important as oil prices directly impact transportation, logistics, and air freights. On Thursday, 24 February, global oil prices past $105 per barrel warranting these predictions. In addition, Russia is the world’s largest supplier of palladium, a material used by automakers for catalytic converters and to clean car exhaust fumes, a delay which would affect auto production. It is worth noting that Ukraine is a major provider of wheat, corn, and barley. A lack of yellow maize, or even a slowdown in production, could result in an increase of meat prices. 

Exports and sanctions 

Combined, Russia and Ukraine export more than a third of the world’s wheat and 20% of its maize. They also account for 80% of global sunflower oil exports. They supply all major international buyers, as well as many emerging markets. In 2020, 90% of the African continent’s $4 billion agricultural imports from Russia were wheat and 6% sunflower oil. South Africa does not produce enough wheat and is heavily reliant on imports from these countries. It imported more than 30% of its wheat from these two countries over the past five years. 

Western states have announced a coordinated series of sanctions aimed at Russian elites; however, critics warn that they may be ineffective as the country’s economy is large enough to absorb even the most severe sanctions. Its central bank has more than $630 billon in foreign reserves and gold. Its sovereign wealth accounts for an additional $190 billion. Russian debt accounts for a mere 20% of its gross domestic product (GDP). 

The European Commission’s president, Ursula Von der Leyen, states that the bloc would target Russia’s energy sector by preventing European companies from providing Russia with the technology needed to upgrade its refineries. The US Department of Treasury has committed itself to prevent Russia’s state-owned Gazprom from raising money to fund its projects in the US. It is worth noting that Russia and Ukraine’s imports and exports to the US account for less than 1%, while Europe and Russia are interdependent. The EU needs Russian gas, while Russia needs the EU’s money. Some warn that the EU’s decision could be detrimental as it receives over a third of its natural gas from Russia. This is used for home heating and energy generation. These fears were intensified when the natural gas price in Europe increased by 62% on 24 February. It is believed that Russia has been preparing for economic isolation for years and that it could better absorb the sanctions than Europe’s ability to reduce its dependence on Russia’s oil, gas, and coal. Despite all these, Gazprom announced that its gas exports to Europe were continuing as normal. 

While the world watches with bated breath as the conflict rages there are some promising signs. Russian and Ukrainian delegates are currently meeting on the border with Belarus to start a dialogue and Ukraine’s President Volodymyr Zelenskyy has called on Israel to serve as a mediator between himself and Russian President Vladimir Putin. Let us pray that reason prevails.

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.
