SASUF student members join Kovsie ACT in maintaining food garden beds on the Bloemfontein Campus.

There is something powerful about getting your hands in the soil, even more so when it is to help someone else. That is exactly what the group of South Africa–Sweden University Forum (SASUF) students did at the end of May, marking World Hunger Day by joining forces with Kovsie ACT to maintain and prepare food garden beds on the University of the Free State (UFS) Bloemfontein Campus.

The SASUF student team is helping with the upkeep of 40 vegetable beds in the food tunnels near Welwitschia Residence. These beds were established to supply fresh produce to students in need – a small effort with a big purpose.

Simba Matema, Research Assistant from the Office for International Affairs and SASUF Student Network National Coordinator, says this project is about more than planting vegetables. “We want to make sure that students who are struggling financially can benefit. But we also want to learn, to grow skills in agriculture and sustainability,” he explains.

 

A learning experience with real impact

Second-year student Lesego Moeleso says being involved in the garden is “a refreshing change of scenery” and a great way to “interact with students from different fields of study”. He adds: “We all want to help our fellow students who don’t have enough food.” 

Third-year UFS student Njabulo Sibeko agrees. “It’s a unique mix of academic enrichment, personal growth, and community engagement,” he says. “Even if the impact is small, it goes a long way. This project gives us a chance for hands-on learning and skills development, environmental sustainability and awareness, as well as social connections.”

Sibeko believes the garden also works as a “live experiment for environmental education”, teaching about “composting, water conservation, and organic farming”. He says, “Different vegetables have different nutrition, and if we can hold small workshops as to why we need to eat specific vegetables during different seasons, it will help teach us about the value they have for our body.”

Final-year Law student Shemsa Nzeyimana says her favourite part of being involved is “seeing the impact of our efforts” and “watching the garden grow and flourish”. “I love being part of a team that shares a common vision for creating positive change through sustainable practices,” she says. “And the fact that I get to be out of my comfort zone while building my social skills.”

 

Towards a sustainable solution

Nzeyimana hopes the garden “will become a hub for community engagement”, connecting students, staff, and locals while promoting sustainable food systems. “The garden directly addresses food security while also serving as a hands-on learning space for nutritional education and sustainable agriculture,” she adds. “By promoting sustainable gardening practices, the garden raises environmental awareness and encourages the campus community to think critically about food systems and their impact.”

At the UFS, where 59% of students report going hungry and 60% skip meals for financial reasons, the need is undeniable. Matema says by “giving students a role in the solution”, the stigma around food aid is reduced. “It becomes a shared project, not a handout.”

As Nzeyimana sums it up: “This garden can become a space for learning, connection, and hope – a place where change grows from the ground up.”

Besides Kovsie ACT, the initiative includes partners such as the Institute for Groundwater Studies, University Estates, the UFS Food Environment Office, and residences. External partners such as Tiger Brands, Sakata Seeds, and Kwaggafontein Nursery also support the project.

“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.
