Dr Lucia Meko believes that face-to-face engagement helps students become more empathetic, culturally aware health professionals.

In South Africa, the streets often tell stories of contrasts where wealth and poverty, tradition and modernity, and diverse cultures meet at the same intersection. It is a place where neighbours may speak different languages, worship in different ways, and sit down to very different meals. These everyday differences do not just influence how people live – they shape what ends up on their plates.

According to Dr Lucia Meko, Senior Lecturer and Head of the Department of Nutrition and Dietetics at the University of the Free State (UFS), dietitians play an important role in such a diverse landscape. “Their mission is to empower individuals and communities to make informed, healthy food choices that support long-term well-being. According to the Health Professions Council of South Africa (HPCSA), dietitians are trained to provide personalised nutrition counselling aimed at preventing and managing diet-related diseases,” she says.

“This means that whether someone is dealing with diabetes, high blood pressure, or simply trying to improve their eating habits, a dietitian can offer guidance tailored to their unique needs and circumstances.”

However, Dr Meko believes that while theory is important, many students only truly understand the reality of their future clients when they experience it first-hand. At the UFS, students do not have to wait until the end of their degrees to gain this insight. Community service learning begins in their very first year.

This approach immerses students in the communities they will eventually serve, offering a practical education that goes beyond textbooks. By working directly with communities, students gain a deeper appreciation of the challenges individuals face in making healthy food choices,” she says.

“These experiences help shape well-rounded professionals who are not only knowledgeable but also empathetic and culturally aware,” adds Dr Meko.

Unlike traditional volunteering, this is structured learning with clear outcomes. Students apply classroom theory to real-world issues while simultaneously giving back. Through this process, students develop critical thinking, cultural competence, and the ability to communicate health information in ways that are relevant and respectful,” she explains.

 

What really happens on the ground

To understand what this looks like in practice, Dr Meko points to a research study conducted by the department. It examines the experiences of fourth-year students during a Community Nutrition Module internship. This internship is one of eight work-integrated learning (WIL) components in the module.

In this particular placement, students work in Ward 51 in Mangaung, visiting homes and engaging directly with residents. During each visit, they profile the community member’s demographics, measure nutritional status (using weight and height), and assess dietary patterns. Afterward, they offer tailored dietary counselling.

Beyond individual visits, students also explore the broader food environment: visiting supermarkets, vegetable gardens, early childhood centres, and street vendors all form part of their learning.

Importantly, this programme is not one-sided. Feedback from both students and community members is gathered to improve the experience and assess its impact.

So far, early findings are promising. Students not only learned; they were transformed. Interestingly, students mostly showed appreciation for their own privileges in comparison to the disadvantaged communities they visited,” says Dr Meko. One student reflected: “It humbled me and made me very grateful for all that I have, because I think we really lose sight of that sometimes.”

After a township tour, another student admitted: This was very insightful, as we often have stereotypes about the way people live and what people eat, simply because of where they live.”

In a cooking activity, students were challenged to apply dietary guidelines in real kitchens. The outcome? A deeper understanding of the barriers faced by many. “Dietetic guidelines we have given to some patients were really put into perspective, as cooking with less salt is not as easy as we think,” says Dr Meko, quoting student feedback.

Some even used what they learned in other placements. One student took a simple grocery list she developed during her internship to the hospital setting: “It is the most practical way to influence someone to shop differently.”

Others were inspired to continue working in food access. “I was impressed with the size of the vegetable gardens and was also inspired to be part of projects like these in the future,” shared another student.

Perhaps one of the most powerful observations came from a student who said: “I feel empowered but also sad to see that this is how most of the country is living and that we can make a difference, no matter how small.”

 

A lasting impact for both student and community

For Dr Meko, this is exactly what service learning should achieve. “While lectures and textbooks can teach the theory behind intercultural competence, it’s the face-to-face interactions – listening to people’s stories, understanding their struggles, and working alongside them – that truly bring those lessons to life.”

She adds that this kind of learning also builds stronger, more respectful relationships between the university and the communities it serves. “It fosters partnerships built on mutual respect, shared goals, and the exchange of knowledge and resources – locally and beyond.”

Community service learning is not just a tick-box exercise. In the UFS Department of Nutrition and Dietetics, it is a meaningful bridge between knowledge and empathy, between theory and reality, and – most importantly – between future dietitians and the people whose lives they hope to improve.

“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.
