Dr Mutshidzi Mulondo, an academic in the Division of Public Health within the Faculty of Health Sciences, at the University of the Free State (UFS), has won a prestigious Global Health Award at the margins of the Global Health Summit in London, the UK.

Dr Mulondo, who is a Novartis Reimagining Healthcare Scholar and a Visiting Scholar at the Beaver College of Health Sciences at Appalachian State University, in the US, was a finalist in two categories: ‘Mental Health and Well-being’ and ‘Rising Star’. She won the Zenith Global Health Award under the category ‘Mental Health and Well-being’. The awards ceremony took place on 28 September and saw health professionals and academics gather in Europe for the auspicious occasion.

“This nomination and selection are an honour that bears testament to my dedication and commitment to SDG 3 (Good Health and Well-being). I hope this win serves as inspiration to young people, particularly to young women in academia and in the sciences,” says Dr Mulondo. The awards are an esteemed platform renowned for celebrating global recognition and excellence, fostering collaboration and innovation in the healthcare sector. They further serve as recognition for contributions made through education, research and/or technology and innovation.

Eco-anxiety

Dr Mulondo, who was invited to attend the summit for the first time, joined a panel of speakers on the session theme ‘mental health and climate change’ where she shared insights on eco-anxiety – the intersection of climate change and mental health which was coined by Albrecht as the chronic fear of environmental change.

Research by the McKinsey Health Institute, says Dr Mulondo, a fellow of the UFS Emerging Scholar Accelerator Programme (ESAP) and member of the UNESCO AG for Women in Science, indicates that more than 75% of young people are pessimistic about the future due to climate change. Most young people in the activism frontlines experience activist burn-out from consistent campaigning, while others experience eco-gaslighting from those who feel climate change is a non-issue. These negative emotions are further exacerbated by young people’s exposure to social media of constant images and conversations about environmental degradation due to climate change.

Pact for the future

Dr Mulondo flew to London from New York after participating in the 79th United Nations General Assembly’s Summit of the Future and Science Summit, as well as the New York Climate Week. She further provided insights into the adoption of the Pact for the Future which was adopted during the Summit of the Future. “With only 17% of the Sustainable Development Goals (SDGs) targets on track to be achieved by 2030, 18% stagnant and 17% regressed to pre-2015 when the goals were first adopted (SDG Report 2024), Mental Health still remains among 10 global health issues to track according to the World Health Organisation (WHO),” says Dr Mulondo.

“The Summit of the Future, which is regarded as a once-in-a-generation high-level event,” she continues, “was aimed at establishing a new global consensus to safeguard the present and future generations. Current challenges such as health pandemics, political unrest, and climatic changes were factored into discussions to keep apace with the changing world in the adoption of the Pact for the Future”.

Recommendations and mitigation efforts should focus on encouraging those experiencing eco-anxiety to focus on joining collective action efforts (i.e. campaigns to clean ocean and beach environments (etc,) so that they feel they are doing something towards saving the planet. “This will help alleviate the feelings of ‘hopelessness’ which some experience from not knowing what to do about the environmental degradation. Furthermore, intergenerational collaboration is necessary for young people to voice their concerns and innovative ideas on the issue, while the older generation listens and further shares their lived wisdom. Ultimately, collective support (Ubuntu) is what is needed as part of the mitigation efforts,” concludes Dr Mulondo.

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.
