The Council of the University of the Free State (UFS) approved the appointment of Prof Philippe Burger as Dean of the Faculty of Economic and Management Sciences for a five-year term during its quarterly virtual meeting on 26 November 2021. 

He is Pro-Vice-Chancellor: Poverty, Inequality and Economic Development, as well as Vice-Dean (Strategic Projects) of the Faculty of Economic and Management Sciences, and Professor of Economics at the UFS. 

Extensive experience

Prof Burger was a 2016/17 Fulbright exchange scholar at the Center for Sustainable Development, Earth Institute, Columbia University in the United States, with Prof Jeffrey Sachs as his Fulbright host, where he wrote a book titled Getting it right: a new economy for South Africa. The book was launched, with presentations at the International Monetary Fund (IMF), World Bank, and RAND Corporation in Washington DC, among others. In addition, he is a member of the Fiscal Policy and Financial Markets Task Team of the Lancet Commission on COVID-19. Co-chaired by the Head of the IMF’s Department of Fiscal Affairs and a former Minister of Finance of Chile, the task team of 11 members comprises economists from across the world, including two Nobel prize winners. 

From September 2012 to October 2014, Prof Burger was President of the Economic Society of South Africa. His publications include three more books and numerous academic articles on fiscal rules and fiscal sustainability, public-private partnerships, and macroeconomic and economic development policy. Together with IMF staff, he co-authored two IMF working papers. In 2009, the IMF invited him to spend a month at the IMF as a visiting scholar in the Fiscal Affairs Department (FAD), researching public-private partnerships and the Global Financial Crisis. For two months each in 2007, 2010, and 2012, he was seconded to the Organisation for Economic Co-operation and Development (OECD) in Paris, France, to work on public-private partnerships and capital budgeting, while in October 2011 he joined an OECD mission to Indonesia to conduct a regulatory review of Indonesia. 

Prof Burger was a member of the Panel of Experts of the South African National Treasury, in which capacity he co-authored a 20-year review of South African fiscal policy since 1994. From 2013 to 2018, he was a member of the South African Statistics Council, which oversees the work of Statistics South Africa. From 1 February 2018 to 31 January 2019, he acted as dean of the Faculty of Economic and Management Sciences at the UFS, and from 2002 to 2019 he was Head of the UFS Department of Economics. 

“With more than 27 years of experience in the higher-education sector, Prof Burger will bring a wealth of expertise, extensive networks, and partnerships, nationally and abroad, to the Faculty of Economic and Management Sciences and the UFS. His experience in the positions held at the university, as well as his extensive knowledge and understanding of the South African and global economy, places him in good standing to lead the faculty to be a formidable and impactful academic force nationally and abroad,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor. 

“Prof Burger has the competencies required as dean of the Faculty of Economic and Management Sciences, leading it to exploit opportunities and deal with the challenges that the rapidly changing world presents to the UFS,” said Prof Petersen.  

Vision for the faculty

In response to his appointment, Prof Burger said, “I am humbled by this appointment and look forward to taking on this wonderful challenge. The faculty has a strong team of academics and administrative staff. With this team, I know we will create wonderful pathways for our students into the future and into the complex world of work. I also look forward to strengthening our research position and building the faculty as a nationally and internationally recognised research-strong faculty, as well as a faculty with a very strong Global South presence.”

Prof Burger succeeds the current Dean, Prof Hendri Kroukamp, who will be retiring at the end of February 2022.

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.
