On the morning of 23 February 2022, some of the entrance gates to the Bloemfontein Campus were blocked by groups of protesting students. The gates were cleared by members of Protection Services and traffic could continue to enter and exit the campus.

Sporadic disruption of classes occurred during the course of the day, with several students being arrested by the South African Police Service (SAPS) for disruption of classes, which is contravention of the interdict.

The disruptive behaviour stems from students’ unhappiness with the response to the memorandum handed to the university management by the Bloemfontein Campus Central Student Representative Council (CSRC) on 21 February 2022. Also on 21 February, a memorandum was handed to the management of the Qwaqwa Campus by the campus’ CSRC. The Qwaqwa Campus was temporarily closed yesterday, following violent protest action this week; the date for the reopening of the campus will be communicated in due course. 

Today’s disruptive behaviour demonstrated by the group of students on the Bloemfontein Campus is condemned and will not be tolerated.

During this week and on numerous occasions before that, the university management has been in extensive engagements with the CSRCs on both campuses; concessions were made where possible, as was demanded in the two memoranda. However, the responses given, and the concessions made by the university were not accepted by the student leadership of the Bloemfontein Campus CSCR in particular, with more demands being made.


Concessions from the beginning of 2022:

To ensure that students register successfully for the 2022 academic year, the UFS has granted a number of financial concessions to students since the beginning of the year. The financial support given was specifically intended to fast-track the registration process of students with outstanding debt, and those awaiting confirmation of funding from the National Student Financial Aid Scheme (NSFAS). 

These concessions included:

  • Allowing students who have previously registered for foundation programmes and those who have continued with mainstream programmes to register without the prerequisite of a first payment. The provision was granted to students who applied with the N+ rule and whose respective foundation programmes are included in the Department of Higher Education and Training-funded list.
  • Permitting students with outstanding debt of up to R25 000 and who await NSFAS funding to register provisionally.
  • The university also allowed conditional registration for first-time entering students, giving those who have applied for NSFAS funding until 28 February 2022 to finalise their registration. First-time entering students, both residential and non-residential, could register conditionally, provided that they pay an amount of R500.

Demands in the two memoranda received from the CSRCs on the Bloemfontein and Qwaqwa Campuses included matters such as private accommodation; emergency accommodation; catch-up plans for students who have not yet registered; a registration threshold increase to R30 000; NSFAS allowances; and the extension of registration for international students without study permits. The Bloemfontein Campus CSRC did not accept the university’s responses to the memorandum.

The university management will continue engaging with the SRC.

Safety measures in place:

The situation on the Bloemfontein Campus is closely monitored. Protection Services is on high alert and continues to work closely with the SAPS to ensure stability on the campus.

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.
