Prof Robert Bragg recently participated in a live panel discussion with leaders from the food and beverage sector, debating the challenges facing the industry and sharing their lessons and solutions.

Prof Robert Bragg from the Department of Microbiology and Biochemistry at the University of the Free State formed part of a live panel discussion with leaders from the food and beverage sector, debating the challenges facing the industry and sharing their lessons and solutions.

The discussion, part of a week-long virtual event (19-23 April), was attended by more than 1 300 attendees representing 500 food manufacturers, retailers, ingredient companies, and laboratories from 83 countries.

The magazine, New Food, coordinated the initiative that focused on food integrity. Speaking with Prof Bragg at the session that centred around animal welfare, zoonotic disease, and antibiotics, were Catherine McLaughlin, Chair, Responsible Use of Medicines in Agriculture (RUMA); Vicky Bond, UK Managing Director, The Humane League; and Daniela Battaglia, Livestock Development Officer, Food and Agriculture Organization of the United Nations (FAO).

The rise of antibiotic resistance

James Russell, President of the British Veterinary Association (BVA), was the moderator of the discussion that also touched on the issues surrounding animal welfare; how animal welfare can impact meat quality; avoiding future zoonotic disease; the rise of antibiotic resistance; ethical considerations to be mindful of; and the use of pesticides and safety considerations.

Prof Bragg specifically talked about antibiotic resistance. “Mankind has major problems with antibiotics,” he said. 

He asked if animal agriculture can be sustained without the use of antibiotics and stated that it was necessary to look at alternatives. Possible solutions he suggested include improved vaccines, bacteriophages, and phage enzymes. He, however, believes that biosecurity will be the most effective alternative. 

Living in a post-antibiotic area

Disinfectants are one of the biosecurity measures taken to minimise the risk of infectious diseases. “But it is important to be aware of the fact that as resistance to antibiotics increases the resistance to disinfectants also increases,” said Prof Bragg. 

He continued: “An increase in the use of disinfectants increases the resistance to disinfectants. This is also evident in humans, especially now during the COVID-19 pandemic. Much of these disinfectants are also of poor quality,” he said. 

According to Prof Bragg, we are living in a post-antibiotic era. “Although food standards are higher in developed countries such as in Europe – where people can pay more for poultry that were fed diets with reduced antibiotics, it is important to keep in mind that people cannot pay the same for poultry in developing countries. These countries often import poultry from countries where the food standards are not that high and where birds were treated to diets containing more antibiotics. A large supplier of poultry in Africa is small-scale farmers, who also feed their birds food containing higher levels of antibiotics.” 

“We need to look at the antibiotic problem as a global problem; a concern that will be with us for a while,” said Prof Bragg.

One solution provided by the group was for mankind to reduce its meat intake and moving to a more plant-based diet. This will have a significant effect on animal welfare as well as reducing the demand for antibiotics.

First doctorate in Thoracic Surgery in Africa awarded
2009-05-12

The University of the Free State (UFS) has become the first university in Africa to award a Ph.D. degree in Thoracic Surgery. The degree was conferred on Prof. Anthony Linegar from the university’s Department of Cardiothoracic Surgery during its recent graduation ceremony.

Thoracic surgery is a challenging subspecialty of cardiothoracic surgery. It began in South Africa in the 1940s and is a broad medico-surgical specialist discipline that involves the diagnosis, operative and peri-operative treatment of acquired and congenital non-cardiac ailments of the chest.

Prof. Linegar became the first academic to conduct a mixed methods analysis of this surgical specialty, which included a systematic review of all the research done in this field in South Africa. The title of his thesis is A Model for the Development of Thoracic Surgery in Central South Africa. The research was based on the hypothesis of a performance gap between the burden of disease in the community and the actual service provision. It makes use of systems theory and project management concepts to develop a model aimed at the development of thoracic surgery.

The research proved that there is a significant under provision of clinical services in thoracic surgery. This was quantified to a factor of 20 times less than should be the case, in diseases such as lung and oesophagus cancer. According to Prof. Linegar, there are multiple reasons for this. Listed amongst these reasons is the fact that thoracic surgery is not part of the undergraduate education in medical training. There tends to be a low level of awareness amongst clinicians as to what the thoracic surgeon offers their patients. The diagnostic and referral patterns in primary and secondary health facilities, where diseases must be picked up and referred early, are not functioning well in this regard. In addition, relatively few cardiothoracic surgeons express an interest in thoracic surgery.

Prof. Linegar’s model is named the ATLAS Mode, which is an acronym for the Advancement of Thoracic Surgery through Analysis and Strategic Planning. It includes the raising of awareness of the role of the specialist thoracic surgeon in the treatment of patients with thoracic diseases as part of the solution to the problem. Furthermore, it aims to develop an accessible and sustainable specialist service that adequately provides for the needs of the community, and that is appropriately represented in health administration circles.

His promoters were Prof. Gert van Zyl, Head of the School of Medicine at the UFS, Prof. Peter Goldstraw, from the Imperial College of London, United Kingdom (UK) and Prof. Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS.

Prof. Linegar has been with the UFS since 2004, is a graduate from Stellenbosch University in 1984 and completed his postgraduate training in Cardiothoracic Surgery at the University of Cape Town. He was granted a Fellowship in Thoracic Surgery at the Royal Brompton Hospital in London, UK and has since held consultant positions at the UFS, Stellenbosch University and in private practice. He has been involved in registrar training since returning from the UK in 1994 and has extensive experience in intensive care medicine. He has published widely, has presented papers at many international conferences, has been invited as a speaker on many occasions and has won awards for best presentation on three occasions.
