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.

UFS academic appointed to prestigious academy (ASSAf)
2014-10-07

Another academic of the University of the Free State (UFS), Prof Jeanet Conradie, professor in Chemistry, was invited as newly elected member of the Academy of Science of South Africa (ASSAf).Science and research, by which new concepts are discovered, is her great passion.

Her PhD degree in Chemistry, together with also a strong background in Physics, Computer Science, Mathematics and Applied Mathematics, influenced Prof Conradie’s choice of research interest and expertise to develop gradually in the direction of computational chemistry, which is a beautiful combination of chemistry and physics.

Computational chemistry uses quantum physical principles and mathematical methods to solve chemistry problems via high-performance computerised calculations. Results obtained can be used to predict and understand the behaviour of atoms and molecules in the real world. Chemical reactions and phenomena that are impossible or too dangerous to study experimentally, can also be studied by computational chemistry. Her research team also does experimental laboratory work to combine and compare with the computational analysis. Based on these results, new materials with specific properties are developed.

The Academy of Science of South Africa (ASSAf) aspires to be the apex organisation for science and scholarship in South Africa, recognised and connected both nationally and internationally. Through its membership which represents the collective voice of the most active scholars in all fields of scholarly enquiry, ASSAf aims to generate evidence-based solutions to national problems.

Prof Corli Witthuhn: Vice-Rector: Research at the UFS said: “The UFS is very proud of Prof Conradie, who is also the first female professor in the Department of Chemistry.  Jeanet is a highly productive researcher publishing in high-impact journals.  She has extensive international networks and collaborations, increasing the impact of her work even more.  We are currently awaiting the outcome of her application for NRF rating and believe that she will receive an excellent rating.”
