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.

Prof Jeanet Conradie, professor in the Department of Chemistry at the University of the Free State (UFS), was the runner up in the senior category for Distinguished Women Researchers: Physical and Engineering Science in the Department of Science and Technology’s 2014 Women in Science Awards. With this award, female scientists and researchers are encouraged and rewarded, and also profiled as role models for younger women. 
 
Science and research, by which new concepts are discovered, is her great passion. Due to this keen interest in science, Prof Conradie studied a variety of subjects during her undergraduate years, providing her with a vast knowledge and the necessary background for her current main research interest, which is a combination of various scientific fields. Her PhD in Chemistry, as well as her strong background in Physics, Computer Science, Mathematics and Applied Maths, influenced her choice of research interest and expertise to gradually develop in the direction of computational chemistry, which is a beautiful combination of chemistry and physics. 
 
Today, Prof Conradie’s research expertise is in computational chemistry, using the super computer and appropriate software to simulate, understand and predict the behaviour of atoms and molecules in real life. The use of computational chemistry makes it possible to study chemical reactions and phenomena that are impossible or too dangerous to study experimentally. Her research team also performs experimental work in the laboratory to combine and compare with the computational analysis. Based on the results obtained, new materials with specific properties are developed. 
 
“We are very proud of Prof Conradie. This award is the result of 14 years of hard word, a lot of it after hours. We are fortunate to have someone like you as colleague who puts guidance to students and learners first in research, teaching and community service,” said Prof André Roodt, Head of the Department of Chemistry at the UFS. 
 
Prof Corli Witthuhn, Vice-Rector: Research said: “Prof Conradie serves as a role model for younger academic scholars in higher education through her motivation, productivity and drive. She also serves as an example of how female scientist can reach the top of their profession while juggling both professional and family responsibilities. This is well deserved recognition for her outstanding research achievements”
