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.

“The award serves to prove that my type of research is truly relevant.” These are the words of Dr Marieka Gryzenhout of the Department of Plant Sciences at the UFS, who received the T W Kambule NRF-NSTF Award as emerging researcher in June 2013.

The award from the National Research Foundation (NRF) and the National Science and Technology Forum (NSTF) gives recognition to her outstanding contribution to science, engineering, technology and innovation (SETI) in the country.

Dr Gryzenhout is also part of the Vice-Chancellor’s Prestige Scholar Programme.

“It was an honour to be chosen as a finalist, but to even win it? Die award indicates the importance of fungi and plant pathogens, and their presence in various biological systems and that it is important to identify and categorise significant plant pathogens and fungi to enable easier access for users of these names.”

Dr Gryzenhout was in the US on the evening of the awards ceremony, attending a workshop on the identification and research of another fungus group, Fusarium. “This group is extremely important, since it includes important plant pathogens, producers of toxins in food and feed, as well as animal and human pathogens, and it also plays important ecological roles.”

She attended the Kansas State University in Kansas and paid a visit to the Bacterial Foodborne Pathogens and Mycology Unit of the US Department of Agriculture in Illinois.

Dr Gryzenhout is also a finalist in the Women in Science Awards hosted by the Department of Science and Technology. The winner will be announced in August 2013. Prof Maryke Labuschagne and Rose Lekhooa are also nominees.
