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.

Like Idols for scientists
2014-04-10

Kovsie student and scientist Karabelo Moloantoa recently represented the Free State in the South African finals of the FameLab competition during the Sci-Fest in Grahamstown.

Karabelo is a 24-year-old student doing his master’s in Biotechnology. He completed his Bachelor’s degree in Medical Microbiology, as well as his Honours degree in Biochemistry at Kovsies. His research is focused on Bioremediation of mine waste waters.

“FameLab is like the scientists Idols taking place annually,” says Karabelo.

“In the competition we are given three minutes to explain a science aspect to a non-science audience. There are 25 countries that participate. South Africa is the only African country participating.”

“I was called by one of my lecturers an hour before the local competition took place at the National Museum in Bloemfontein. I was actually still tired from playing volleyball the night before,” he explains. “I was unprepared and without slides, but I did my presentation.”

This was the first year Karabelo entered FameLab and although he was somewhat unprepared for the local competition in Bloemfontein, he was nominated to represent the Free State in Grahamstown at the Sci-Fest event. From the 18 semifinalists, Karabelo qualified to go the finals where the 9 finalists were competing to represent South Africa in the United Kingdom for the international finals.

“I did not win the UK trip, but I made it to the finals, which is an achievement as half of the semi-finalists could not make it to the finals,” says Karabelo.

“I feel like I have done well to represent the university and the province as a whole. It was amazing to speak in front of more than 800 people, delivering my presentation. I learnt a lot and improved my skills of communicating scientific aspects. I will definitely enter again next year.”
