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 Riaan Luyt, professor in Chemistry and head of the Natural Sciences Programme at the Qwaqwa Campus of the University of the Free State, received an honorary medal from the Polymer Institute of the Slovak Academy of Sciences on Monday 29 September during a conference in the High Tatras mountains of Slovakia.

During the event Prof Luyt also presented a lecture entitled ‘Paraffin wax in polymer blends and composites: Is it worth investigating?’. In this lecture he gave an overview of the research that he and his group did over a period of 10 years in collaboration with scientists at this institute. The results of this research was published in eighteen international papers and one research book chapter.

Prof Luyt’s research at the Qwaqwa Campus involves polymer blends and composites, and he has already published 82 papers in international, peer reviewed journals, as well as two book chapters. At present his research group consists of nine doctoral and five master’s degree students, as well as a postdoctoral fellow. The postdoctoral fellow is from Nigeria, and one of the doctoral students is from Sudan.

Prof Luyt and his group collaborate formally internationally with groups in Kottayam (India), Modena (Italy), Budapest (Hungary) and Bratislava (Slovakia). He also collaborates informally with groups at the Universities of Pretoria and Stellenbosch, and with a group in Johor Bahru (Malaysia).

He previously received recognition for his research from the Faculty of Natural and Agricultural Sciences at the University of the Free State (Award for Outstanding Research in 2005) and from the Qwaqwa Campus of the UFS (Jubilee Medal and Certificate for Outstanding Research in 2007).
