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 celebrates establishment of a new department

The establishment of the Department of Genetics in the Faculty of Natural and Agricultural Sciences at the University of the Free State (FS) was recently celebrated on the Main Campus in Bloemfontein.

The department, which formed part of the Department of Plant Sciences, is the only of its kind in the country that conducts research in behavioural genetics. “With behavioural genetics we try to determine if certain human behaviour is hereditary or if it is as a result of the environment. Although this is the fastest growing field of specialty in the United States of America, it is still an unknown field in South Africa,” says Prof. Johan Spies, head of the Department of Genetics.

The other specialty fields of the department are forensic genetics and conservation genetics. “Forensic genetics looks at the compilation of the DNA of animals. Because of our academics’ expertise, the department is regularly requested by the South African Police Service to assist them with establishing the origin of animals – especially in the case of game poaching. We recently completed a research project on cheetahs where we had to establish if they were acquired illegally of part of the farmer’s game. The research showed that the cheetahs were part of the farmer’s own breed,” says Prof. Spies.

Another specialty field of the department is conservation genetics where the genetic variance of animals is researched. A lot of research is done on vervet monkeys to determine from which area in the country they originate. The study must be completed before the 3000 vervet monkeys currently in rehabilitation centres are set free. The behaviour of monkeys in rehabilitation is also being researched.

Prof. Spies says: “Student figures in Genetics show an annual increase of 8% per year for the past five years. The first group of master’s degree students in Genetics will start their studies next year.” The department is also regarded as a leader on Clivia research.
