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.

Short course in Applied Conservation Genetics developed at UFS

During discussions with stakeholders in Kenya in 2013, a need was identified for training in conservation genetics with an African emphasis. In answer, Prof Paul Grobler from the Department of Genetics developed a short course in Applied Conservation Genetics.

Some of the phenomena studied in this field include:
• hybridisation between species such as blue wildebeest and black wildebeest,
• wildlife poaching and
• potential inbreeding in small game-farm populations.

From the onset, the course has been developed as an international venture. To this end, Dr Frank Zachos from the Natural History Museum in Vienna, Austria, committed himself to the project. Dr Jamie Roberts from the Department of Fish and Wildlife Conservation at Virginia Tech University in the USA also came on board. Both pledged their time and expertise to the course – without any financial gain.

Subsequently, our Department of Genetics presented this short course at the National Zoological Gardens (NZG) in Pretoria earlier this year. The team of presenters included Prof Grobler, Dr Zachos and Dr Roberts. They were joined by Dr Desire Dalton from the Research Division of the NZG, who added valuable practical experience to the presentations.

The course assumes a degree of prior knowledge of population and molecular genetics. A strong emphasis is placed on practical applications. The programme includes a strong component of statistics and hands-on training in the many approaches and software used in population genetics.

The group that attended the course included a contingent from the Namibian Ministry of Environment and Tourism, Dutch postgraduate students currently working at the University of Johannesburg and delegates from across South Africa.

This successful meeting followed an experimental first round of the course presented in Nairobi during 2013, attended by representatives from Kenya, Malawi, Nigeria, Mexico and Belgium.
