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.

Department celebrates 50th anniversary

On 13 March the Department Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS) celebrated its 50th anniversary in a splendid fashion with a lecture entitled, The origin of life: Exactly how did life begin? as part of the Darwin commemorative lecture series, followed by a reunion of current and former staff members and postgraduate students of the department with a barbeque on the following day.

The proceedings were concluded on 14 March with a gala dinner in die Centenary Complex at the UFS attended by 153 staff members, post-graduate students (current and former) and other guests. During the dinner the guests were treated to a presentation of historical photos of the founding and development of the department. Currently the department is one of the largest departments in the Faculty of Natural and Agricultural Sciences in respect of the number of staff members and students as well as research outputs. This is the result of entrepreneurial actions to increase student numbers and research activities, as well as the merging with the smaller Department of Biochemistry in 1988 and more recently with the Department of Food Science in 2002. The department comprises 20 academics, 24 support staff and 65 postgraduate students. It also boasts 12 lecturers with ratings from the National Research Foundation (NRF), which include three academics with a B-rating, an indication of international recognition for their research. The department has the largest number of lecturers with an NRF-rating at the UFS. 

“It was interesting to learn during the reunion of the variety of professions occupied by former students of the department, i.e. at other tertiary educational institutions, the CSSIR, SAPPI, Sasol and a multitude of other industries, as well as at research institutions in the USA and Australia,” said Prof. James du Preez, Head of the Department.
