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.

FEMS Yeast Research, the top international journal in this field of research, recently announced their three "most read articles" of 2011, based on the number of downloads from their website. Of these three published papers, two are from the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS). They are:

The article with the title, The yeast Saccharomyces cerevisiae – the main character in beer brewing, was authored by Prof. Bettie Lodolo and Mr Martin Brooks (Brewing Consultant and Chief Brewer of the SAB Ltd. Brewing Centre of Excellence in Alrode, Johannesburg, respectively), Prof. Lodewyk Kock (Outstanding Professor in the UFS Department of Microbial, Biochemical and Food Biotechnology) and Prof. Barry Axcell (Global Chief Brewer, SABMiller, Sandton). Prof. Lodolo is also an Affiliated Professor in the UFS’s Department of Microbial, Biochemical and Food Biotechnology,

The authors of the second paper entitled The alcohol dehydrogenases of Saccharomyces cerevisiae: a comprehensive review, are Dr Olga de Smidt (Researcher at the Central University of Technology and a former Ph.D. student of the UFS Department of Microbial, Biochemical and Food Biotechnology); Prof. Koos Albertyn from the above department, and Prof. James du Preez Senior Professor and Head of this department.

The article by Lodolo et al. was also listed as one of the three most cited articles of 2010 published in this journal.
