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.

At the invitation of Dr Alice Brink of the Department of Chemistry, Prof John Helliwell, the 2015 Max Perutz Prize winner, and his wife, Dr Madeleine Helliwell, visited the University of the Free State (UFS).
The Helliwells, both chemists of note, took part in a series of lectures and exchanges on the Bloemfontein and Qwaqwa Campuses.
This visit from 9-19 November 2015 was the consequence of Dr Brink’s participation in the Vice-Chancellor’s Prestige Scholars Programme (PSP) initiative to encourage the broadening of the international footprint of the next generation of scholars in the academy.

Two year collaboration

Dr Brink and Prof Helliwell from Manchester University have a standing collaboration going back two years. Dr Brink, an NRF Thuthuka grant holder and a member of the PSP since 2013, has spent almost eight months in Manchester, collaborating with Prof Helliwell on her study of the successful interaction of rhenium tricarbonyl complexes with proteins determined via protein crystallography.
Their collaboration resulted from the close association of Prof Helliwell and Prof Andre Roodt from the UFS Department of Chemistry, both former presidents of the European Crystallographic Association.

Sharing academic expertise

Prof Helliwell, the 2014 American Crystallographic Association Patterson Award winner for his “pioneering contributions to the global development of the instrumentation, methods and applications of synchrotron radiation in macromolecular crystallography”, gave three lectures in the Department of Chemistry, two on the Boemfontein Campus, and the other on the Qwaqwa Campus on 13 November 2015.

Dr Helliwell, former co-editor of the Acta Crystallographica Section C: Crystal Structure Communications journal, consulted with postgraduate students from the Departments of Chemistry and Biochemistry.
