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.

Crystals and crystallography form an integrated part of our daily lives, from bones and teeth, to medicines and viruses, new catalysts, jewellery, colour pigments, chocolates, analysing rocks on the moon and Mars, electronics, batteries, metal blades in airplane turbines, panels for solar energy and many more.

In spite of this, not many people know much about X-ray crystallography, although it is probably one of the greatest innovations of the 20th century, spanning the sciences. That is why this discipline is actively researched by a number of tertiary institutions around the globe as well as the Inorganic Chemistry Group of the Department of Chemistry at the University of the Free State (UFS).

Research by the Inorganic Chemistry Group includes:
•    clever design of model medicines to better detect cancer and study heart, bone and brain defects;
•    production of new compounds for making new and better automobile fuels and decrease carbon dioxide in the atmosphere;
•    generation and purification of new South African mineral resources for metals widely used in turbines which use wind energy.

A group of UFS students have received acknowledgement for their research at six international venues in the past few months.

Posters in Cameroon
Twelve postgraduate students, together with Prof André Roodt, Head of the Inorganic Chemistry division at the UFS, delivered three oral presentations, nine posters, one plenary and one keynote lecture abroad.

Four UFS students - Nina Morogoa, Pheello Nkoe, Alebel Bilay, and Mohammed Elmakki - who delivered posters at the First Pan African Conference on Crystallography in Dschang, Cameroon, received prizes for their presentations.

School and conference in Croatia

Students Orbett Alexander and Dumisani Kama were selected to attend the intense and demanding Third European Crystallographic School in Bôl, Croatia. Both Kama, Alexander and Prof Roodt gave oral presentations at the 24th Croatian-Slovenian Crystallographic Meeting at Brac Island, Croatia.

Kama, together with Dr Ferdi Groenewald, Dr Carla Pretorius and Pennie Mokolokolo, also attended the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The ESRF is a centre of excellence for fundamental and innovation-driven research. The storage ring at this laser facility can generate X-rays 100 billion times brighter than typical medical and laboratory X-ray sources.

Research in Switzerland

Kama and Mokolokolo also spent one month on research visits at the University of Zurich in Switzerland. Both Kama and Alexander were invited to present their research orally to the Institute of Inorganic Chemistry in Zurich, headed by Prof Roger Alberto.

In Basel, Switzerland, Dr Ferdi Groenewald, Dr Renier Koen, and Dr Truidie Venter all presented their research at the 30th European Crystallographic Meeting.

Prof Roodt said: “It is incredibly important that our postgraduate students get the chance to interact, discuss, and be taught by the best in the world and realise that hard work on basic and applied chemistry processes leads to broader recognition. The delegates to these international venues came from more than 60 countries and took note of our students work. With these young researchers, our future at the UFS and at Inorganic Chemistry is in good hands”.
