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.

Nano research at the UFS opens door to smart drugs
2011-06-27

 

Prof. Lodewyk Kock, outstanding professor in our Department of Microbial, Biochemical and Food Biotechnology

Novel antifungal, anticancer and anti-malaria drugs that have been identified in the research of Prof. Lodewyk Kock, outstanding professor in the Department of Microbial, Biochemical and Food Biotechnology at our university, will be disclosed later this year at major international conferences in Asia, Europe and the USA. Prof. Kock will be the keynote speaker at these conferences. 

His presentations will be based on the department’s discovery of yeast assays linked to a new nanotechnology for medicine. The assays were recently discovered by his group and can be applied in the development of novel antifungal, anticancer and anti-malaria drugs.
 
Prof. Kock’s focused research at the university, which now also includes his novel nanotechnology for Biology, began in 1982 in collaboration with Prof. Pieter van Wyk (Centre for Microscopy). He recently collaborated with Prof. Hendrik Swart (Department of Physics).
 
Prof. Kock says the development of novel anti-malaria drugs in particular is getting attention across the world due to the high rates of morbidity and mortality caused by the disease worldwide. Approximately 225 million people are infected annually and about a million (many in Africa) die each year. “Many potential smart drugs have been identified with this research and should now be tested further,” says Kock.
  
These new drugs will be disclosed during Prof. Kock’s keynote addresses at the International Conference and Exhibition on Pharmaceutical Regulatory Affairs in Baltimore, USA, from 6 to 7 September 2011, the Medichem 2011 in Beijing, China from 9 to 11 August 2011 and the XVI Congress of European Mycologists in Greece, from 19 to 23 September 2011.
