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.

Two of our academics contribute to a fascinating book

The planet has more species than ever before, but humans are responsible for the biggest mass extinction of all times. This is according to Prof. Jo van As, Head of the Department of Zoology and Entomology. He was speaking at the launch of the book The Story of Life & the Environment: An African Perspective.

The book was published by Random House Struik in July 2012 and is a sister publication of The Story of Earth & Life by Prof. Bruce Rubidge, which was published in 2005.

The Story of Life & the Environment: An African Perspective took five years to complete. Prof. Van As was the compiling author, with Prof. Johann du Preez, Head of Plant Sciences at our university, Prof. Leslie Brown of Unisa and Prof. Nico Smit of the North-West University as co-writers.

Prof. Van As said, “No other species has destroyed the earth as we have done. Biological diversity disappears at the rate of mass extinction. The effects of human activities on the biological diversity is bigger that the extinction of the dinosaurs.”

He, however, added that The Story of Life & the Environment: An African Perspective does not sketch a doomsday scenario. It has also a message of hope. Prof. Van As said it was good to see progress in conservation and care for the environment. Trans-frontier parks the size of some countries are a good example of work in this regard.

Mr Stephen Johnson, chairperson of the board of Random House Struik, said at the launch that the publishing house was proud to be associated with the impressive book. The publication will be a touchstone for thoughtful readers for a long time. It will also remain a general book for the public and learners on the topic. The content and design was done in such a way that the publication will be relevant to all audiences.

The Afrikaans version of the book, Die Verhaal van Lewe en die Omgewing, will be published soon.
