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.

New yeast named after Bloemfontein

A second living organism was named after Bloemfontein, adding to the fact that the University of the Free State (UFS) has the largest yeast collection in the Southern Hemisphere.

In an article in the highly acclaimed scientific journal, International Journal of Systematic and Evolutionary Microbiology, three lecturers from the Department of Microbial, Biochemical and Food Biotechnology, at the UFS, Dr Carlien Pohl, Prof. Martie Smit and Prof. Jacobus Albertyn, describe four new yeast species.
 
One of these species, isolated from pine needles from Bloemfontein, has been named after this city and will be known as Rhodotorula bloemfonteinensis. ‘Rhodo’ refers to the redness of these types of yeast. This makes this yeast only the second living organism to be named after Bloemfontein. The other is a mite (Pilogalumna bloemfonteinensis), which was described in 1972.
 
In short, yeast is a micro-organism that is part of the fungi family. Prof. Albertyn, “The most common of these are the bakers’ yeast, of which the bloemfonteinensis forms part.”
 
Among these four species they discovered, the Rhodotorula pini was also discovered on the Bloemfontein Campus of the UFS during December 1995.
 
“The UFS now has the largest yeast collection in the Southern Hemisphere. All over the world, science is busy researching the field of bio-diversity. This promotes the bio-diversity at the UFS,” Prof. Albertyn says.
