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.

A group of academics of Romania visited the Department of Medical Physics of the Faculty of Health Sciences at the University of the Free State (UFS) recently. Proff. Mihai Caramihai and Ana Chirvase are senior researchers of the Facultatea de Automatica & Calculatoare, Universitatea Politehnica Bucuresti who are working together with Prof. Charles Herbst and Dr William Rae of the UFS on the project MAmmary Malignancy Modelling using Artificial intelligence, ROmania South Africa, or Mamma Rosa. It is part of a larger local project aimed at implementing a computer-aided diagnosis programme (CAD), designed within the UFS's Department of Medical Physics, and which will take into account some of the South African requirements for computerised diagnostic radiology support. The National Research Foundation (NRF) provided travel funding and Prof. Herbst and Dr Rae visited Bucharest in November 2008 to collaborate with the Romanians. The visiting Romanian researchers were involved in a similar project where they were planning to model the changes in tumours as they grow and as they are treated. Dr Rae says there are many synergies between the two departments. The project has many aspects and there are several possibilities for related sub-projects. As a result the UFS has been able to attract three people to be involved in the project and they will do their Ph.Ds with the UFS. On the visit to Bloemfontein the roles of the researchers in the project were defined and the programme for the three-year collaboration was established. The stimulus created as a result of this collaboration has resulted in projects that will continue for at least the next four years.
