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.

Project aims to boost science pass rate

The University of the Free State (UFS), in partnership with computer giant Hewlett Packard (HP), wants to boost the pass rate of its science students by using mobile technology.

The UFS is one of only 15 universities across Europe, the Middle East and Africa and the only university in South Africa to receive a grant from HP to promote mobile technology for teaching in higher education valued at USD$ 100,000 (or about R1 million). Altogether 80 universities from 28 countries applied for the grant.

“Last year HP invited a number of selected universities to submit proposals in which they had to explain how they are going to utilise mobile technologies in the redesign of a course that is presented at the university. The proposal of the Centre for Education Development (CED) at the UFS entitled “Understanding Physics through data logging” was accepted,” says Mr Cobus van Breda, researcher at CED and manager of the project.

According to Mr van Breda, students who do not meet the entrance requirements for the three-year B.Sc. programme have to enroll for the four-year curriculum with the first year actually preparing them for the three-year curriculum.

In order to increase the success rate of these students, the project envisages to enhance their understanding of science principles by utilising the advantages of personal computer (PC) tablet technology and other information and communication technologies (ICT) to support effective teaching and learning methodology.

“By using PC tablet technology in collaboration with data-logging software, a personal response system, the internet and other interactive ICT applications, an environment different from a traditional teaching milieu is created. This will consequently result in a different approach to addressing students’ learning issues,” says Mr van Breda.

The pilot project was launched during the fourth term of 2008 when 130 first-year B.Sc. students (of the four-year curriculum) did the practical component of the physics section of the Concepts in General Science (CGS) module by conducting experiments in a computerised laboratory, using data-logging software amongst other technology applications. “The pilot project delivered good results and students found the interactive application very helpful,” says Mr van Breda.

”The unique feature of the latter is the fact that real-life data can be collected with electronic sensors and instantly presented as computer graphs. It can then be analysed and interpreted immediately, thus more time can be devoted to actual Science principles and phenomena and less time on time-consuming data processing,” says Mr van Breda.

The CGS module can be seen as a prerequisite for further studies in physics at university level and in this regard it is of essence to keep looking for new models of learning and teaching which can result in student success. This year the theoretical and practical component of the physics section of the CGS programme will be done in an integrated manner.
