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.

UFS hosts consortium to discuss broadening subcontinent’s food base

There is huge pressure on the agricultural industry in southern Africa to avert growing food insecurity. One of the ways to address this is to broaden the food base on the subcontinent via crop production. Climate change, urbanisation, population growth, pests and diseases continually hamper efforts to alleviate food insecurity. Furthermore, our dependence on a few staple crops such as maize, wheat, potatoes, and sunflower, serve to exacerbate food insecurity.  

Broadening the food base  
To address broadening the food base in southern Africa, scientists from the University of the Free State (UFS), the Durban University of Technology (DUT) and the Agricultural Research Council (ARC) have formed a Collaborative Consortium for the development of underutilised crops by focusing on certain indigenous and exotic crops. The Consortium met at the UFS this week for two days (6, 7 March 2017) to present and discuss their research results. The Principal Investigator of the Consortium, Prof Wijnand Swart of the Department of Plant Sciences in the Faculty of Natural and Agricultural Sciences, said awareness had risen for the need to rescue and improve the use of orphan crops that were up to now, for the most part, left aside by research, technological development, and marketing systems.  

"Many indigenous southern African
plant grains, vegetables and tubers
have the potential to provide a variety
of diets and broaden the household
food base.”

Traditional crops Generally referred to as alternative, traditional or niche crops, five crops are being targeted by the Consortium, namely, two grain legumes, (Bambara groundnut and cowpea), amaranthus (leaf vegetable), cactus pear or prickly pear and amadumbe (a potato-like tuber). Swart said these five crops would play an important role in addressing the food and agricultural challenges of the future. “Many indigenous southern African plant grains, vegetables and tubers have the potential to provide a variety of diets and broaden the household food base.” The potential of the many so-called underutilised crops lies not only in their hardiness and nutritional value but in their versatility of utilisation. "It may be that they contain nutrients that can be explored to meet the demand for functional foods," said Swart.

Scientific institutions working together
The Collaborative Consortium between the three scientific institutions is conducting multi-disciplinary research to develop crop value chains for the five underutilised crops mentioned above. The UFS and ARC are mainly involved in looking at production technologies for managing crop environments and genetic technologies for crop improvement. The DUT is focusing on innovative products development and market development.
