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 teams up with Department of Agriculture and donates latest farming technology to Oppermans

Emerging and commercial farmers of the Oppermans Community in the Northern Cape will now be able to monitor the salinity levels on their farms effectively for the first time.

This is as a result of a donation of the latest technology that measures the salinity of soil – the EM38 system – which the University of the Free State (UFS) is donating to the community.

The unique project was launched by the Department of Soil, Crop and Climate Sciences at the UFS and the Department of Agriculture in the Free State during an information day held at Jacobsdal recently.

The day was attended by members of the Oppermans Community and representatives of the UFS as well as the Department of Agriculture. Mr Sugar Ramakarane, Head of the Department of Agriculture in the Free State, did the welcoming and several academics from the UFS held discussions about various topics related to the salinity levels in soil.

Since the establishment of the Oppermans Community emerging farmers are now for the first time able to accurately monitor the salinity levels on their farms as well as that of irrigation schemes of commercial farms in the area.

“In a region such as the Northern Cape it is very important that the salinity level of soil is monitored properly. As water is administered to crops, salts accumulate in the soil because the roots leave most of the salts in the soil when it transpires. When the salinity of soil increases, the osmotic potential thereof can also increase, which can seriously damage the water intake of crops and can create loss in yield and income,” said Prof. Leon van Rensburg from the Department of Soil, Crop and Climate Sciences at the UFS and leader of the Oppermans Project.

To assist the farming community of Oppermans to apply precision farming and to measure the salinity level of soil more accurately the latest technology that measures salinity in soil – the EM38 – will be donated to the community. Although the system is used throughout the world, the UFS is the only tertiary institution in the country that owns the latest version of this system.

“We are also training two persons from the Oppermans Community as technicians that will monitor the use of the system. The advantage of the donation of the system for the university is that we can gather data that can be used for research purposes by our Master’s and Doctoral students. We also want to see if water-table heights can be measured with this system,” said Prof. Van Rensburg.

According to him the system has several advantages for the community’s emerging farmers. “For the first time the salinity level of soil can now be measured accurately, salt maps can be drawn up, we can advise farmers about the corrections that need to be made and salinity management plans can be compiled,” he said.

The system is very accurate as it takes measurements every 200 mm while it is pulled by a four-wheel motorbike. The readings provide the distribution of salts up to a soil depth of 1 500 mm. “In the past the measuring of salinity levels was time-consuming and the cost thereof was R90 for one sample. The new system is more cost-effective,” stated Prof. Van Rensburg.

The instruments will be handed over to the African Spirit Group of the Oppermans Community, who will then become the owners. The service to farmers will then be managed by an operational group consisting of people from the Oppermans Community, a postgraduate student who can compile salinity maps and Prof. Van Rensburg, who will act as project leader and advisor.

The system will also be made available to farmers at the Riet River and Vaalharts Schemes.
