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.

Unconventional oil and gas extraction – study for Water Research Commission reveals possible impacts

The Centre for Environmental Management (CEM) at the University of the Free State (UFS) recently completed a three-year project for the Water Research Commission. The purpose was to develop an interactive vulnerability map and monitoring framework for unconventional oil and gas extraction (final report still to be published).

Due to the complexity of this field, a number of participants across different disciplines and universities were involved in this trans-disciplinary study. Contributors included the Departments of Sociology, Physics and Mathematical Statistics from the UFS, the University of Pretoria Natural Hazard Centre, Africa, as well as the Institute of Marine and Environmental Law from the University of Cape Town.

Unconventional oil and gas extraction, its related impacts and the management of this activity to ensure environmental protection, is a controversial issue in many countries worldwide. Since the extraction of oil and gas using unconventional techniques is an unprecedented activity in South Africa, the project focused on understanding this extraction process as well as hydraulic fracturing and identifying possible environmental and socio-economic impacts associated with this activity in the South African context. An understanding of the possible impacts could aid government during the development of policy aimed at protecting the environment.

The researchers subsequently identified indicators to develop an interactive vulnerability map for unconventional oil and gas in South Africa. The vulnerability map focuses on specific mapping themes, which include surface water, groundwater, vegetation, seismicity and socio-economics. In addition, the map provides information on the vulnerability of the specified mapping themes to unconventional gas extraction on a regional scale. This map is intended as a reconnaissance tool to inform decision-makers on areas where additional detail field work and assessments may be required. It can also be used during Environmental Impact Assessments and determining licensing conditions.

Lastly, a monitoring framework was developed, which describes monitoring requirements for specific entities – surface water, groundwater, vegetation, seismicity and socio-economics – for the different phases of unconventional oil and gas extraction. Such monitoring is an important part of environmental protection. It is especially important for South Africa to perform baseline monitoring before exploration starts to ensure that we will have reference conditions to identify what impact oil and gas extraction activities has on the biophysical and socio-economic environments.
