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.

The launch of a unique conservation project
2011-06-06

 

Our Department of Animal, Wildlife and Grassland Sciences launched a very special pilot project at Woodland Hills Wildlife Estate in Bloemfontein on Friday 03 June 2011, which aims to eventually aid in the conservation and study of one of Africa’s most graceful animals.

The project aims to provide the scientific basis needed for making future decisions in the best interests of the giraffe in the Kgalagadi Transfrontier Park in the Northern Cape and involves collaring and monitoring the behaviour and movement of these animals via GPS.

Based on the public interest in the giraffe and the increased impact of the growing giraffe population on the vegetation in the area, SANParks has been considering the translocation of a number of Kgalagadi giraffe. Due to limited information regarding their adaptation success and potential impact on their new environment, thorough planning and subsequent monitoring of the species is required.

Mr Francois Deacon from our university decided to undertake a PhD study to address the existing challenges. This will be the first study of its kind, undertaken on giraffe.

He says he decided on this project because of his love for animals and conservation. “There are nine sub-species of giraffe and seven of these are already endangered. I want to involve people and make them aware of the plight of the animals and the need for conservation,” he said.

The project kicked off on Friday morning, with a group of students and curious nature-lovers tracking a herd of giraffe at Woodland Hills. The challenge laid in identifying one of the animals which could easily be collared with a GPS device, tranquilising it, and applying the device, without harming the animal.

After a young bull was identified, it was up to Dr Floris Coetzee, a veterinarian, to get close enough to the animal to tranquilise it, and to the group of students to catch it and hold it down. All this was done perfectly and the animal was fitted with its new collars. The collars were designed and made by Mr Martin Haupt, who gained extensive experience in the design of similar collars for other research studies.

Mr Deacon will spend the following two weeks personally monitoring the animal constantly, to ensure that the collars do not cause any discomfort or injury and to determine whether it should be removed or adapted.

It has taken Mr Deacon over a year to plan the collaring process and the associated study. He says the main challenges in the project are financial, since it will cost approximately R500 000 to run over five years.

Thus far he has been supported by Mr Pieter Malan of Woodland Hills, Mr Cas Kempff of Cas Kempff Consulting Engineers and Prof. Frans Swanepoel of the UFS’ Directorate of Research Development, all of whom have been benefactors of the project.
Information gathered from the pilot project will provide the data to assess how to best fit the collar onto the giraffe to ensure that the animal is comfortable and that the collar will last in the wild.  Scientific data will be generated and processed for use by the Woodland Hills Wildlife Estate management.

Should the pilot project be successful, between four and eight giraffe in the Kgalagadi will be tracked using the satellite GPS collars. The GPS collars will enable the constant recording of the location of individual giraffe for up to 2 years. This will allow control and monitoring of the animals in real-time.

The main benefits of the project include, amongst others, improved decision-making, informing tourism development, education and community involvement, improved sustainability and improved cross-border collaboration between South Africa and Botswana.
