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.

Africa the birthplace of mathematics, says Prof Atangana

Prof Abdon Atangana from the Institute for Groundwater Studies at the University of the Free State recently received the African Award of Applied Mathematics during the International conference "African’s Days of Applied Mathematics" that was held in Errachidia, Morocco. Prof Atangana delivered the opening speech with the title "Africa was a temple of knowledge before: What happened?” The focus of the conference was to offer a forum for the promotion of mathematics and its applications in African countries.

When Europeans first came to Africa, they considered the architecture to be disorganised and thus primitive. It never occurred to them that Africans might have been using a form of mathematics that they hadn’t even discovered yet.

Africa is home to the world’s earliest known use of measuring and calculation. Thousands of years ago Africans were using numerals, algebra and geometry in daily life. “Our continent is the birthplace of both basic and advanced mathematics,” said Prof Atangana. 

Africa attracted a series of immigrants who spread knowledge from this continent to the rest of the world.

Measuring and counting
In one of his examples of African mathematics knowledge Prof Atangana referred to the oldest mathematical instrument as the Lebombo bone, a baboon fibula used as a measuring instrument, which was named after the Lebombo Mountains of Swaziland. The world’s oldest evidence of advanced mathematics was also a baboon fibula that was discovered in present-day Democratic Republic of Congo.

Another example he used is the manuscripts in the libraries of the Sankoré University, one of the world’s oldest tertiary institutions. This university in Timbuktu, Mali, is full of manuscripts mainly written in Ajami in the 1200s AD. “When Europeans and Western Asians began visiting and colonising Mali between the 1300s and 1800s, Malians hid the manuscripts in basements, attics and underground, fearing destruction or theft by foreigners. This was certainly a good idea, given the Europeans' history of destroying texts in Kemet and other areas of the continent. Many of the scripts were mathematical and astronomical in nature. In recent years, as many as 700 000 scripts have been rediscovered and attest to the continuous knowledge of advanced mathematics and science in Africa well before European colonisation. 

Fractal geometry

“One of Africa’s major achievements was the advanced knowledge of fractal geometry. This knowledge is found in a wide aspect of Africa life: from art, social design structures, architecture, to games, trade and divination systems. 

“The binary numeral system was also widely known through Africa before it was known throughout much of the world. There is a theory that it could have influenced Western geometry, which led to the development of digital computers,” he said. 

“Can Africa rise again?” Prof Atangana believes it can.

He concluded with a plea to fellow African researchers to do research that will build towards a new Africa.
