Food security and uncompromised food security are but two of the challenges facing the food industry.

When the national lockdown was announced by President Cyril Ramaphosa on 23 March 2020, it was indicated that South Africa’s food supply sector was to remain fully functional. This sector was one of the essential systems for livelihood and thus remained operational.

Prof Arno Hugo from the Department of Microbial, Biochemical and Food Biotechnology’s Food Science division at the University of the Free State (UFS) participated in a webinar, #MondayMotivation on Foodfocus with academics in the food industry, Profs Lise Korsten from the University of Pretoria (Department of Plant and Soil Sciences) and Pieter Gouws (Department of Food Science and Director of the Centre for Food Safety) from Stellenbosch University.

Foodfocus’ #MondayMotivation was presented by Linda Jackson, a Director at Food Focus SA. The platform provides information from recognised experts and services providers and offers training, consultation, and auditing to ensure that role players comply with the regulations set for the industry. 

A major focus of the webinar was on how well the food industry is performing under pressure during the lockdown initiated by government due to COVID-19. During the webinar, the academics also elaborated on their connection to the food industry. 

Uncompromised food safety

Prof Hugo thanked the food industry for their commitment in this difficult time and encouraged them to continue with the essential services that they provide. This includes the agricultural production sector, the food ingredients industry, the food processing industry, the food distribution industry, as well as the retail sector. 

“You are the frontline workers, our first line of defence, South Africans rely on you. You bring stability to the lives of every South African, providing us with safe and nutritious food. Due to your endeavours, our supermarket shelves are full and panic buying was therefore unnecessary. You work under difficult conditions at great personal risk, travelling to and from work. When working on factory floors, you had to adapt to even more strict hygiene protocols to prevent the spread of the virus,” he said. 

Prof Korsten said the food industry is in uncertain times. She emphasised the role that the industry is playing in food security – providing food of uncompromised safety. Many people are concerned about whether the food they purchase is still safe. 

“The circumstances under which the food industry is working are incredibly challenging,” said Prof Gouws. The Centre for Food Safety are working, among others, on building a food safety culture. “It is important to maintain consumer confidence in the safety of food as well as the availability of food. I believe the food industry is geared to ensure that the virus will not spread,” he added.

Is South Africa food secure?

Responding to the question of food security, Prof Hugo supported a statement by Agri SA Executive Director, Omri van Zyl, who said: “With the implementation of phase four lockdown, the entire South African agricultural value chain, with the exception of the local sale of tobacco and alcohol, was exempted. The export of wine and other agricultural products is now also allowed. Important agricultural services such as certification, inspection and quality control can continue.”

Referring to the opinion expressed by Paul Makhube, senior agricultural economist at FNB, Prof Hugo believes that one can stay positive about food security in the country. Makhube said: “South Africa expects its third largest maize harvest in history, while good harvests are also expected for soya peanuts and sunflower seed.”

“After the good rains, conditions are also more favourable for livestock production in some regions,” added Prof Hugo. 

Makhube continued: “Livestock auctions can continue under Level 4 restrictions under strict hygienic conditions. The large reduction in the fuel price will also result in lower input and harvesting costs for farmers and lower food distribution costs.”

Prof Hugo also endorses the positive sentiments about food security from Wandile Sihlobo, chief economist of the Agricultural Business Chamber of South Africa, who said: “South Africa will produce significantly more maize than the local consumption and are not much dependent on meat imports, especially beef.”

“Due to a strong and stable primary agricultural sector and an efficient and technologically advanced food processing industry, South African consumers are assured of the availability of enough safe and nutritious food. From a food security perspective, South Africa is in a much better position than many other countries in the world,” Prof Hugo believes. 

“A concern in our current situation, however, is household food security. Urgent interventions should be implemented in order for sufficient food supplies to reach the vulnerable and rising unemployed,” Prof Hugo reconed.

UFS adds to food science research

The UFS Division of Food Science is training undergraduate and postgraduate students for the food industry. Their research is mostly focused on chemical, microbiological and sensory quality, and stability of food. He added that the UFS has just completed the construction of a brand-new, well-equipped, and staffed Sensory Laboratory to deliver commercial sensory analysis services to the food industry.

Prof Hugo, whose field of specialisation is meat sciences and technology with a special interest in the lipid components of meat products, said the research he is working on includes how to change the diet of meat-producing animals to improve the health properties of fat tissue in meat. He is also investigating the use of natural preservatives and the effect of salt reduction on the quality and stability of meat products. This research group’s expertise in lipid chemistry also allows the department to conduct research on fats and oils and on the fat component of milk, dairy products, and plant foods.

He indicated that the department is working from home during lockdown to ensure that online teaching can take place, and that Food Science students at the UFS will be able to complete the 2020 Food Science curriculum.

Researchers international leaders in satellite tracking in the wildlife environment
2015-05-29

 

Ground-breaking research has attracted international media attention to Francois Deacon, lecturer and researcher in the Department Animal, Wildlife and Grassland Sciences at the UFS, and Prof Nico Smit, from the same department. They are the first researchers in the world to equip giraffes with GPS collars, and to conduct research on this initiative. Recently, they have been joined by Hennie Butler from the Department of Zoology as well as Free State Nature Conservation to further this research.

“Satellite tracking is proving to be extremely valuable in the wildlife environment. The unit is based on a mobile global two-way communication platform, utilising two-way data satellite communication, complete with GPS systems.

“It allows us to track animals day and night, while we monitor their movements remotely from the computer. These systems make possible the efficient control and monitoring of wildlife in all weather conditions and in near-to-real time. We can even communicate with the animals, calling up their positions or changing the tracking schedules.

“The satellite collar allows us to use the extremely accurate data to conduct research with the best technology available. The volume of data received allows us to publish the data in scientific journals and research-related articles.  

“Scientific institutions and the public sector have both shown great interest in satellite tracking, which opens up new ground for scientific research for this university. Data management can be done, using Africa Wildlife Tracking (AWT) equipment where we can access our data personally, store it, and make visual presentations. The AWT system and software architecture provide the researcher with asset tracking, GPS location reports, geo-fencing, highly-detailed custom mapping, history reports and playback, polling on demand, history plotting on maps, and a range of reporting types and functions,” Francois said.

Data can be analysed to determine home range, dispersal, or habitat preference for any specific species.

Francois has been involved in multiple research projects over the last 12 years on wildlife species and domesticated animals, including the collaring of species such as Black-backed Jackal, Caracal, African Wild Dog, Hyena, Lion, Cheetah, Cattle, Kudu, Giraffe, and Black Rhino: “Giraffe definitely being the most challenging of all,” he said.

In 2010, he started working on his PhD, entitled The spatial ecology, habitat preferences and diet selection of giraffe (Giraffa camelopardalis giraffa) in the Kalahari region of South Africa.

 

Since then, his work has resulted not only in more research work (supervising four Masters students) but also in a number of national and international projects. These include work in the:

  • Kalahari region (e.g. Khamab Nature Reserve and Kgalagadi Transfrontier Park)
  • Kuruman region (Collared 18 cattle to identify spatial patterns in relation to the qualities of vegetation and soil-types available. This project took place in collaboration with Born University in Germany)
  • Woodland Hills Wildlife Estate and Kolomella Iron Ore – ecological monitoring
  • A number of Free State nature reserves (e.g. Distribution of herbivores (kudu and giraffe) and predators (camera traps)

Francois is also involved with species breeding programmes and management (giraffe, buffalo, sable, roan, and rhino) in Korrannaberg, Rustenburg, Hertzogville, Douglas, and Bethlehem as well as animal and ecological monitoring in Kolomella and Beesthoek iron ore.

Besides the collaring of giraffes, Francois and his colleagues are involved in national projects, where they collect milk from lactating giraffes and DNA material, blood samples, and ecto/endo parasites from giraffes in Southern Africa.

With international projects, Francois is working to collect DNA material for the classification of the nine sub-species of giraffe in Africa. He is also involved in projects focusing on the spatial ecology and adaptation of giraffe in Uganda (Murchison Falls), and to save the last 30 giraffe in the DRC- Garamba National Park.

This project has attracted a good deal of international interest. In June 2014, a US film crew (freelancing for Discovery Channel) filmed a documentary on Francois’ research (trailer of documentary). Early in 2015, a second crew, filming for National Geographic, also visited Francois to document his work.
