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.

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry

Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data

Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.


Technology such as drones offers unique
opportunities to study animals like giraffes.



Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
