The National Control Laboratory for Biological Products (NCL) Building.

There can be no compromise when it comes to the quality of medicines made available to the public.

The UFS-based National Control Laboratory for Biological Products (NCL) is a full member of the international WHO-National Control Laboratory Network for Biologicals and one of 12 laboratories worldwide contracted to perform vaccine testing for the World Health Organisation (WHO). The NCL is also the only vaccine-testing laboratory in the country that performs the final quality-control testing of all human vaccine batches marketed in South Africa on behalf of the South African Health Products Regulatory Authority (SAHPRA).

In its role as a vaccine-testing laboratory for the WHO, the NCL helps to ensure that the vaccines purchased through the WHO prequalification programme for international distribution to resource-limited countries, meet the high standards of quality, safety, and efficiency. 

International testing standards

The laboratory received the status of a pharmaceutical testing laboratory after the South African Accreditation System (SANAS) endorsed its quality-management systems as of a high standard according to the International Standards Organisation’s requirements.

With its international testing standards, the NCL must ensure that all its operations – from the way documents are compiled and stored, to the maintenance of equipment and infrastructure, as well as staff competency – are performed according to international guidelines.

The laboratory has all the quality systems in place to ensure high-quality test results. The certificate of Good Manufacturing Compliance received in 2019 indicates that laboratory testing is on the expected level for any pharmaceutical testing laboratory and manufacturer. This certification is very strict and means that the NCL complies with exceptionally strict standards for pharmaceutical labs anywhere in the world. The certification offers the South African Health Products Regulatory Authority, the WHO, and other national control laboratories around the world the confidence that the test results from the NCL can be trusted.

Licensed as pharmaceutical manufacturer

The laboratory is also licensed as a pharmaceutical manufacturer. Although the lab does not manufacture, it needs to comply with manufacturing standards. It is rare for a pharmaceutical testing laboratory (such as the NCL) outside of a manufacturing context to qualify for both certifications.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
