Listeria and the controlling cavalry on the shop floor

The food safety scenario in South Africa has, by virtue of the sad consequences of the listeria outbreak, been given a violent shake-up. While much of the attention has been focussed on the companies potentially implicated it may also be helpful to consider the role played by the unseen cavalry which safeguards against such occurrences.

These role players are myriad in any production system and range from senior management to the person cleaning the floor. Every single employee in any food production and distribution facility has a role to play in ensuring the safety chain. More particularly, a critical part of these teams are the food scientists and technologists that we train here at CPUT and are employed by companies. They are key to implementing, managing and conducting internal audits of such systems. Obviously there are other auditing and verification layers but these staff members are where the rubber hits the road.

On a personal level, during my teaching career, I had always advised students about the fact that they are, in essence, the guardians of public health by ensuring that safe, nutritious food enters the consumption chain. The present disaster, for that is what it is, thus serves to illustrate this point. However, notwithstanding the crucial role played by such staff, they are sometimes not rewarded accordingly. My understanding of value for money in terms of a salary is that you are paid based on the risks that presents itself in meeting your job requirements. Ensuring such safety practices in this environment does carry many risks, with failure leading ultimately to that we are reading about today.

When engaging in casual or formal talks with many different role players, it does not seem as if this is always taken into account, and recognized as such, by all companies, both large and small. In fact, in instances, the quality management and control teams are sometimes deemed a necessary nuisance and are treated as such. Similarly with salaries paid. Young food technology graduates are place in positions with a large responsibility at minimal salaries to appease the gods of food safety while minimizing the payroll. On occasion, based on adverts I see and feedback from alumni, in some smaller companies especially, employees are kept on a short-term contract immediately prior to audits to fix a system and then dispensed with soon after the audit. And one could expand on this in detail were there space for it.

I have two problems with this:
a. By devaluing the crucial role played by such persons based on an inappropriate salary certainly has implications for food safety. The incumbent feels this lack of appreciation of their role and it may, especially for younger personnel, lead to stress and demoralization. This in turn could lead to shoddy workmanship.
b. Furthermore, fellow staff may also view the position of such an incumbent as being of lower value, concomitantly affecting adherence to standard operating procedures.

We need to ensure that personnel employed in such quality assurance and control positions must be made to feel valued, encouraging scrupulous attention to food safety detail. The reward is a better internal food safety system and better compliance with good manufacturing practice.

Furthermore, some form of certification or accreditation is needed to place additional value on such positions and qualifications of the personnel involved. This needs to go beyond the tertiary qualifications needed by such personnel, akin to registration of engineers with the Engineering Council of South Africa. One avenue that may be followed, but is not yet valued by the food industry, is registration with the South African Council of Natural Scientific Professions.

In terms of the bigger picture, a valued and happy workforce will inevitably lead to better outputs, including that of food safety. Recognize your personnel involved in this crucial role or else you may have to ‘fess up one day, heaven forbid!

Students take on SAB Intervarsity Beer Brewing Challenge

A group of CPUT brewers are set to defend their title at this year’s SAB Intervarsity Brewing Cup.

In 2014, CPUT walked away with the top prize, thanks to a group of Food Technology students who scooped the “Ben Lamaletie”  IBD Intervarsity Beer Brewing Challenge Floating Trophy, the top honour Castle Lager Best Bru Award, as well as the Carling Black Label Champion Lager.

The win was a huge achievement for CPUT which is one of the newcomers to the competition, having made its debut in 2013.

This year’s team is already hard at work, having started their brewing process in June.

BTech Food Technology student Brian Gomes says they are working on three brews, which includes a larger, specialty beer (Belgian wit) and a cider.

Gomes says this year the competition organisers have tasked students to incorporate African plants in their specialty ale.

Gomes says they researched various indigenous plants and also approached traditional healers to found out more about herbs and their individual properties.

“I found an indigenous plant that will add a sweet flavour to the specialty ale,” he says.

The team is currently working on fine tuning their specialty beer and has already completed their larger, which is now maturing.

The group will compete against chemical engineering, biochemistry and microbiology students.

Dried, salted and preserved

A Service Learning Project that got off the ground in 2013 is soon set to benefit rural fishing communities.

The Fish Drying Project is an initiative of the Food Technology Department and the organisation Envirochoice, and is aimed at providing sustainable food solutions to impoverished communities.

Lecturer Suné St.Clair Henning, who is coordinating the project, says second-year students following the department’s extended curriculum programme have been involved since the project’s inception.

“We have developed a process to dry fish for human consumption,” she says.

The fish is salted and placed on bespoke bins that are sealed with pallets and then left to ferment for a specific period. The bins are then titled, with the fish left to dry for a further period on the pallets.

“So far we have tested different types of fish species to see what is suitable for this process,” says St.Clair Henning.

Currently the students are working on the last trial and completing chemical and microbiological analysis on the dried product. They will then compile a report that will be submitted to the project partner.

Henning says together with Envirochoice they will identify a rural fishing community and will then train individuals how to dry fish, following the method devised by the students.

The students will also compile a training manual for the community members.
