For many Ghanaians, the rhythmic sound of a wooden pestle hitting a mortar is more than food being prepared.
It is the sound of home, family and tradition.
Growing up in Nsawam Djankrom, I knew that familiar sound very well.
Pounding fufu was hard work, but it was also part of our culture.
Today, that familiar sound is increasingly being replaced by the hum of mechanised fufu-pounding machines.
These machines save time, reduce physical labour and increase production.
The technology began transforming fufu preparation in Ghana in 2004, with early mechanised systems associated with innovators such as Fadegnom Charles and subsequent refinements involving Professor Kwadeo Kesse, Dr Lawrence Ansong, and R. E. Dodoo.
But as we modernise how we prepare our food, we must also modernise how we protect it.
The question is simple: Have our food-safety practices kept pace with our technological convenience?
And this is not simply a hypothetical concern. Research conducted in different parts of Ghana has documented bacterial contamination associated with food-milling equipment, including machines used to prepare fufu.
A 2022 study in Tamale by Professor Sabah and colleagues examined 50 fufu-grinding machines and found Salmonella contamination in 48 per cent of the machines sampled.
Of 100 samples collected from the machines and the fufu processed through them, 27 per cent tested positive for Salmonella. More concerning, 81.5 per cent of the Salmonella isolates showed resistance to three or more antibiotics.
More recent research in Somanya has also reported high bacterial loads in food-milling machines, including Klebsiella, Enterobacter, E. coli and Salmonella.
These findings do not mean that every person who eats machine-processed fufu will become sick.
They do, however, demonstrate that food-processing equipment can become a point of microbial contamination when sanitation is inadequate.
What is happening inside the machine?
Part of the concern lies in the design and operation of these machines.
Commercial fufu-pounding machines have internal chambers, moving components, joints, seals, and other spaces that may be difficult to access and clean.
Wet, starchy cassava and plantain mixtures can leave residues in grinding chambers and around moving parts.
This is where an important food-safety concern emerges.
Trapped food residues can provide nutrients and moisture that may allow microorganisms to survive and multiply.
Under favourable conditions, microorganisms can attach to food-contact surfaces and form biofilms, structured communities that can be more difficult to remove through inadequate cleaning.
A machine may therefore look clean on the outside while microorganisms remain in areas that are difficult to reach.
If those areas are not properly cleaned and sanitised, contamination can potentially be transferred to the food being processed and ultimately enter our dining tables.
Problem is bigger than machine
Food safety is a chain, and the machine is only one link.
Cleaning, maintenance, hand hygiene, money handling, and regulatory oversight all influence the safety of food sold to consumers.
In an Asante Mampong study by Dr Dennis Dekugmen and colleagues, published in 2023, only 12.7 per cent of surveyed milling operators reported having an operating license. Only 32.7 per cent knew that milling machines could become contaminated with microorganisms, while 85.5 per cent reported maintaining their machines only when they broke down.
A food-processing machine should not receive attention only when it stops working. Maintenance should include sanitation, preventive inspection, and regular cleaning, not simply mechanical repairs.
The responsibility also extends beyond machine operators.
Food handlers must practice proper hand hygiene and prevent cross-contamination.
Consumers, too, have a role in demanding hygienic food-processing environments.
Regulators must provide oversight, while manufacturers have a responsibility to consider food safety when designing equipment.
Fufu deserves the same food-safety attention as every other food.
Processing food faster does not automatically make it safer.
What matters is whether technological convenience is accompanied by proper sanitation, food-handler practices, hygienic equipment design, and effective oversight.
The problem is not mechanisation.
The problem is mechanisation without adequate food-safety controls.
When technology enters the food system, food safety must enter with it.
So, what should we do?
We do not need to abandon mechanised fufu pounding.
We need to make food safety part of modernisation.
First, make sanitation a standard operating procedure.
Operators should have clear procedures for removing food residues, washing, sanitising and drying equipment.
Municipal authorities and the Food and Drugs Authority should incorporate practical sanitation requirements into routine inspections.
Second, strengthen food-safety training.
Vendors and machine operators should receive practical training in hand hygiene, cross-contamination prevention, cleaning, sanitation, and separating money handling from food contact.
Training should explain not only what operators must do, but why these practices matter.
Third, design machines with food safety in mind.
Manufacturers should minimise inaccessible crevices and ensure that components requiring regular cleaning are accessible and detachable.
If a food-processing machine cannot be properly cleaned, food safety has already been compromised at the design stage.
Fourth, strengthen inspection and accountability.
Metropolitan, Municipal and District health authorities should include commercial food-milling equipment in routine inspections, with licensing linked to meaningful sanitation requirements and periodic checks.
Inspection should also be accompanied by practical guidance and accessible training so that safe practices are achievable, particularly for small-scale operators.
Ghana does not have to choose between tradition and technology.
We can preserve fufu's cultural importance while embracing machines.
But modernisation should not stop at putting a motor on a traditional process.
It must also include better sanitation, stronger training, safer equipment design and effective food-safety oversight.
The question is no longer whether mechanised fufu pounding is part of Ghana's food system.
The question is whether our food-safety systems will evolve with it.
Convenience should make our lives easier.
It should never make our food less safe.
