Biotech in action

Our Story

Our Story

For over 20 years the SGA team have been providing professional cleaning services to industrial and commercial food manufacturing plants across Australia. We employ over 400 dedicated and experienced staff across our sites who are key to the success of our business.

At SGA we are continually seeking new innovations and pushing the boundaries of effectiveness and validity in everything we do. We have pioneered the use of advanced biotechnology in our products and processes, and as our business continues to grow we are constantly developing and pursuing new solutions to combat bacteria in food manufacturing.

We do more than deliver on cleaning services and equipment: Our experienced team can streamline your processes and provide you with a 360-degree tailored solution that’s suitable for the needs of your business. We invest heavily in training and work with you and your staff to implement the correct methods of process and safety.

We continue to build solid, long-term relationships with our valued customers and suppliers. We ensure your business continuously exceeds industry and auditing standards so your production facility operates at its full capacity every day.

“We are using our knowledge and expertise to deliver you the best customer experience along with the best solutions for your business.”


Our business is built around delivering solutions to fight the microorganisms that inhabit and contaminate the food production process. The appearance of bacteria and toxins in food manufacturing results in food spoilage and disease, leading to financial repercussions and a bad reputation.

Our process is simple:

We use the latest technology
Source the best suppliers
Deliver the highest quality products and services
We are at the forefront of advanced biotechnology
Use of bacteriophages and persistent sanitisers to combat bacteria in food production

Bacteria multiply rapidly, and the consequences can be toxic. Don't let bacteria spoil your reputation.

Biological Contaminants

Biological Contaminants

Biological contamination occurs when bacteria or toxins contaminate food, causing food spoilage and food poisoning when ingested. The most common bacteria found in food are salmonella, listeria, escherichia, clostridium and campylobacter.

Bacteria in food manufacturing forms from human contamination, airborne pathogens, poor food handling and storage, and equipment contamination, just to name a few. Bacteria multiply rapidly, and the consequences can be toxic and dangerous.

Traditionally bacteria are treated by continually applying a combination of chemicals and disinfectants with a broad-spectrum application method, or ‘scattergun’ approach that is not specifically targeted. These procedures are often unsanitary and fail to keep these hazards under control.


Did You Know That Even Bacteria Can Get A Virus?

The virus that infects bacteria are known as bacteriophages, or phages for short. Phages were discovered in the early 1900s, and their use has been extensively researched with positive results.

At SGA, we use bacteriophage technology in our cleaning processes. Phages only infect certain types of bacteria cells, namely the biological contaminants we aim to target in your plant. This means they are not harmful to humans, animals, or plants because they specifically target and kill bad bacteria.


How Do They Work?

Phages attach themselves to the surface of the bad bacteria and inject their DNA into the cell. As the phage replicates its DNA inside the bacteria cell, one of two things happen: The cell bursts and hundreds of newly created phages are released, known as the Lytic cycle. Alternatively, the bacteria cell lays dormant while the phage continues to replicate its DNA inside, and once the conditions are right the Lytic cycle occurs, and the cell bursts.


The Result:

The original contaminant is destroyed, and your facility is visibly and microbiologically clean to a level unachievable with traditional and chemical-based methods.

This is not only a chemical-free solution; it is a specialized process. Different types of phages are designed to destroy different bacteria. Whether it be salmonella, listeria or any other bacteria common among food products, phages have the upper hand when it comes to hygiene. It is a solution tailored to your environmental requirements, ensuring you exceed the highest standards in food quality assurance.

Persistent Sanitiser

While traditional sanitisers reduce bacteria to a safe level, they can leach from the surface and reduce efficiency when met with human contact, airborne pathogens or spills. Consequently, chemicals are required more frequently to ensure bacteria does not reinhabit the surface.

We use Fresche technology, a persistent sanitising agent containing unique molecules that bond to the surface. It continues to shield and clean the surface against bacteria and toxins for extended periods due to its persistent and residual nature.

Its durability means your surfaces stay cleaner for longer, making it a cost-effective solution, while its compounds are safe for humans, animals and the environment, making it one of the most environmentally friendly products available.
