Listeria Control Management

Comprehensive Listeria Control Managing, Treating, and Preventing Outbreaks

Maintaining effective control over Listeria bacteria is essential for the food processing industry. With recent recalls and outbreaks affecting household brands, it’s essential for businesses to implement robust management and treatment strategies. In this blog, we will delve into the causes of Listeria, signs of contamination, methods to eliminate Listeria, and most importantly, prevention measures to combat future outbreaks.

What is Listeria?

Listeria bacteria is a type of bacteria that can cause serious issues in food processing facilities. The bacterium is typically found in natural sources such as soil, water, and natural ingredients. It is widely found in animals, causing listeria to spread into poultry and red meat.

Listeria bacteria is a resilient bacterium and can live and adapt in many environments. It can survive in both high and low temperatures and can adapt to a range of pH levels and salt concentrations.

Listeria is known for causing the disease Listeriosis. Listeriosis can cause serious infections in humans and animals. It is caused by eating food containing listeria bacteria. Listeria bacteria can be found in a lot of food but is typically found in cooked meats, aged dairy, pre-prepared food, and ready meals.

What Causes Listeria Contamination?

Listeria bacteria can contaminate food products at various stages of production, processing, and distribution. The key and most common causes of listeria contamination includes:

  • Raw Materials: Listeria is typically introduced into food processing facilities through contaminated raw materials, such as animal products, fruits, and vegetables. It is imperative to handle and store raw materials effectively and timely to prevent listeria spread.
  • The Processing Environment: Listeria can survive on various surfaces, equipment, and utensils. Incorrect sanitisation can lead to Listeria contaminating food products during processing.
  • Cross-Contamination: If listeria is present, it can spread to other areas within a facility, leading to cross-contamination. This can occur through contact with contaminated equipment, tools, or employees.
Signs of Listeria Contamination:

As specialists within the food processing industry, our SymClean professionals are trained to spot the signs of Listeria. Recognising the early signs of listeria could make the difference in the mitigation process.

Indications of Listeria Bacteria in your factory will often be found in food products. Contamination in these products may not always be visually obvious. However, there are some indicators to be aware of, such as:

  • Odour: If a food product emits an unusual or foul odour, it could be a sign of Listeria contamination. Ensure your teams are familiar with how foods should smell and indicators of something being ‘off’.
  • Discolouration: Listeria can also cause physical changes such as discolouration in food. Look for any unusual colour changes, such as dark spots or abnormal hues.
  • Abnormal Texture: Pay attention to the texture of food products. If you notice sliminess, excessive moisture, or a mushy consistency, it could be an indication of Listeria contamination.

Listeria may also present itself via your workforce. Listeriosis has minor symptoms but understanding what it looks like could help you to eliminate the bacteria spread throughout your factory. Symptoms include temperatures, sickness and diarrhoea, and pain.

Listeria Prevention 

The Key to Avoiding Outbreaks 

Correct cleaning and sanitisation practices are vital in order to effectively prevent Listeria contamination. Thorough cleaning and sanitisation, regular scheduled deep cleaning, and utilising appropriate cleaning products and techniques, will help to ensure the elimination of Listeria bacteria as well as creating a hygienic environment.

As well as this, ensuring your food processing plant has strict protocols in place will also combat the likelihood of a Listeria Outbreak. Implementing rigorous guidelines and procedures such as personal hygiene, use of products, and sanitisation standards will significantly reduce the risk of listeria confirmation.

Educating your team about Listeria is fundamental in efforts to prevent Listeria Outbreaks. Ensure your team is actively involved in preventing Listeria contamination by providing compulsory training that educates them about the risks associated with Listeria, proper hygiene practices, and the importance of adhering to cleaning and sanitation protocols.

SymClean recommends that food manufacturers implement regular testing and monitoring for all bacteria. There are also multiple legislations in the UK which businesses must adhere to. Following principles like HACCP will allow for early detection and prevention.
