Listeria: Spain Third Highest In EU For Cases Of Listeriosis

The UK sandwich outbreak

Following an investigation, Public Health England confirmed on the 7th of June that the outbreak was linked to pre-packed chicken sandwiches that contained the deadly bacteria and of which had been consumed by the victims.

Experts have now linked the outbreak to chicken sandwiches that were made at the inappropriately named ‘Good Food Chain’ in Stone, Staffordshire, which provides food to a large number of NHS Trusts and shops in the UK.

The original source of the Listeria was thought to be from the meat supplier North Country Cooked Meats, which supplied meat to the Good Food Chain, but is now thought to have ceased production.

Spain: third highest in the EU

Spain has also seen its fair share of Listeria cases in recent years. In fact, the country has the third most cases within the EU with around 70 deaths being attributed to Listeriosis each year since 2009.

The problem has become so severe that medical experts in the country have said that tackling Listeriosis is one of their biggest challenges.

What is Listeria?

But what exactly is Listeria and how can we avoid it?

Listeria is a bacteria that if ingested can develop in the cells of the body and lead to Listeriosis.

Listeria is one of the most virulent food based pathogens and can cause serious health complications and death in around 20-30% of cases. Those most at risk are young children, pregnant women, the elderly and those with weak immune systems.

Although you can catch Listeria from another person who is infected or if around farm animals giving birth, the most likely source of infection is from contaminated foods.

Foods most likely to carry it

Some of the most common are:

• Unpasteurised milk
• Dairy products from unpasteurised milk
• Soft cheeses
• Chilled foods such as meats, sandwiches and pates.

Listeria can withstand freezing temperatures, oxygen starvation and unlike other bugs, does not spoil the food making it difficult to detect.

Symptoms and how to protect yourself

The initial symptoms for someone who has contracted the Listeria bug are:

• Aches and pains
• A high temperature
• Fatigue
• Vomiting or sickness
• Chills
• Diarrhoea

More severe symptoms are seizures, severe headaches and neck pain as well as confusion.

As mentioned earlier, Listeria can be difficult to identify, but there are some things you can do in order to reduce the chances of being infected. These include:-

• Washing your hands thoroughly after preparing any meat.
• Do not drink unpasteurised milk or cheeses made from it.
• Avoid Hispanic-style cheeses such as Queso Fresco, Queso Blanco, Panela unless labelled as being made with pasteurised milk.
• Wash fruit and veg before eating them.
• Make sure food is steaming hot before eating it.
• Make sure you store ready-to-eat foods correctly as outlined by the manufacturer.
• Practice good food hygiene at ALL times.
