Everything You Should Know About Listeria & Listeriosis
From spinach and sprouts, to hummus and ice cream, foodborne outbreaks are more commonplace than you’d expect; and Listeria is one of the main culprits. When a Listeria outbreak happens, it can cause serious interruptions to the food service industry. Just look at a few years ago, when Jeni’s Ice Cream and Blue Bell Creamery shuttered kitchens and scoop shops to better understand and eliminate the source of a recent contamination. So what exactly is Listeria, and how does it get into our food and into our bodies? And perhaps most importantly, what must manufacturers do to clean it up?
What is Listeria?
Listeria is a common bacterium found in soil and water that is easily transmitted to kitchens and manufacturing facilities via raw vegetable or animal products. Once it contaminates an area, it can be challenging to get rid of; unlike most bacteria, Listeria grows well in refrigeration. Often found in processed meats and unpasteurized dairy, Listeria may infect other foods through contact with affected equipment.
Symptoms of Listeria/Listeriosis
When a person contracts Listeria, it causes symptoms that mimic food poisoning. If someone has invasive listeriosis, meaning the bacteria spread beyond the gut, symptoms can include:
- muscle aches
- gastrointestinal complications.
- stiff neck
Listeria generally impacts only the elderly, people with compromised immune systems, and pregnant women. It can cause miscarriage, stillbirth and premature labor for women, and may lead to serious illness or death in newborn babies and older adults. Most healthy children and younger adults can consume Listeria with little ill effect.
How to Prevent Listeria Outbreak
To keep an environment free from Listeria, there are a few things to keep in mind:
- Before you can eliminate bacteria you must first remove all grime and dirt from a surface area. This allows the disinfectant treatment to reach the source of the problem.
- Combination detergent/sanitizers are typically ineffective against Listeria outbreaks. An EPA-registered stand-alone disinfectant helps guarantee that deadly bacteria is eliminated.
- Clean/disinfect often. Increasing the concentration of product will not compensate for inadequate cleaning. When using any cleaning product, follow the manufacturer’s directions exactly. Disinfectants must be applied in the prescribed amount and left on surfaces during a “cure time” in order to fully treat the area.
How to Test for Listeria
The most effective way to tell if you’ve been infected by Listeria is via blood test. In some cases, urine or spinal fluid tests may also be in order. That being said, antibiotic treatment will likely begin before a confirmed diagnosis, particularly if you are susceptible (pregnant, elderly, or weakened immune system) to the more severe symptoms.
