Dear Reader,

Buying frozen foods is a standard practice for most folks.

In fact, 99 percent of U.S. households consume frozen foods, making the frozen food industry $31 billion annually.

And while it has seen a bit of a decline in sales lately, chances are you have at least a few frozen food items in your freezer right now.

Which is exactly why you need to keep reading this.

Even though frozen foods are of endless variety, one item in particular might come to mind for you — produce.

Frozen vegetables and fruits are a convenient and often inexpensive way to add a few extra vitamins, minerals, and flavors to any meal. Plus, with frozen fruits and veggies, you don’t have to stick to what’s in season — you can eat what you want when you want it.

And you don’t have to worry about the dangers of BPA like you do with canned veggies.

However, this doesn’t mean you’re out of the danger zone.

Last week, the CDC and FDA ordered a voluntary recall of over 350 frozen produce products due to an outbreak of a deadly food-borne disease. We will share more specific brand information later on.

You might be thinking, How on Earth can bacteria survive in the freezer?

Well, prepare yourself — this microbe doesn’t die easily.

An Outbreak in Slow Motion

Thanks to a new tracking tool, the CDC found that the current outbreak is caused by the same strain of Listeria responsible for outbreaks in 2013, 2015, and the one in February of this year. The CDC confirmed this through the bacteria’s DNA.

Meaning this outbreak has been unfolding in spurts over the last three years.

Frozen produce manufactured in Pasco, Washington, by CRF Frozen Foods is the “likely source” of this outbreak, according to the CDC.

The CDC explains a little more about Listeria:

Listeria monocytogenes is commonly found in soil and water. Animals can carry the bacterium without appearing ill and can contaminate foods of animal origin, such as meats and dairy products… When Listeria bacteria get into a food processing factory, they can live there for years, sometimes contaminating food products.²

The University of Georgia’s Center for Food Safety director, Michael Doyle, thinks one reason for this prolonged outbreak is “resident” Listeria. Unlike their “transient” counterparts that contaminate food as they move through the processing plant, resident bacteria are able to establish themselves in the processing plant and survive for many years.

He went on to say, “The organism’s quite hardy.”³

So far, this hardy strain has taken the lives of two people, one in Maryland and one in Washington state, and hospitalized six others.

However, since the infection caused by Listeria (listeriosis) kills one in five victims, making it more deadly than E. coli and salmonella, it’s likely there will be more deaths and illnesses reported in the days to come.⁴

Older adults, pregnant women, newborns, and those with weakened immune systems are more susceptible to infection.

If you’re an older adult, your risk of infection greatly increases. In fact, anyone over 65 is four times more likely to contract illness from Listeria than the general population.

Icy Precautions

The best way you can protect yourself from this outbreak is to discard any contaminated products from your freezer.

Check all items in your freezer against the FDA’s recall list. It provides detailed brand and SKU number information. If any of your items match up, you can return them for a refund or simply pitch them. Click here for the FDA recall list.

But that may not protect you from the long reach of this slow-motion outbreak.

So here’s an extra tip for added protection…

Buy a thermometer.

As we mentioned before, these bacteria can live in cold temperatures. However, experts suggest keeping your freezer at 0 F (-18 C) in order to halt Listeria growth.⁵

And the best news, you can purchase a commercial-grade appliance thermometer for around $6 on Amazon. Click here to check it out.

While you’re there, you might want to pick up one up for the fridge too. 40 F (4 C) or below is the optimal temperature for your fridge to halt Listeria growth on fresh foods.
