Salmonella Has Been Proven To Grow In The Juice At The Bottom Of Bagged Salad, Here's How To Avoid Being Poisoned:

Food poisoning isn't fun - the sour stomach, the mad-dash to the toilet and those frantic moments as you try to recall everything you ate within the last few hours.

Whatever you ate, it's likely that you feel lousy because of Salmonella.

Salmonella is a bacteria that can cause food-borne infection, or food poisoning. It is usually spread by eating contaminated food, but it can also be spread from person-to-person.

Now, it could be growing in your salad.


The American Society for Microbiology has just released a study that proves Salmonella can thrive in bags of leafy greens.

According to the study, salad juices in water increased Salmonella growth on the leafy greens. The salad leaf juices also enhanced Salmonella's ability to attach to the salad bag plastic.

So, over 5 days of refrigeration (the average storage time for bagged salad), traces of juice in the bottom of the bag increased Salmonella growth and colonization directly on the salad leaves by about 350%.

The food safety community is suggesting that consumers need to be extra cautious about the way we wash and store our salads - especially the kind that we buy in bags.

In the US, beansprouts contaminated with Salmonella infected more than 100 people in 2014 - a quarter of whom were hospitalized. In February 2016, over 50 Australians contracted a rare strain of salmonella after eating bagged leafy greens and two people died in July 2016 from E. coli in the UK after eating contaminated salad leaves.

Some key suggestions for salad safety are:

  • Put your lettuce in a big bowl covered in plastic wrap, or Tupperware with a paper towel on top to collect condensation
  • Thoroughly wash your leaf lettuce before eating them
  • Eat before the expiration date

f you follow these steps, you should be able to avoid food poisoning. Or, you can just stop buying salad in a bag.


Whatever you choose, just be sure to take extra care with your produce!
