Protect Yourself from Hidden Produce Pathogens

Correspondent Elisabeth Leamy shares advice on how to rid your fruits and veggies of harmful bacteria.

Protect Yourself from Hidden Produce Pathogens

It’s important to wash conventionally grown fruits and vegetables to help remove pesticide residue. So does that mean if you buy organic, you don’t have to wash your produce? No! And yet many people make the mistake of biting right into organically grown veggies and fruits without washing them first. 

Here’s why that thinking is backwards: Ingesting trace amounts of pesticides now and then probably won’t hurt you (though you should still try to avoid it.). But without proper washing of produce, you run the risk of ingesting a foodborne pathogen, which could be potentially life-threatening.

Foodborne pathogens can be on conventional or organic produce. For example, E. coli bacteria could get onto fruits and vegetables from manure in the soil they were grown in, or from the hands of pickers in the fields or fellow customers in the store.

The CDC estimates 3,000 Americans die from foodborne illnesses every year, including deadly outbreaks in recent years linked to produce like peppers and spinach. But the good news is you can reduce your risk. So whether you buy conventional or organic produce, here are the dos and don’ts for washing it properly.


Wash under running water: Researchers recommend using water over commercial products and home washing brews. Running water is even better because the action of the water dislodges residues and carries them off of the produce. Bunched fruit like grapes can be placed in a colander and then rinsed with running water. You can increase the friction by rubbing the produce with your (clean) hands.

Scrub with a brush: According to Barbara Rowe of the Utah State University Agricultural Extension service, it’s a good idea to use a vegetable brush on root vegetables, melons, cucumbers and citrus fruit because even though we don’t typically eat their skins, when you slice through the skin into the pulp of the produce, you can transfer bacteria to the inside.

Peel fruits and vegetables: The EPA suggests peeling fruits and vegetables, when possible, for an added layer of protection against pesticide residue and foodborne pathogens. 

Trim outer leaves. The FDA says it’s a good idea to trim off the outer leaves of things like lettuce, cabbage and celery, again to remove the outer layer that can contain more germs and residue.

Dry produce: The FDA says one last step is to pat produce dry with a clean towel or a paper towel, which provides one last opportunity for bacteria and pesticide residues to come off.


Use soap: Neither the USDA nor the FDA recommends washing fruits and vegetables with soap. That’s because soap hasn’t been tested or approved for human consumption. Yes, dish soap goes on dishes, which we eat off of, but fruits and vegetables can absorb soap in a way that dishes cannot. Soap can also change the taste of produce.

Soak produce: Filling a basin with water and soaking produce doesn’t work well because the pesticides and germs don’t flow away. Soaking in your kitchen sink is even worse because kitchen sinks are infamous for the number of pathogens they harbor from cooking meat, washing dirty hands, etc.

Re-wash pre-washed: According to the FDA, bagged lettuces and pre-cut fruits are already washed in such a way that germs and residues are minimized. The agency says you can re-wash these items if you insist, but warns that you could actually introduce new germs, if you’re not careful about safe handling practices.

Exercise Caution

Store before washing: Colorado State University says washing produce and then refrigerating it can cause bacteria to grow, because the produce is moist and warm from the water. Washing ahead can also cause produce to spoil faster.  On the other hand, storing pre-washed produce may help keep your refrigerator contaminant-free and may encourage you to eat more fruits and veggies because they’re ready to go. So decide which matters more to you.

Make a produce wash: Dozens of agencies and organizations all say running water is the best cleanser for produce, but if it makes you feel better to use something stronger, you can buy a (non-soap) vegetable and fruit spray or make your own. Spray it on, let it sit five minutes and rinse well with running water. Here’s a good recipe:

1 cup water
1 cup distilled white vinegar
1 tbsp baking soda
1/2 of a lemon


Mix the ingredients together in a spray bottle. Spray on produce and be sure to rinse thoroughly before eating.

Exactly How to De-Escalate Aggression From a Stranger

Follow security Expert Bill Staton's important advice to keep yourself safe.

Have you ever had a tense interaction with a stranger in public? Perhaps your shopping carts accidentally knocked into each other or there was a misunderstanding in communication and the other person gets angry. You may wonder how you can de-escalate the aggression and exit the situation safely. So security expert Bill Stanton has your go-to advice for staying alert and protecting yourself in the face of verbal aggression and physical attacks.


Bill Stanton: "It always starts with something small, like someone being too close to you, or even more common, you get bumped by a shopping cart. You want to look at their eyes first -it may reveal emotional changes. But you can't rely on just that. Look at what their trunk is doing; a person's torso will reveal their intent. Body language like raising hands, heightened expression, tense shoulders — these are natural responses to a person who is feeling threatened and will escalate. They may begin to zero in on the space between you and them, and their voice will get louder and louder. You want to read this before it gets further and becomes explosive."
