When you might concentrate on the dangers of a unclean sponge used one too many instances — and even how your kitchen sink might function a reservoir of micro organism — when’s the final time you cleaned your spice jars?
It seems these inconspicuous kitchen staples could also be among the many major culprits for cross-contamination, and pose maybe the very best contamination threat in your kitchen.
48% of Spice Containers Had been Contaminated
In a examine commissioned by the U.S. Division of Agriculture’s Meals Security and Inspection Service,2 researchers with Rutgers Faculty of Environmental and Organic Sciences and colleagues analyzed 371 adults cooking turkey burgers in kitchens starting from apartment-style to these in instructing places and meals banks.3
Poultry, together with rooster and turkey, are among the many high sources of Campylobacter-related sicknesses, with the micro organism inflicting 0.8 million foodborne infections per 12 months within the U.S.4 As famous within the Journal of Meals Safety:5
“In keeping with the Interagency Meals Security Analytics Collaboration, 40.5% of nontyphoidal Salmonella sicknesses have been attributed to Meals Security and Inspection Service (FSIS)-regulated merchandise, whereas 78.8% of all nondairy Campylobacter sicknesses have been attributed to FSIS-regulated merchandise that features, in descending order, rooster, turkey, different meat or poultry, beef, pork, and sport (0.6%).
Clearly, improper dealing with of uncooked poultry, resembling insufficient cooking, poor hand washing, and cross-contamination of ready-to-eat (RTE) meals within the residence, can lead to the event of foodborne sickness from such pathogens.”
To find out simply how prevalent cross-contamination is on kitchen surfaces throughout strange meal preparation, the researchers requested contributors to organize a meal of uncooked floor turkey patties with seasoning and a prepackaged salad. The meat was inoculated with a bacteriophage known as MS2 to function a tracer all through the kitchens.
The themes didn’t know their meals security behaviors have been being scrutinized till after the meal was already ready. The researchers then swabbed quite a lot of widespread surfaces, together with sink faucet handles, kitchen utensils and spice containers. Surprisingly, the handles of sink taps turned out to be least contaminated, whereas spice containers have been probably the most.
About 48% of the spice containers have been contaminated with MS2 — considerably increased than most different kitchen surfaces examined, which usually had contamination frequencies of lower than 20%.6 Slicing boards and trash can lids have been the No. 2 and No. 3 most contaminated objects. In keeping with examine coauthor Donald Schaffner, a distinguished professor within the Division of Meals Science at Rutgers, in a information launch:7
“Along with extra apparent surfaces like reducing boards, rubbish can lids and fridge handles, right here’s one thing else that it is advisable take note of while you’re attempting to be clear and sanitary in your kitchen. Our analysis reveals that any spice container you contact while you’re making ready uncooked meat would possibly get cross-contaminated. You’ll wish to take heed to that in or after meal preparation.
… We have been stunned as a result of we had not seen proof of spice container contamination earlier than. Most analysis on the cross-contamination of kitchen surfaces resulting from dealing with of uncooked meat or poultry merchandise has targeted on kitchen reducing boards or faucet handles and has uncared for surfaces like spice containers, trash bin lids and different kitchen utensils.
This makes this examine and comparable research from members of this group extra complete than earlier research.”
What Different Kitchen Surfaces Have the Most Germs?
Micro organism are just about in all places, and so they’re not at all times trigger for alarm. Nevertheless, when washing dishing be cautious of reusing sponges too many instances, as research repeatedly rely them as among the many most contaminated kitchen objects.
In a examine performed in 10 U.S. kitchens, 67% of sponges examined optimistic for fecal coliforms, whereas 33% contained E. coli.8 Different analysis discovered Salmonella in 15.4% of sponge samples, whereas a hygiene examine revealed kitchen sponges had the second highest load of coliforms — solely drain traps have been increased.9 As famous in BMC Public Well being:10
“Throughout cleansing meals residues might adhere to the sponge floor and damp websites resembling sink areas can act as additional microbial reservoirs that may contaminate the sponges throughout their use. Subsequent poor dealing with, storage or improper disinfection of kitchen sponges will result in additional microbial progress at room temperature.
Consequently, kitchen sponges are a significant supply of cross-contamination as they’ll transmit foodborne pathogens, infectious brokers and spoilage inflicting microorganisms to meals contact surfaces.”
In one other examine, researchers analyzed 14 used sponges and located 45 billion microbes per sq. centimeter.11,12 Dish sponges harbor the most important variety of E. coli and different fecal micro organism within the common residence, possible as a result of they are not changed as they need to. A variety of research have confirmed kitchen sponges comprise the very best variety of micro organism on family merchandise.13
Can Kitchen Sponges Be Cleaned?
Each sponges and brushes used for dish washing are usually contaminated with nonpathogenic micro organism, though the brushes contained decrease ranges in a single examine.14 Additional, when brushes have been contaminated with Salmonella and allowed to dry in a single day, the micro organism died extra quickly than in sponges.
“The ends in the current examine indicated that cleansing utensils that dried between use would have decrease numbers of micro organism together with pathogens,” the researchers defined, and advised utilizing brushes, which dry extra simply between makes use of, in lieu of sponges. In addition they said you possibly can assist forestall Salmonella progress in sponges by:15
- Altering the sponge when it’s worn
- Not storing the sponge within the sink
In keeping with the USDA, microwaving sponges correctly may additionally kill as much as 99.99999% of micro organism, whereas working them via the dishwasher kills 99.9998%.16 In case you do put your sponge in your microwave, be certain it doesn’t comprise any metallic supplies.
Michigan State College additionally advises the sponge be fully moist while you do it, because it might catch hearth or explode within the course of if it is not.17 The moist sponge needs to be positioned on excessive for one minute and left to chill for as much as quarter-hour so you aren’t getting burned.

Slicing boards are one other main offender relating to harboring harmful micro organism. Specialists suggest having a minimum of two reducing boards, one for meals safely eaten uncooked, resembling fruit and veggies, and the second particularly for reducing uncooked meat, poultry and fish.
Surfaces you employ to cut your meals might harbor micro organism together with E. coli and Salmonella. Since plastic reducing boards have been simpler to sanitize, they have been typically considered safer. That was till the Eighties when a College of California Davis researcher investigated and located though they’re simpler to sanitize, reducing typically nicks the plastic, giving micro organism a spot to cover.18
Wooden could also be more durable to sanitize, however it doesn’t nick as simply. Additional, when wooden, plastic and chrome steel surfaces have been in contrast, Campylobacter survived the longest on plastic.19
The U.S. Division of Agriculture recommends washing your reducing board in sizzling soapy water after every use and permitting it to fully air dry earlier than placing it away. Bamboo reducing boards are more durable and fewer porous than wooden, soak up little moisture and resist scarring from knives. Importantly, substitute your worn boards as they develop hard-to-clean grooves.20
Your kitchen sink can also be prone to be a supply of contamination. In a single examine, contributors ready breakfast utilizing uncooked sausage, eggs and a fruit salad made with cantaloupe. After preparation, the kitchen sink was the floor most frequently contaminated, with 34% discovered as such. Maybe in consequence, 26% of the cut-up cantaloupe examined was additionally contaminated, as it might have been positioned within the soiled sink for laundry.21
