Do you have a knife block in your kitchen? Better read this...

When was the last time you washed your can opener or that knife block? 

Those are a few potentially gross gadgets in your kitchen that could be harboring Salmonella, Listeria and E. coli. Microbiologists at NSF International, a global public health and safety organization, set out to find the filthiest spots in our kitchens and found these top 10 culprits of contamination:

1. Refrigerator water dispensers

2. Rubber spatulas

3. Blenders

4. Refrigerator vegetable compartments

5. Refrigerator ice dispensers

6. Refrigerator meat compartments

7. Knife blocks

8. Rubber seals of food storage containers

9. Can openers

10. Refrigerator insulating seals

Most of these spots are perfect breeding grounds for germs, which love dark, moist areas. A lot of us either don’t clean the spots that we don’t see or put certain utensils away in their dark spots before they’re thoroughly dry – and could slice, dice, dispense or blend contamination into our next meal.
