Pre-packaged produce: dos and don’ts
Some packaged fruits and veggies should be washed before eating
Just because they may be pre-packaged when you buy them at the store does not mean that some fruits and vegetables do not need washing before you eat them. Read the package to see if it says “washed,” “triple washed” or “ready to eat”; if not, rinse the produce under cool running water (after washing your hands). Scrub firm veggies and fruits (melons, cucumbers) with a (clean) produce brush, and dry with a paper towel or a clean cloth.
