and Fresh Produce: Investigating the Sanitizing Potential of Antibacterial Remedies.
Many of our favorite foods have suffered from bacterial contamination over the past few years, including spinach, peppers, tomatoes, peanut butter and pistachios. In response to these food contaminations, Andrew Sherlock designed his experiment to test low-cost antibacterial remedies for washing produce. He tested six different treatments including distilled water, salt water, and four different concentrations of chlorinated water, on carrots and lettuce, which were contaminated with a harmless strain of E. coli. Next time you wash your veggies at home, try rinsing them in salt water: Sherlock found that a 1 tablespoon salt, 100 milliliter mixture was more effective than two of his chlorine solutions.
