    Plating up food safety

    Food safety test with agar

    How a paper-thin film has changed the way scientists perform food safety testing

    Three decades ago, microbiologists who conduct food safety tests were introduced to a new, more efficient and accurate way to detect bacteria in foods.

    • Up until then, lab technicians spent hours preparing Petri dishes for microbial analysis – a cumbersome and tedious process. When 3M™ Petrifilm™ Plates were introduced, the need to prepare, purchase and store Petri dishes was eliminated.

      Passing the food safety test

      Food manufacturers test their products for possible bacteria, and they go through those tests like candy.

      Today, ready-to-use 3M Petrifilm Plates are an industry standard. There’s a version for almost any kind of food safety test – from E. coli and Listeria to Staph, Salmonella, Yeast and Mold.

      Why does this matter? Because one in six Americans will get sick this year from something they eat, according to the CDC. Somewhere behind many of the things we eat is someone testing to make sure our food is as safe as possible.

      And the good news? The paper-thin plates offer users a 66 percent reduction in waste, use 76 percent less energy, 79 percent less water and produce 75 percent fewer greenhouse gases. That’s a significant reduction in the overall environmental impact when compared to traditional agar test methods.

      Food that doesn’t make us sick, tested in a more environmentally friendly way? Sounds delicious.
