Best Sample-Best Result: Compositing Environmental Samples

To composite or not to composite? No, I am not trying to put a Shakespearean twist on this blog, but rather answer a question often asked when sending in environmental samples.

Best Sample-Best Result: EMP Sample Location

A while back as I talked with a manufacturer that was required by their customer to have an environmental monitoring program, they had expressed their confusion in their customer’s response when they shared their monitoring results. The manufacturer was proud to present 3 years’ (the entirety of their program) worth of data in which they never once had a positive result for the target bacteria. The manufacturer thought they had been doing an amazing job while their customer was less than confident with their results. The customer knew that given the manufacturers environment and required sanitation it was highly unlikely to never have a positive result, not because the manufacturer wasn’t taking care but, because of the ubiquitous nature of bacteria. Ultimately, the customer felt that the manufacturer was not sampling the most likely growth areas in their facility and was therefore missing the bacteria.

Best Sample-Best Result: Environmental Sample Size

Do You Follow The Rules: Plate Counting

As I scroll through Facebook I occasionally see posts challenging the reader to find the correct answer to a relatively simple mathematical equation. While we can look at it and say there must be only one correct answer, there are typically a variety of different answers in the comments below. Are those people responding unable to add, subtract, multiply, and divide? Possibly, but more commonly they forget simple rules called the order of operations. Simply put conduct the math functions in order parentheses, exponents, multiply, divide, add, and then subtract.

3 Common Misconceptions About Being a Food Laboratory Technician

This month Cherney features Kea Schmuhl, one of our dedicated Sample Preparations Technicians who looks to clear up some of the misconceptions about working in a testing laboratory.  Thank you to Kea for her insight and unique perspective!

When people ask me what I do for a living and I say, “I’m a Sample Preparation Technician,” or work in a “Food Safety Testing Laboratory” they often make generalized assumptions. These thoughts tend to be based on the stereotypes they have seen on TV or read in a book portraying laboratory technicians.  However, quite a few of these assumptions are not the case when describing my role as a Sample Preparation Technician at Cherney.
