Food safety testing: when to consider outsourcing.
You may be asking yourself if it would be better to keep your food safety lab in-house or if it’s time to start outsourcing your testing. There isn’t one simple answer to this dilemma, except the classic “it depends”. It depends on the test volume. It depends on the costs associated with executing the tests required. It depends on the staffing resources available to conduct the testing. It depends on the proximity of a potential contract lab partner, and the time sensitivity to have a result. Let’s explore these factors a bit further and find out when outsourcing might be a good fit for your lab.
A common case for outsourcing is when there is a consistently low need to conduct a certain method, making the investment of the time and materials required to execute internally unjustifiable. For example, if your internal lab conducts fewer Lactic Acid Bacteria (LAB) tests per month than the number of plates in the smallest package of 3M™ Petrifilm™ Lactic Acid Bacteria Count Plates, it might make sense to ask your contract lab to conduct the method at their lab instead. A package of 3M™ Petrifilm™ Plates can last up to a month in the freezer once opened, and 18 months unopened.
Time to result
Some contract labs have developed sophisticated logistics networks so the time to receive your samples from the plant to the contract lab is as speedy as possible. However, it will still inevitably take longer to travel to a contract lab than if the sample was collected in your plant and walked over to the internal lab on the same property. Time to result is critical in many cases. 3M Food Safety has developed rapid quality indicator methods as well as rapid pathogen methods that can be completed in-house or at a contract lab.

Managing an internal lab through turnover, new employee training and performance audits is challenging for any lab manager. While contract labs also face these challenges, many have more robust staffing and even have several staff scientists in rotating shifts to cover operations seven days a week. Outsourcing in times you’re short-staffed may be something you want to consider.
Justifying capital costs
All equipment ages and depreciates over time. When the time comes to replace your lab equipment, you will be asked to justify the costs to your company. Typically, this includes calculating the return on investment and depreciation considerations. You may see justification for capital spend for laboratory equipment, or you may come to the decision to simply outsource the testing to a contract lab.
Considering next steps
Think about your own lab’s operations. How do the factors of volume, time to result, employment challenges and capital costs show up in your lab? Take time to consider what opportunities your lab may have to make improvements and explore the next steps that are right for you to optimize your operations.
