Environmental Monitoring Program

More food facilities are creating and upgrading their environmental monitoring programs (EMP) due to an increasing emphasis from government agencies on locating and controlling food hazards and contaminants.

How Often Do You See Random Microbial Spikes?

One bacterium can multiply to more than 30,000 in five hours and more than 16 million in eight hours. If these bacteria then create a biofilm, standard sanitation chemicals may not remove it.

Are All ATP Luminometers Created Equal?

If contamination levels are high or sanitation procedures are inadequate, microorganisms may grow and contaminate food products leading to a foodborne illness outbreak. This article covers how to build and execute an EMP, when to conduct microbial and ATP testing, and enumerates the advantages of in-house environmental testing over 3rd party testing.

Are All ATP Luminometers Created Equal?

Selecting a quality luminometer and tests is the only way to understand if sanitation procedures are truly effective. Implementing the next level of ATP analysis will bring your product to the next level of hygiene, mitigate the inherent risks of food safety, and protect your family and children from preventable hazards.
