~~No lab is using a residential fridge for experimentation. You cannot adequately control the temperature. The infectious materials tape is a joke and distinguishing marker.~~

ETA: yes, I made an ignorant comment. My apologies and thanks for the info, everyone!

 My friend did QC for a FOOD beverage company.  They had industrial fridges for legal tests, but they also simulated real use.  

That these are 3 identical milk, locked in identical ways leads me to think that this is a "real world test".  In my friend's case they'd take product out and put it into a real world situation (sitting in the back of the car for 20 minutes well over legally safe temp to simulate a drive home from the market) in order to help formulate a best by date.  Often they will use different fridges like dorm fridges or garage fridges to simulate.

In short they purposely take product and do "illegal" things by food saftey standards.  The food is not actually consumable because they are trying to grow bacteria.
