Hello, we decide to upgrade our record keeping system introducing ipads tablets in our Food processing environment (now I think maybe wasn't a good idea), now we need to do a periodical cleaning of the device and schedule a validation of that cleaning.

So, what is the best way to clean and sanitize (?) the device? We try it with alcohol and then a swap ATP test with Hygiena ultrasnap but the results are very high, then we tried with sanitize wipes and the results are still high.

 

Suggestions?

 

Thanks in advance.

Fred

We use zip lock type bags - they get replaced each day.

Now that's a good idea.

Bags are sprayed with 91% alcohol.

Glenn thank you for your suggestion, now if the bags are removed /disposed after use then there is no need to validate sanitation since the device never get in direct contact with the operator hands. I like your suggestion, will see if we can implement something similar here.

 

Thanks again.

You will presumably need to validate that you are not introducing a "source" of contamination into the Production area.

Yes, did that an it is a lot easier than trying to figure out how to clean and sanitize an ipad.

 

For maintenance we spray the ipads weekly or so with a light Ginesis cleanser with all entry points vac'ed and sealed first.

Question?:  Are you swabbing the iPad's immediately after the sanitizing step?  This could be giving you a false high reading as the reagent might be negatively affecting the result. I have found alcohol sanitizers to react with ATP swabs.  

 

 

I do like the zip lock bag idea, never occurred to put this in place.

nwilson, no I usually wait until completely dry, I swap the screen of the ipad, that is covered with a case (Otterbox) that provide waterproof protection, between 1 or 2 hours after cleaning and results are still over 100 in the hygiena device. We cannot use a plastic bag because screen lose sensibility.

I think your protective case is the issue. IME Otterbox-type coverings have many nooks and crannies, and the screen covers are a type of plastic prone to scratching, thus potentially providing harborage.

if you are in a low risk area, what (or why) would electronics even be an issue?

If you are entering data on a laptop, and not handling finished product without disposable gloves, (that you don after data entry) what is the risk?

Update, I used a swipe with a 50% clorox solution, swept around the case/screen, waited for 20 minutes and tested with ATP swap UltraSnap, the results came down to 7!, repeated the test for two days now, now I can say the case of the ipad is clean.

 

Marshall it is a food processing area that produce a RTE product, employees need to measure temps and times and enter the data to the ipad.

Fred,

 

Understood. At some point, technology gets in the way.

Then again, who sanitized that pen or paper that you were previously using?

Hi Fred,

 

I'm curious, what is yr justification for stating that an ATP reading of 100 is unsatisfactory while a reading of 71 is OK ?

 

@ Marshall, you might have also legitimately asked where the ipad goes when it's not being used ? Similarly for pens, (nibbled?) pencils, etc etc ?.

 

I'm (and Apple?) also wondering how long the ipad will survive the (isopropyl?) alcohol.


Kind Regards,

 

Charles.C

Charles, I said the result was 7, so to me that is acceptable since the device test measure "Adenosine Triphosphate, or ATP, is the energy molecule found in all living things, making it a perfect indicator when trying to determine if a surface is clean or not".

All the devices are stored in a particular table and are cleaned 30 min before go to the production area. 

Remember the Ipad is covered in a Otterbox case and I found out isopropyl 60% wasn't doing a good job as Clorox 50%.

 

At the end this is an ongoing study, we are still evaluating if: is this is the right tablet? if it can be keep clean? etc. etc, the system was just implemented so all the test are part of a "study" and will be evaluated and re-evaluated in an appropriate time frame.

 

thanks!
