Greetings all,

I have a question in regards to multi quat 455 as a sanitizer.

Is there a contact time related to quat? also what is the organic load that renders the quat ineffective. Range is 200-400ppm....

 

Thanks for any input,

Contact time specifications should be listed on the technical data sheet provided to you from the chemical manufacturer/supplier. 

If you are using as a sanitizer, then you should be doing a full wash/rinse before use. Sanitizers should only be used on clean surfaces. Any visible organic load will reduce sanitizer effectiveness. 

What is your product/process/washdown procedure that would cause organic matter to be left behind?

I agree with Ms Mars

 

Unless you're using quat as a boot dip, but the chemical manufacturer is the best place to get this info as no two formulas are the same


Because we always have is never an appropriate response!

the quat is being used as a sterilizer for knives in place of hot water in one specific area. we have used a Quaternary quat before in this type of situation. i just do not have any scientific evidence of reduction other than our in house stuff.......

got it.........in poultry slaughter, quat was our back up Provided the knives were rinsed prior to going into the quat solution and would be in it for X seconds prior to removal and use

If your chemical supplier cannot give you the specifics.......switch suppliers----below is from my supplier of choice 

 

Sanquat is a powerful liquid sanitizer, disinfectant, virucide and fungicide. When evaluated by accepted laboratory procedures, Sanquat provides superior germicidal and fungicidal activity far beyond that achieved with some currently available quaternary ammonium compounds. Sanquat is accepted for use in federally inspected plants without a potable water rinse at concentrations up to 200 ppm.

Dear LSB,

 

if you a exporting to the EU: Quats and their residues are under fire because they have the potential to be transferred easily up to the finished products.
