Hello all,

 

For ATP testing, the guidelines show that only equipment with food contact needs to be checked for sanitation.

 

I only have one machine that bags, I'll include the conveyor, interior tunnel and exit.

Also the tables where we prepare the product.

 

Are you including additional points, for example Walls, Floors etc?

 

Thanks in advance.

We use ATP on food surfaces only. We do Listeria testing on a rotating series of non-food contact services, like drains, foot petals, door frames and wall seams.

Hi, CaliforniaFS;

 

What guidelines do you mean?

"Food contact surfaces" are based on risk assessment.  Doors, walls, ceilings, piping, cordage, hoses, etc. may very well be a food contact surface as logic flows, gloved hands are a food contact surface and may come into contact with these surfaces or possibly contaminate through condensate.

 Doors, walls, ceilings, ..........., etc. are not food contact surfaces

Hi CaliforniaFS

 

Would be doing visual inspections and periodic environmental micro swabs for things like walls and floors. Depending on your products TVC, Entero, Y&M plus pathogens (Salmonella/Listeria) again depending on your product.

 

Regards,

 

Tony

Hi, Tony;

 

No, not food contact directly of course.  I'll illustrate with my current situation;

We have a gantry system in our chill room connected to a tank of boiling water for cooking.  This gantry (and bridge) also runs above the chill tanks.  Given the very moist environment in this room condensate will form.  Condensate will and has dropped into the chill tanks containing rte product, and has been observed by auditors.  What has saved us from a critical is the fact that this system is on our SSOP for a daily cleaning and proofing with ATP and regular micro work up.

I hope that clarified my reasoning in the OP.
