Per module 11 of the SQF Code:
11.3.8 Laundry
What the SQF Code says
11.3.8.1 Provision shall be made for the laundering and storage of clothing worn by staff engaged in high risk
processes and for staff engaged in processing operations in which clothing can be heavily soiled.
11.3.8 Implementation Guidance
What does it mean?
In high risk areas or facilities where clothing can be heavily soiled, provision must be made for the
laundering of uniforms.
What do I have to do?
Laundering of uniforms can be on-site or off-site, but must ensure that clean uniforms are available for staff at
shift commencement, or when uniforms become soiled.
Change rooms (refer to 11.3.7) are required when clean, laundered uniforms are brought on site and staff
have to change into them. Restrooms are not adequate to be used as change rooms for this purpose.
11.3.8 Auditing Guidance
This element will be audited as part of each site audit through observation and interview with
operational staff. Evidence may include:
Provision is made for laundering of protective clothing worn by staff;
Provision is made for laundering of uniforms of staff working in high risk areas;
Sufficient numbers of clean, laundered uniforms are available.
Expect any auditor to want validation and verification of uniform sanitation process with whichever option (intern/external) you choose. I recommend using a contracted company for laundry services (you mention Cintas, that's who we use and we have been happy with them).
