Dear qfb-x,
Product/process unstated but I presume yr situation requires either a high risk or high care area production area / contracted laundry.
I noticed one previous related comment, there may be others -
Food grade laundries usually 'sterilise' the clothing, this should also be validated by the laundry itself. Spot checks can be done for temperature using 'Thermax strips'

From the BRC text 7.4.4, appears that a justification for any claimed "commercial sterility" will be required.
In the case you mention, maybe will need some data. And, just as a suggestion,can try this post -

Note that additional factors are involved, eg laundry auditing or certification.
