9 C.F.R. § 381.67
The maximum number of birds to be inspected by each inspector per minute under the traditional inspection procedure for the different young chicken and squab slaughter line configurations are specified in the following table. These maximum rates will not be exceeded. The inspector in charge will be responsible for reducing production line rates where in the inspector's judgment the prescribed inspection procedure cannot be adequately performed within the time available, either because the birds are not presented by the official establishment in such a manner that the carcasses, including both internal and external surfaces and all organs, are readily accessible for inspection, or because the health conditions of a particular flock dictate a need for a more extended inspection procedure. The standards in 381.170(a) of this part specify which classes of birds constitute young chickens and squabs. Section 381.76(b) specifies when either the traditional inspection procedure or the modified traditional inspection procedure can or must be used.
