Breeder farm
Farms with breeder flocks that produce hatching eggs. The hatching eggs from a breeder farm are transported to a hatchery.
Chick handling materials
Handling materials used in the transport of layer day-old chicks such as chick boxes and dollies.
Continuous inspection
Continuous inspection requires that the FSIS inspector is on the premises of the egg products processing facility whenever egg breaking and certain other processing operations, including pasteurization, are occurring.
Control Area
A Control Area (an Infected Zone and Buffer Zone) has individual premises quarantine for Infected Premises, Suspect Premises, and Contact Premises and movement restrictions for At-Risk Premises and Monitored Premises.
Dry eggshells
Eggshells dried in specialized equipment such as a rotary or beltdryer to a moisture content of approximately 4 percent.
Layer day-Old chicks
Layer day-old chicks are newly hatched chicks that are usually moved from the hatchery within a day after hatching.
 The shell egg of the domesticated chicken.
Egg-handling materials
Handling materials used in the transport and storage of eggs such as plastic flats, pallets, buggies, setter trays, divider boards, etc.
An incubator used for incubating eggs from approximately 18 days until they hatch.
A commercial establishment that hatches chicks from hatching eggs. Commercial hatcheries receive hatching eggs from offsite breeder farms and produce chicks that prior to feeding and watering are shipped to pullet raising operations.
Hatching egg
An incubator used for incubating eggs from approximately 18 days until they hatch.
Inedible egg product
Dried, frozen, or liquid egg products that are unfit for human consumption.
In-line processing center
Egg processing facilities that source eggs directly through mechanical means from poultry flocks that are present on the premises.
Layer hatching egg
An egg produced by breeding birds. Chicks hatched from hatching eggs may be used for commercial egg production or to supply multiplier breeding flocks.
Low risk
It is highly unlikely that moving eggs or egg industry products will cause infection in another poultry production premises. The determination of “low risk” suggests that although not a strict requirement, additional resources to further evaluate or mitigate this risk may be considered (depending on circumstances).
Monitored breeder flock
Flocks in the Control Area that meet the following criteria: have had two 5-bird pools or two 11-bird pools tested for HPAI by RRT-PCR and found negative; traceability information is available; flock production parameters are normal and the premises biosecurity measures are acceptable to State and Federal officials; and the epidemiological assessment is complete, and indicates no dangerous contact with Infected Premises.
Movement permit
A VS Form 1-27, a State-issued permit, or other specific or general permit—customized to the specific situation—generated by the Permit Section of the Incident Command Team and issued at the discretion of Incident Command to allow the movement of egg and egg industry items under official regulatory control from a premises or a geographic area described in a quarantine order to an approved premises.
National Poultry Improvement Plan
Cooperative State-Industry-Federal program that establishes guidelines for evaluation of poultry products and poultry production relative to disease and eligibility for interstate/international trade.
Negligible risk
The likelihood of the product movement causing infection in another poultry production premises is insignificant or not worth considering. The determination of “negligible risk” suggests that allocating additional resources to mitigate this risk may not be a cost-effective use of resources.
Nest run shell egg
Eggs that have been packed as they come from the production facilities without having been washed, sized, and/or candled for quality, with the exception that some checks, dirties or obvious under-grades may have been removed.
Nest run farms (offline)
Farms producing nest run eggs as their final product and transporting them to processing.
Non-pasteurized liquid egg
Shell eggs that have been washed, sanitized, and broken and converted to liquid egg which has not been subjected to pasteurization.
Off-line processing centers
Egg processing facilities that do not have poultry on the premises.
The process of subjecting each particle of egg product to heat in order to destroy harmful viable microorganisms, including highly pathogenic avian influenza virus.
Pasteurized liquid egg product
Any liquid egg product pasteurized according to Title 9 Code of Federal Regulations (CFR) Part 590 and bearing the USDA FSIS mark of inspection. These are products not containing ingredients added after pasteurization.
Pullet Farm
Pullet farm is a commercial establishment dedicated for raising chicks from 1-2 days of age to about 16 to 18 weeks of age when they are moved onto layer facilities for egg production.
An incubator used for incubating chicken eggs for approximately 18 days. (As opposed to a hatcher used to incubate eggs after they have been in a setter).
Voluntary Preparedness Components
Voluntary Preparedness Components facilitate business continuity by enrolling premises in specific biosecurity practices and audits designed to expedite compliance for movement of eggs and egg industry products from participating premises within an avian influenza Control Area.
Washed and sanitized shell egg
Eggs that have been washed and sanitized according to protocols equivalent to those that are specified in 7 CFR 56 and sanitized with a chlorine concentration of 100–200 ppm.
