Origin Processing plant, exporter/seller's Process

a) Farm

The process and handling that is carried out in the collection establishment consists of all the eggs destined for the processing and packaging of eggs for table, it is collected from the houses of the laying hens, they are washed, disinfected, classified according to their quality, packed and labeled under the continuous supervision of the USDA at the egg processing establishment.


The process of washing and sanitizing (disinfecting) the eggs is carried out in the processing / collection facility, protocol of its origin, under the continuous supervision of the USDA, before the eggs are certified and, in this way, it is guaranteed about disinfecting eggs on the farm.


When egg producers become interested in exporting eggs to Mexico, they shall take into account the following:

  • Approach USDA to Request Authorization.

  • The Egg Safety Rule became effective on July 9th 2010 for egg producers with 3,000 laying hens or more. In accordance to the requirements of this rule, egg producers are required to implement food safety guidelines to control risks related to harmful insects, rodents or other hazards; to purchase chicks and hens from suppliers maintaining Salmonella control in their farms; and to comply with the sampling, cleaning and refrigeration to prevent Salmonella before the FDA.

  • Being current with their registrations, their statement and payment of taxes before the US Government –having a Tax ID or Tax Identification Number.

  • Producers shall prove before APHIS that birds are healthy and free from disease.

  • Being located in a State that is free from diseases forbidden by Mexico, e.g. Newcastle disease or avian influenza according with the zoosanitary requirement sheet and/or SENASICA combination, review periodically as this point may be modified according to the health condition of the states/counties of the United States of America.

  • Product must be processed and packaged under USDA supervision at the table egg facility using the USDA voluntary grading or voluntary continuous residence service.

  • Belonging to the NPIP or proving that at least 59 (birds) serum samples were taken and tested for Avian Influenza, using the double Agar Gel Immunodiffusion (AGID) or ELISA test in accordance to the guidelines set forth by the World Organization for Animal Health (OIE), which tested negative for Avian Influenza. To find authorized labs to perform such tests, you may click on the following link: (this document is continuously updated). 


b) Origin processing plant



  • The processing plant must approach USDA to request authorization.

  • If a processing, handling or storage plant located in the USA is interested in exporting to Mexico, it is necessary for that plant to be approved and authorized by the sanitary authority in the USA –AMS and the Local State Department.

  • Seek the authorization/granting of the plant stamp issued by USDA.

  • Comply with what is set forth in the Final Rule regarding Salmonella Enteritidis prevention in shell eggs during production and transportation:

  • To be current with its tax registration, return and payment before the US Government –having a TAX ID or Tax ID Number.

  • To be located in a State free from diseases forbidden in Mexico, e.g. Newcastle disease or Avian Influenza.

  • Establishing the written procedures/records to provide the flock identification system and procedures to maintain shell eggs identity from production through transportation, storage, processing and packaging (traceability).

  • Keeping all applicable records for one year.


c) Plant inspection stamps


  • Once USDA inspects the facilities and processes of plants which wish to be authorized for processing, handling and/or storing eggs, they will be provided an authorization number and a rubber stamp which shall be stamped on boxes and/or packages of products exported to Mexico. 

  • Packages and cases of goods shall be marked/labeled with USDA’s inspected stamp and with the establishment number (for example: PLANT-42), which is allocated to the plant where the product is produced/processed and it is the number identifying the plant.

  • The establishment number may appear on the package inside USDA’s inspected stamp as shown in the picture. It may also appear anywhere outside the package or on the package label, as long as it is present in a prominent manner, on all goods and/or cases in a legible manner and of the appropriate size ensuring good visibility and easy recognition.

Table Egg Products Stamp



d) Items that are to Be Considered for Shipment of Table Egg Loads Sanitary Provisions and Specifications


  • Eggs were disinfected in the processing plant and packaged in new cardboard cases sealed with tape, or packaged in cardboard; stacked on disinfected wooden pallets and boxes wrapped for stability with plastic film. Each case or pallet with the cartons is identified with a USDA stamp.

  • The final transport unit must be inspected by AMS for sanitation and the ability to adequately refrigerate the product during transport. Shipping is sealed prior to departure.

  • Vehicles carrying goods shall be only dedicated to food transportation. On August 27th, 1999, FSIS made effective the regulation requiring:

    Packaged eggs for consumers should be stored and transported under refrigeration without the temperature of air (surrounding them) exceeding 45 °F (7.2 °C).
    All packaged shell eggs should be labeled with a statement indicating that refrigeration is required.


Egg Backlight Inspection

In egg backlight inspection, light is used to determine egg quality. An automated piece of equipment examining large quantities is used by most egg packers to identify eggs with cracked shells or defects inside. During backlight inspection, eggs move on a conveyor and pass through mechanical sensors integrated with computer systems to separate defective eggs. Advanced technologies, using computerized cameras and sound wave technology, are also included for segregation of eggs.


e) Exporter/Seller’s Process


i. Look for a Plant Approved by USDA

Look for a processing, handling or storage plant authorized by the USDA and which is near your farm, and reach an agreement for the shipping and receiving the goods that are to be exported.  Once avian influenza monitoring has been completed, eligible table eggs will be certified with the form LPS-210S for export to Mexico and requested at the point of entry along with the certificate of free disease. All certificates (Form, LPS-210S) and disease-free statements must be signed in blue ink.

The facility must notify the USDA classifier of pending export orders, of the certification request, and provide the classifier with the following information:


• Name of the producer.

• Size of the lot to be certified.

• Flock identification and location information.

• If applicable, the date the product will arrive for processing.

• When should the product be classified and shipped.


ii. Contract a Freight Forwarder

The Freight Forwarder will manage the logistics between the client contracting him and the services involved in the transportation of goods to the destination Country.

d) Table eggs inspection procedure  in accordance with the SENASICA Commercial Guide.


Fertile Egg and Table Eggs Considerations


1. Inspection of merchandise should be carried out in such a way as to minimize damage to the shell.


a. Acceptable criteria are considered:

 I. Stains that are not blood, or feces that cover an area 0.5 cm².

II. Blood stains, which do not exceed a surface greater than 0.5 cm².


b. Dirty egg criteria are considered:

 I. An egg stained with blood, feces, or urine that exceeds 0.6 cm². Of the surface.

II. The cracked egg is not acceptable because it affects the viability of the egg. Cracks are those that are the width of a hair or more.

III. The number of dirty eggs in each tray must not exceed 10%.

IV. A sample is only taken for the laboratory when, upon physical inspection, some evidence of sanitary risk is presented and the regulatory area so determined and it must be sent to CENASA for its diagnosis at cost to the Interested Party.

Shell egg considerations


1. During physical inspection the factors of temperature, time and humidity should not have a detrimental effect on the safety and suitability of the eggs.


2. When the dish egg has been subjected to refrigeration, the cold chain must be maintained throughout the process, including their inspection.


Phase I. Document Review:

1. The user must capture the data and attach the documents of the merchandise to be imported in accordance with what is requested in the Combination of Zoosanitary Requirements corresponding to the country of origin and provenance, as well as in the special letters issued by the DGSA when applicable.


Phase II. Physical inspection:


1. 100% of the containers and / or pallets containing the merchandise must be unloaded in the inspection area and the pallets must be placed so that they allow the path of official personnel.


2. The cargo must be well stowed, so that the necessary movements can be carried out to unload and inspect the merchandise.


3. Containers and / or pallets must be presented clean.


4. The officer verifies that the original strapping is presented intact at the opening (when so indicated in the requirements module).


5. Official staff corroborate that the eggs were packed in new washed cardboard or plastic boxes.


6. It is verified that 100% of the boxes are well identified by means of labels or stamps that contain the information referring to the shipment, for example, but not limited to: number of official zoosanitary certificate, number of incubator or producer plant, name of the farm, lot number (s) and in accordance with compliance with the fractions of Art. 89 of the LFSA. It must be verified that the identification present in the boxes corresponds to what is declared in the documentation of the merchandise to be imported.


7. The trays should not be shaken, the eggs should not be removed from their place except when a drained or stained egg is observed, to verify how far the stain reaches and determine the number of “dirty” eggs per box.


8. The visual inspection of the egg, which is recommended to verify its compliance with the animal health requirements established for this type of merchandise, includes:


a. Open the box when required by the requirements combination.

b. Select the boxes to be checked according to Table 1 of this procedure.

c. Choose the boxes randomly.

d. Check the eggs preferably on table surfaces and in places with a temperature similar to that in which the eggs should be kept, to avoid condensation water forming on them in hot places.

e. Check without the presence of drafts.

f. Check all the trays of the selected boxes.


Table 1. Determination of the sample size of the boxes to be inspected




The classification of defects to approve or reject the importation of products will be applied according to the following table:





1. If more than 10% of dirty egg is found per sampled tray, the revision is increased to 50% more than the boxes inspected; if the pattern repeats or increases, reject the lot.


Opinion of the procedure:


1. Accept that the process continues if there was no obstacle in the physical inspection of the merchandise. Place the strap (s) when indicated in the requirements module (fertile egg and SPF).

2. Refusal of the procedure when:

a. Does not comply with any of the established Zoosanitary Requirements, indicating in the refusal the specific reasons to proceed with the modification of the procedure if it is appropriate or the definitive rejection of the shipment.

b. The presence of blood, excrement and / or feathers or small feathers is detected in the amounts described in Table 2.
