D-1 PACKAGING

 Product shall be filled into pouches, processed and each pouch placed into a carton in 

accordance with MIL-PRF-44073, Packaging of Food in Flexible Pouches, Type II. 

D-2 LABELING

permanent black ink or any other contrasting color, which is free of carcinogenic elements. 

Prior to thermal processing of the pouches, the product name, lot number and filling 

equipment number shall be applied. All other marking may be applied before or after thermal 

processing. As an alternate method, a pre-printed self-adhering 0.002 inch thick clear 

polyester label printed with indelible contrasting color ink may be used. 

Note: The font tested by Natick was Microsoft Helvetica. The font used shall be similarly 

clear/easy to read as Helvetica. The recommended font sizes are as follows: 22 for the 

product name, 14 for “yield” and “to heat in water.” If an additional note is required on the 

label, such as “fluff before serving,” it should also be in font size 14. All other information 

should be in font size 9.

(5) Pouch code includes: 1/ 

 Lot Number 

 Filling equipment identification number 

 Retort identification number 

 Retort cook number 

(6) Official establishment number (for example, EST 38) 

(7) USDA official inspection legend for the packer’s plant 

1/ The lot number shall be expressed as a four digit Julian code. The first digit shall indicate 

the year of production and the next three digits shall indicate the day of the year (Example, 

12 October 2005 would be coded as 5285). The Julian code shall represent the day the 

product was packaged into the pouch and processed. Sub-lotting (when used) shall be

represented by an alpha character immediately following the four digit Julian code. 

Following the four digit Julian code and the alpha character (when used), the other required 

code information shall be printed in the sequence as listed above. 

TO HEAT IN WATER: Submerge unopened pouch in water. Bring water to a 

boil. Simmer gently [cite appropriate time] minutes. Avoid overheating (pouch 

shows evidence of bulging). 

WARNING: Do not heat pouch in oven. 

TO TRANSPORT AFTER HEATING: Insert pouch back into carton or empty pouch into an insulated food container to 

protect during transport.

CAUTION: Use care when opening as pressure may have been generated within the pouch. 

TO OPEN: Open at tear notch or cut with a clean knife. 

Note: The number of portions and the heating time will be different, depending on the net 

weight of the pouch. These requirements will be determined during production. 

 B. Cartons. Each carton shall be correctly and legibly labeled with the product name. 

Commonly used abbreviations may be used when authorized by the inspection agency.

SECTION E INSPECTION AND ACCEPTANCE

The following quality assurance criteria, utilizing ANSI/ASQC Z1.4-1993, Sampling 

Procedures and Tables for Inspection by Attributes, are required. Unless otherwise specified, 

Single Sampling Plans indicated in ANSI/ASQC Z1.4-1993 will be utilized. When required,

the manufacturer shall provide the certificate(s) of conformance to the appropriate inspection 

activity. Certificate(s) of conformance not provided shall be cause for rejection of the lot. 

 

 A. Definitions. 

 (1) Critical defect. A critical defect is a defect that judgment and experience indicate 

would result in hazardous or unsafe conditions for individuals using, maintaining, or 

depending on the item; or a defect that judgment and experience indicate is likely to prevent 

the performance of the major end item, i.e., the consumption of the ration. 

 (2) Major defect. A major defect is a defect, other than critical, that is likely to result 

in failure, or to reduce materially the usability of the unit of product for its intended purpose. 

 (3) Minor defect. A minor defect is a defect that is not likely to reduce materially the 

usability of the unit of product for its intended purpose, or is a departure from established 

standards having little bearing on the effective use or operation of the unit. 

 B. Classification of inspections. The inspection requirements specified herein are classified 

as follows: 

(1) Product standard inspection. The first article or product demonstration model shall 

be inspected in accordance with the provisions of this document and evaluated for overall 

appearance and palatability. Any failure to conform to the performance requirements or any 

appearance or palatability failure, shall be cause for rejection of the lot. The approved first 

article or product demonstration model shall be used as the product standard for periodic 

review evaluations. All food components that are inspected by the USDA shall be subject to 

periodic review sampling and evaluation. The USDA shall select sample units during 

production of contracts and submit them to the following address for evaluation: 

US Army Research, Development and Engineering Command 

Natick Soldier Center 

AMSRD-NSC-CF-F 

15 Kansas Street 

Natick, MA 01760-5018 

One lot shall be randomly selected during each calendar month of production. 

Two (2) sample units of each item produced shall be randomly selected from that one 

production lot. The two (2) sample units shall be shipped to Natick within five working days 

from the end of the production month and upon completion of all USDA inspection 

requirements. The sample units will be evaluated for the characteristics of appearance, odor, 

flavor, texture and overall quality.

 B. Methods of inspection. 

(1) Commercial sterility. Commercial sterility shall be verified in accordance with 

USDA/FSIS regulations. 

 (2) Shelf life. The contractor shall provide a certificate of conformance that the 

product has a 36 month shelf life when stored at 80o

F. Government verification may include 

storage for 6 months at 100oF or 36 months at 80oF. Upon completion of either storage 

period, the product will be subjected to a sensory evaluation panel for appearance and 

palatability and must receive an overall score of 5 or higher based on a 9 point hedonic scale 

to be considered acceptable. 

 (3) Net weight. The net weight of the filled and sealed pouch shall be determined by 

weighing each sample unit on a suitable scale tared with a representative empty pouch. 

Results shall be reported to the nearest 1 ounce (0.03 kilogram). 

(4) Drained weight. The pouch contents shall be poured into a flat-bottom container. 

A minimum of three times the pouch's volume of not less than 140o

F water shall be added to 

the container so as to cover the contents. The contents and water shall be gently agitated so as 

to liquefy rendered fat without breaking the ham chunks. The contents shall then be poured 

into a U.S. Standard 1/4 inch sieve in a manner that will distribute the product over the sieve 

without breaking the ham chunks. The sieve area shall be such that the distributed product 

does not completely cover all the openings of the sieve. The sieve shall be tilted at such an 

angle so as to assure complete drainage of all liquid from the product. The product shall be 

drained for 2 minutes before determining the drained weight. Determine the drained weight 

by subtracting the sieve tare weight from the gross weight. The drained weight shall be 

reported to the nearest 0.5 ounce (0.01 kilogram).

(OMA) of AOAC International. 

Test Method Number

Fat 985.15 

Salt 935.47 

Test results shall be reported to the nearest 0.1 percent. Verification will be conducted 

through actual testing by a Government laboratory. Any result not conforming to the 

analytical requirements shall be cause for rejection of the lot.
