pork quality standards

Conversely, DFD results from a lack of acid production in the muscle. However, the consumers could not describe the difference in the grading categories, only that the choice beef was a better eating experience. Persons using such products assume responsibility for their use in accordance with current directions of the manufacturer. One limitation to grading pork is the lack of technology that can grade at the speed of the line. Because of this, many show pigs carry the stress gene. DFD lean is more susceptible to microbial spoilage because of its higher pH (less acidity) which favors bacteria growth. U.S. An important reaction in postmortem muscle is the conversion of stored muscle sugar (glycogen) to lactic acid. Co., Dubuque, IA. August 2012. This material may be available in alternative formats. Overemphasis on carcass leanness and muscle may reduce meat quality. Color is important because it impacts consumers’ first impressions of the meat. Clearly, the consumer has spoken by consuming less pork year after year (4% decrease in the last 10 years according to the United States Department of Agriculture), but is the industry listening? Genesus pigs regularly meet Japan’s pork quality requirements, which has strict criteria for marbling, color, and pH. NPPC. US rethinks its China strategy and increased COVID-19 infections rock the industry. Soft and exudative means that the meat does not hold its shape and that moisture drips from the meat. The PSE, RSE and DFD conditions result from both heredity and animal handling practices, and can be influenced by slaughter plant procedures. While color, firmness and exudation are important considerations in evaluating lean pork quality, marbling or intramuscular fat content of the lean also is an important factor. This reduced acidity provides increased water-holding ability in the lean, tightly binding water to muscle proteins, and contributing to a firm texture. USDA. In Part 2 of this two-part series, Ryan Strobel, DVM, and Chris Sievers, DVM, with the Swine Vet Center, St. Peter, Minnesota, share implementation strategies to lower wean-to-finish mortality rates. Purdue University Cooperative Extension Service, West Lafayette, IN. These genetic screening tools have produced moderate improvements in lean pork quality in recent years. This material may be available in alternative formats. Quality variations from this ideal result in the less desirable quality extremes of pale, soft and exudative (PSE) lean, and dark, firm and dry (DFD) lean (Figures 1, 2 and 3.) Muscles destined for DFD pork have low levels of glycogen at the time of slaughter that restricts the amount of acid that can be produced, and limits pH fall. Once the North American market develops its own standards (currently being reevaluated and developed by the National Pork Board), Genesus customers will be able to collect premiums without changing their population structure or production practices. With a grading system similar to that of the beef industry, consumers could relate choice or prime pork with a positive and consistent eating experience. The user therefore, must assume full responsibility, both as to persons and as to property, for the use of these materials including any which might be covered by patent. And we’ve gotten even pickier with age. The carcass traits of leanness and muscling and the presence of the stress gene can impact the eating quality of pork. Variations in pork quality. Persons using such products assume responsibility for their use in accordance with current directions of the manufacturer. It is important that pigs exhibited in youth swine shows produce meat that has high eating quality. Marbling is the fat within the muscle, also called intramuscular fat. According to consumer research presented by Laura Bachmeir from the National Pork Board, there is a considerable amount of variation in terms of color and marbling within pork products, such as fresh pork chops, offered to consumers at the retail level. A more recently developed gene marker test using a DNA probe allows identification of non-PSS pigs carrying this gene, and there possible elimination from the animal population. Cutter, A. C., R. G. Kauffman, and L. L. Christian. 1994. 1999. https://www.ers.usda.gov/amber-waves/2016/september/us-beef-and-pork-consumption-projected-to-rebound/, In Part 2 of this two-part series, Ryan Strobel, DVM, and Chris Sievers, DVM, with the Swine Vet Center, St. Peter, Minn…, The advantages of the intradermal (ID) administration by a needle-less device are that it is less invasive, painless, sa…, Iowa's Veterinary Diagnostic Laboratory swine influenza surveillance is monitoring new and current flu strains. The current recommended cooking temperature for pork is 145 F, or 63 C (http://www.porkbeinspired.com/wp-content/uploads/2014/06/2924.pdf). They are ideal for packing plants, meat labs and judging teams. Pork lean quality can be improved by using available genetic screening tests to eliminate the porcine stress syndrome (PSS) gene from breeding stock populations, by careful handling of pigs from farm to packing plant, and by utilizing slaughter procedures which minimize the potential for adversely affecting lean quality. Likewise, since these pigs do not cope well with stress, longer-term exposure to unfavorable conditions can deplete their muscle glycogen, leading to the DFD condition. This material may be available in alternative formats. "Trichinellosis Fact Sheet – Division of Parasitic Diseases". The user therefore, must assume full responsibility, both as to persons and as to property, for the use of these materials including any which might be covered by patent. Methods to allow lean quality determinations to take place easily, accurately and at high slaughter-line speeds are under development (such as measurements of muscle pH, electrical conductivity, and light scattering and reflectance as determined by fiber optic probe). Meat with adequate marbling is less likely to be tough. Under these “normal” conditions pork lean exhibits typical red color, and muscle proteins retain acceptable water-holding ability. Note: The Official Color and Marbling Standards can be ordered from the National Pork Board by calling (515-223-2600) or by referring to the email site porkscience.org. The chemical conditions PSS produces in muscles (rapid lactic acid production and elevated temperature) strongly favors the development of PSE lean. 2000. NPPC. Persons using such products assume responsibility for their use in accordance with current directions of the manufacturer. Marbling standards, from top: 5.0, 6.0 and 10.0.
