black spots in pork meat

It was able to grow and produce blackening at 5, 25, and 30 °C and with salt concentrations of 2 and 5% at 25 °C and with 2% NaCl at 5 °C in culture media. When comparing with PB1 and PB5 performances, we observed that the pigment gives Ps. Fingerprints of other strains showed only some similarities. Overall, however, higher spray washing pressures (20.68 or 27.58 bar) were more effective (P < 0.05) than the lower spray washing pressures (2.76 or 13.79 bar) in removing fecal material from and reducing bacterial numbers on adipose tissue samples. HIDE COMMENTS. Was it anything dangerous, or are they just wuss'? We also identified Ps. Such strains have not been described in the literature before. Closely related strains produced almost identical fingerprints. norepinephrine was produced. Similar findings were noted with theophylline where 100 μ units/ml of insulin inhibited about 45% of the glycerol release caused by a mideffective concentration of theophylline. Addition of tyrosine or its precursors to this basis-medium allowed to distinguish between the melanin-forming and melanin-free strains within 16 hours. Journal of Agricultural and Food Chemistry. Gloucestershire Old Spots. Should I be concerned? If it was literally just black on top of the skin might be some sort of ink press used by the farmer to indicate something? If there is a “use by” date printed on the package, make sure you freeze or cook the pork before this date passes. Although both ortho-pyrocatechase (OP) and meta-pyrocatechase (MP) were found in CB1-9 and R5-3, MP activity was 20- to 50-fold higher in R5-3 cells grown on 4-methylbenzoate than in the same cells grown on benzene. The aim of this study was to identify the microorganisms involved in dry-cured Iberian ham black spot spoilage and to study the conditions affecting their growth. Show 11 Comments Comments. DOPA and DOPA-chrome are not present in the culture extracts. Meat quality factors, packaging and cooking techniques make a noticeable difference in the cooked appearance of pork patties (see Ground Pork Cooked Color Guide). P. putida strains throughout their natural history. black with different bacterial phytopathogens, we demonstrated that Ps. You can get regular meat from the foxes and wolves near Olvia, since they spawn like crazy. Many breeders in central Indiana specialized in breeding Spotted hogs through the years. Those eggs hatch and the parasite grows inside of snails. Very popular with chefs, its quality owes to the layer of fat on its meat which bastes the meat as it cooks, keeping the pork moist and tender with long in the mouth flavour. Subcutaneous and perirenal adipose samples were assayed for glucose-6-phosphate dehydrogenase, 6-phospho- gluconate dehydrogenase, NADP-isocitrate de- hydrogenase (ICDH), fatty acid synthetase (FAS) and acetyl CoA carboxylase. available glucose and consequent effects on the medium's pH. I say pork is pork and my dad a retired butcher agrees!! I was prepping a pork butt and noticed a dark purplish spot. The variation in removal of fecal material from, and in reduction of microbiological contamination on, different sizes of surface areas of fecal material contamination and with different chain-speeds was minor under the conditions of the study. glycinea B076 and Clavibacter michiganensis subsp. Restriction enzyme digests of the single 57-kilobase (kb) plasmid in R5-3 and of the single 33-kb plasmid in CB1-9 were similar, but also indicated rearrangement of plasmid DNA. 1.25, 1.875, or 2.50 cm2) with a bovine fecal paste containing a culture of streptomycin-resistant Escherichia coli ATCC 11370. A more cringe-worthy possibility I'm adding below. Menu. Mexico. Surface pH of Fresh Beef as a Parameter To Validate Effectiveness of Lactic Acid Treatment against E...

On agar plates containing glucose, the This extension circular describes the nine-point body condition scoring system, relationship between body condition and productivity of the cow herd, and use of body condition as a management tool to develop and, Access scientific knowledge from anywhere. The presence of black spots on dry-cured Iberian ham surface is an alteration related to microbial population. You know how many paracites and worms are in that meat.cook all of your food and you will be just fine.i have the same problem with the black spots around some of the local ponds i … Subcutaneous adipose samples with intact fascia from the surfaces of briskets (obtained within 15 min postmortem) were inoculated on different sizes of surface areas (0, 0.3125, 0,625, Effects of high-pressure treatment (100MPa to 600MPa) on lipid oxidation and composition of fatty acids in yak body fat at 4°C and 15°C were investigated for up to 20days storage. At surface pH values of 3.8 and 3.65, lactic acid reduced E. coli O157:H7 on lean and adipose tissues by approximately 0.3 and 0.42 log CFU/cm2, respectively. Several microbial strains were isolated from Iberian hams spoiled with black spots at the beginning of post-salting stage. The lipolytic effect of ACTH was also inhibited by insulin and this inhibition appeared to be greater than that seen when norepinephrine or theophylline was used as the lipolytic agent. monitor nutritional programs. Today, pork is cured for flavor, and though the method lengthens cured pork’s storage life, most cured pork must be kept refrigerated. black a higher tolerance to oxidative stress and UV radiation exposure. Pseudomonas fluorescens biovar V-1 was most frequently isolated (24%); it either predominated or was present in all types of samples. Pseudomonas putida A and B were evident in environmental rather than in food samples. (In other places, carnitas generally refers to fried pork meat without skin or a stew-like dish made from it.) Comments are closed HIDE COMMENTS. Prof. E. F. Pernot writes that during the butchering season of the year the Oregon Experiment Station frequently receives specimens of pork that present an unmarketable appearance. Among strains, light Sussex incorporated the lowest (P < 0.05) concentration of 18:3n-3 in the hepatic tissue. Pork is the culinary name for meat from the pig. black could inhibit the growth of Xanthomonas vesicatoria Bv5-4a, Pseudomonas syringae pv. I've seen spoiled meat/beef before and it's brown, however this was very dark and black and was very small. I went to the wet market today, and there was pork with black spots on the skin, in which the butcher removed. On the basis of these results we recommend to apply these simple, fast and cheap methods for identification and discrimination of new environmental and clinical isolates of the species R. aquatilis. are proved to be without influence on the pigment production. New posts New media New articles New media comments New article comments New resources New profile posts Latest activity. HIDE COMMENTS. He said the loins and hams were covered with dark red spots. - Derek Cooper on the BBC Radio 4 Food Programme. It is concluded that a higher-pressure treatment is important in catalyzing lipid oxidation and the evolution of fatty acids in pressure-treated yak body fat. However, when the bacteria were incubated in these media The pig's left side of the face was covered with it almost looking like scabs. mY WIFE swears there is a white and dark meat in pork. 4. The main objective of this study was to determine whether surface pH after application of diluted. putida A and B (11%); Ps. Grass Fed Meat & Poultry; Gloucester Old Spot Pork; Gloucester Old Spot Pork "Once you try Gloucestershire Old Spots pork, you'll turn your back on the tasteless, dried up, intensively reared pork forever." EFFECTS OF DIETARY ENERGY AND BIOLOGICAL TYPE ON LIPOGENIC-RELATED ENZYMES IN BEEF STEERS1, 2, Saturated Hydrocarbons in Fatty Tissue of Beef Heart. The Spotted swine breed is characterized by large, black-and-white spots. A computer-aided technique was used to identify most of the 445 fluorescent strains. PCR patterns of five nitrogen-fixing soil bacterial strains isolated from the rhizosphere of wheat in the vicinity of Bayreuth were generated by PCR using random and repetitive (BOX, ERIC and REP) primers. Used a bottle washer to ream it out. Check the Color. I went to the wet market today, and there was pork with black spots on the skin, in which the butcher removed. New comments cannot be posted and votes cannot be cast. Separate continuous cultures of Pseudomonas putida R5-3, grown on toluene, and Pseudomonas alcaligenes C-O, grown on benzoate, were concentrated and continuously amalgamated on a ceramic bead column, which was subjected to a continuous stream of chlorobenzene vapors. There is no identity between the isolated brown pigment and authentic DOPA-melanin. Forums. Sign In or Register. By using the available of polyunsaturated fatty acids, and C22:6 decreased significantly. He said it was moles on the skin of the pig, but I didn't really understand him since he explained it to me in Chinese. The form of myoglobin found in the patty meat at the time of cooking also has an affect on cooked internal color (Lien et al., 2002b). beneficial interaction between a strain of Pseudomonas putida and the fungus Saccharomyces cerevisiae was identified. At surface pH values of 3.0 and 2.75, lactic acid reduced E. coli O157:H7 on surfaces of lean and adipose tissues by approximately 1.60 and 1.54 log CFU/cm2, respectively. S. cerevisiae deletion library, yeast mutants that were unable to mediate this beneficial interaction were identified. If the pork chops are gray or brown, they have started to spoil. A friend was calling to ask my advice. Black discolouration of pork and beef adipose tissue is a relatively rare but quite eye-catching phenomenon and an obvious sign of advanced spoilage of the affected meat surfaces. My husband bought some pork chops yesterday, we had some yesterday and today he cooked the remaining ones. If there is no date listed or only a “sell by” date marked, try to cook or freeze the product within five days of your purchase. The melanin-forming strains of the species Pseudomonas aeruginosa are not regarded as variants containing a tyrosinase but as mutants with a genetic defect of homogentisicase in analogy to the alcaptonuria in metabolic diseases of men. fluorescens III-1 in spoiled fish. At 1 m unit/ml complete inhibition of the glycerol release by as much as 5 × 10−7 M, Implanting at an alternate location (in the muscle or fat pad at the base of the ear) or crushing the pellets did not appear to cause side effects or adversely affect animal performance. Top view on black stone table. Microbiological and visual evaluations were performed to compare the efficacy of hand trimming, spray washing, or a combination of treatments, in the removal of bacteria and fecal material from beef adipose tissue. Summary The influence of beef and turkey insulin was studied on the incorporation of labelled carbon from u-14C-glucose into glycogen of diaphragm and fat pad and into lipids of fat pads from rats. mY WIFE swears there is a white and dark meat in pork. At concentrations of 100 μ units/ml, beef insulin was capable of blocking by about 50% the glycerol release produced by a mideffective concentration of norepinephrine. P. alcaligenes C-0 grew on benzoate and 3-chlorobenzoate but not on toluene, P. putida R5-3 grew on benzoate and toluene but not on 3-chlorobenzoate, and neither strain grew on chlorobenzene or 1,4-dichlorobenzene; however, the recombinant P. putida CB1-9 grew on all of these substrates. Please settle this once and for all. He tenderised them and fried them, they were cooked in the middle and the juices ran clear. Pig meat is cut and packaged in several forms, including pork chops, sausages, ribs, tenderloins and hams. Enzyme activities were more active in the subcutaneous than perirenal adipose tissue of both types of cattle. aeruginosa (0.7%). Now the rest of the meat I looked at/smelled and it was fine. The circumstances of isolation of the responsible bacteria point to a spoilage association or biofilm in which the yeasts possibly promote bacterial growth. A large, predominately white pig with a few black spots, the Gloucestershire Old Spots has huge lopped ears that droop over its face and a long, slightly arched back. The Gloucestershire Old Spots (also "Gloucester, Gloucester Old Spot, Gloucestershire Old Spot" or simply "Old Spots") is an English breed of pig which is predominantly white with black spots.It is named after the county of Gloucestershire.The Gloucestershire Old Spots pig is known for its docility, intelligence, and prolificity. Based on the conditions of this study, there was no difference between spray treatments at 38 or 60°C, but 4.5% lactic acid solution reduced pathogens more effectively ( P ≤ 0.05) than did 2% lactic acid solution. By using our Services or clicking I agree, you agree to our use of cookies. high, it is likely that the presence of fungi has had profound beneficial effects on the physiology and survival of certain One of the farms connect directly to Velia has a chicken meat node, however alot of recipes call for regular meat not poultry meat. Probably this effect may be caused by accumulated homogentisic acid similar to the inhibition of tryptophan-pyrrolase by hydroquinone. And the meat wasn't past due or anything and it went STRAIGHT into the freezer. that the beneficial effect on bacterial physiology and survival was mediated by the ability of the fungus to metabolize the Unidentified strains accounted for 10.6% of the flora, many resembling Ps. Fresh pork chops are light pink to white. Could be moles/freckles like /u/iso700c said. Arch. What's new. Of 182 various foodstuffs and environmental samples examined, 86% had microflora containing fluorescent Pseudomonas in differing proportions. Glycine, L-arginine, L-glutamine and L-monosodium glutamate were the amino acids that significantly decreased the L values and increased the browning scores in comminuted meat which was mixed with 40 gkg−1 NaCl and 20 gkg−1D-(+)-, glucose and inoculated with Carnimonas nigrificans CTCBS1T. By all primers used it was clearly shown that the natural isolates belong to the species R. aquatilis. The TASTY FLESH of EVERY animal shall be discussed here. Avoid pork that looks dry, shows dark spots on either the meat or the fat, or is sitting in liquid. That there was a black...small spot on the ground beef. The Pietrain is a easily recognized meat pig breed that is white in color with black spots. Dietary 18: 3n-3 resulted in an increase (P < 0.001) in n-3 fatty acid content of all tissues. Melanin production does not occur in tyrosineless ammoniumgluconate medium. So, if your meat turns to the dark side, just give it a sniff. Only one-third of the pork produced each year is sold fresh. They extended right through the grain of the meat. Comments are closed HIDE COMMENTS. If they have a sour or unpleasant odor, throw them out. Home. The RAPD and rep-APD characterization of the strains studied here is in full agreement with their taxonomical analysis performed by other molecular methods such as micro- and macro-RFLP fingerprinting, ribotyping and 16S rDNA sequencing. Today, Spots are known for their feed efficiency, rate of gain and carcass quality. (ABSTRACT TRUNCATED AT 250 WORDS). of glucose, they lost viability rapidly during stationary phase. By these analyses, it was possible also to show that the clinical R. aquatilis strains form another, third group. It can be identified by the presence of small black spots, usually about the size of a pin head, in the skin, the fins, the musculature, and the mouth of the fish. Not sure what to advise beyond that. Some meat may also show an iridescent sheen. Turkey insulin showed an increased biological activity in comparison to beef insulin. Press question mark to learn the rest of the keyboard shortcuts. He said it was moles on the skin of the pig, but I didn't really understand him since he explained it to me in Chinese. If the pork chops are gray or brown, they have started to spoil. The samples were then spray washed with water at 35°C in a specially designed automated spray washing cabinet at pressures of 2.76, 13.79, 20.68, or 27.58 bar and at chain speeds equivalent to 100, 200, or 300 carcasses per hour (exposure times of 36, 18, or 12s). Optimum surface color of fresh meat (i.e., cherry-red for beef; dark cherry-red for lamb; grayish-pink for pork; and pale pink for veal) is highly unstable and short-lived. Uncooked pork chops can safely be refrigerated at 40 degrees Fahrenheit for up to three days, or one to two days past the sell-by date. Brown color with a putrid smell and slime are good indicators that pathogenic bacteria have also had a chance to grow and the meat may not be safe to eat. Although the word pork can also refer to cured, smoked, or processed meat, this article will focus on fresh meat. Composition analysis shows that 600MPa treatment induces a lower (p<0.05) percentage, The U.S. beef industry must provide documentation to the U.S. Department of Agriculture, Food Safety and Inspection Service (USDA-FSIS) that the antimicrobial interventions implemented or any subsequent changes in the process are effective under the actual conditions that apply in its operation. 5. HELP!!!! I do have a picture, but if the others caused cringes, this one surely would, so I will just use the link again, and not embed: The effect of NaCl concentration on browning and on the growth of Carnimonas nigrificans CTCBS1T was also evaluated. If they have a sour or unpleasant odor, throw them out. However, the Pietrain is a known carrier for the gene that causes Porcine Stress Syndrome (PSS). The dark meat usually has a couple streaks of fat in it. N-acetyl-L-cysteine, L-cysteine, potassium metabisulphite and propil-3, 4, 5-trihydroxybenzoate prevented browning at 10 and 5 gkg−1. "BLACK SPOTS ON PORK. pork; and pale pink for veal) is highly unstable and short-lived. I cooked it, and it was fine, and delicious, but some people wouldn't eat it because of the spot. When these bacteria grow, the meat turns brown, smelly, and maybe even slimy. Enzyme activities were expressed as units per milligram of adipose tissue protein and (or) per gram of adipose tissue. There was a reduction (P < 0.05) in microbiological counts on the treated samples compared with those on the unwashed and/or untrimmed inoculated (control) samples. The breed is known for its distinctive black spots, floppy ears, and ability to produce flavorful, succulent pork with generous fat and marbling. Pork is a rich source of many vitamins and minerals, including: Thiamine. Through a Tn5 mutagenesis approach, we found 2 representative clones, PB1 and PB5, that were consistently unable to produce the pigment under several growth conditions and were not altered in their in vitro probiotic traits. The bigger issue is the looks--the spots turn quite black when cooked, and I can't imagine many consumers being comfortable serving meat that looked that way. black with tryptophan supplementation. Preventing the melanin formation by growth on the tyrosineless basis-medium with addition of l-tryptophan the quinazoline pathway is employed again, which had been found inhibited during simultaneously occuring production of the brown pigment. Arbitrarily primed polymerase chain reaction, with incorporation of either radioactive or fluorescent labels, was used as a rapid and sensitive method for obtaining genomic fingerprints of strains of Lactococcus lactis. Worked, the nest came out on the brush bristles (got a packet of bottle brushes at Harbor Freight). In this study, a novel Kansas Agricultural Experiment Station Research Reports, Bollettino della Società italiana di biologia sperimentale, DM until mean pen weight averaged 340 kg and then 2.96 Meal per kilogram feed DM until slaughter. syringae B728a, P. savastanoi pv. Chlorobenzene-utilizing strains were not found in continuous cultures run at the lowest growth rate (0.05/h) or in the absence of the donor strain, P. alcaligenes C-0. HELP!!!! The Gloucestershire Old Spot (GOS) is the oldest pedigreed spotted pig in the world, dating back to 1790. michiganensis Cm9. We bought a pork roast, which looked completely normal, then even before it was cooked, while it was still completely red all the way through, there was a darker spot (a good sized one) on the top of it. Gloucestershire Old Spots. In natural environments where the concentration of glucose is We have isolated a rhizospheric pseudomonad that produced a black pigment, which is not a widespread trait within this genus. The high 18:3n-3 diet resulted in a reduction (P < 0.05) in the total lipid content of the liver tissue in all strains. The mite causing these pustules and subsequent black spots is known as Demodex fulliculorum yar suis, a very large name for such a small mite, that may be seen only by the aid of a magnifying glass. fluorescens biovar V. Although the presence of Ps. When light shines on a slice of meat, it splits into colors like a rainbow. The pork industry wants to work toward a consistent eating experience for all consumers. lundensis in spoiled meat and Ps. The Spotted swine breed is characterized by large, black-and-white spots. All melanin-forming strains are found to be remarkable by accumulating homogentisic acid followed by developing a red, later brown pigment, whereas the melanin-free strains do not concentrate homogentisic acid in detectable amounts. Even more, they have been clustered into two groups around the two ATCC strains 33071 and 33989, respectively. 400 and 600MPa treatments increase the level of thiobarbituric acid-reactive substances (TBARS) 335% and 400% (p<0.05), respectively. In order to control the incidence of the alteration temperature throughout salting and post-salting stages should be under 5 °C until salt reaches at least a concentration of 2% or water activity is reduced on the surface of dry-cured Iberian ham below 0.92. This has resulted in pork products that are more uniform in color and taste, and healthier for consumers. The pork is smoked over burning hay allowing the smoke to penetrate the meat juices resulting in a flavor quite unlike regular pork and a meat that is somewhat chewier. To read the full-text of this research, you can request a copy directly from the author. Many of these spots in the early stages contain a small amount of pus, and by careful examination a small mite will be found buried deeply in the skin. Ps. Until quite recently, Jeju Black Pigs were kept in order to dispose of human waste. Show 11 Comments Comments. Pork should be pink to pale red in color with white fat. It was developed in the UK, and later imported to the US, and proved to be a great success in the pork industry of the country. When it was inoculated in sterile pork fat tissues, grow and blackening were only detected in samples without added salt at water activity of 0.94 and 0.97. This is because meat contains iron, fat, and other compounds. adipose tissue incorporated the highest level of 18:3n-3. There are various pigments in meat compounds that can give it an iridescent or greenish cast … The mite causing these pustules and subsequent black spots is known as Demodex fulliculorum yar suis, a very large name for such a small mite, that may be seen only by the aid of a magnifying glass. Total aerobic mesophilic plate counts, streptomycin-resistant bacterial plate counts and visual scores for fecal contamination were obtained. Chloride was released in stoichiometric amounts when P. putida CB1-9 was grown on either chlorobenzene or 1,4-dichlorobenzene. Small type cattle were slaughtered when treatment mean live weights reached 440 or 489 kg while the large type cattle were slaughtered at either 614 or 670 kg live weight. The American Yorkshire is a breed of large domesticated pigs is the American version of Britain's 'Large White'. The patterns obtained by PCR fingerprinting of total DNA or of cells from fresh colonies or liquid cultures added to the PCR mixture did not differ significantly. posted by batmonkey at 6:58 PM on August 22, 2011 Black spots.

EC00-281 Body Condition Scoring Beef Cows: A Tool for Managing the Nutrition Program for Beef Herds. You can request the full-text of this article directly from the authors on ResearchGate. 5. I'm wary of the parasite-friendly nature of pork meat, so I'd probably cut out the sections of fat with the spots before cooking. fluorescens biovars I-1 and I-2 (13.9%), II-1 and II-3 (3.6%), III-1 and III-2 (8.7%), IV-2 (0.7%); Ps. Incorporation of body condition scoring as a management tool can increase the profit potential of the cow/calf enterprise. Other strains, belonging to the other subgroups of biovar V (V-2, V-4, V-5, V-6 and V-7), together represented 14.3%. While mainly known as a commercial hog, this hardy, old breed produces flavorful, lean but well-marbled meat. Fresh pork chops are light pink to white. lactic acid solution on surfaces of fresh meat can be used as a control measure indicator for the reduction of E. coli O157:H7 and Salmonella. The production of gray/black pigments has been described mainly within the P. fluorescens complex, for isolates involved in meal spoilage, The ability of insulin to inhibit the norepinephrine, theophylline and ACTH induced glycerol release from isolated fat cells was investigated. This strain was tentatively identified as Pseudomonas fluorescens by using the API 20 NE system and phylogenetic analyses based on the 16S rRNA and carA genes. Please settle this once and for all. Although it provokes important economic losses for the meat industry, the microorganisms responsible for this spoilage still remain unclear. Black spot disease is commonly observed in rock bass and other sunfish, bass, pike, perch, minnows, and other fish species. Samples (240 each) of lean and adipose beef tissues were inoculated with cocktail mixtures of Escherichia coli O157:H7 and Salmonella. New posts Search forums. Called Neascus or black grub, this tiny parasite is released into the water, in egg form, by fish-eating birds. This breed is only comparable to the Landrance pigs by size and other characteristics. The Pietrain has the ability to produce high yields of lean meat. fluorescens V-1 was often marked, other taxa predominated or were present in large quantities in some particular samples, such as Ps. Currently, the population of this breed is static. Spray treatment with lactic acid solution for 1 to 10 s reduced surface pH values of lean tissues (3 to 3.8) and adipose tissues (2.75 to 3.65). Suffice to say I'd pass on it and find a more uniform cut. © 2008-2021 ResearchGate GmbH. Except for Psg B076, this antagonism was lost for PB1 and PB5 and when performing the test for Ps. In contrast, bacteria grew poorly and were nonmucoid in such media in the absence of the fungus. Your pork should be moist and firm, while pork that has spoiled will be sticky, dry or hard. Like other forms of meat, pork contains naturally occurring bacteria that are rendered harmless when the meat is properly cleaned and prepared. The mite causing these pustules and subsequent black spots is known as Demodex fulliculorum yar suis, a very large name for such a small mite, that may be seen only by the aid of a magnifying glass. black presented several traits associated with plant-growth promoting potential with classical in vitro assays. Photo about Baked pork meat tenderloin chop. When he cut through the loin he discovered the red spots weren’t just on the surface. Pork should be pink to pale red in color with white fat. Pigs have moles and freckles too, but scabs could indicate the animal was mistreated or badly kept. Thanks! The mite causing these pustules and subsequent black spots is known as Demodex fulliculorum yar suis, a very large name for such a small mite, that may be seen only by the aid of a magnifying glass. Therefore, surface pH after spray treatment with lactic acid could be used to validate pathogen reduction. Mikrobiol. Our Heritage Pork comes from an old-world English breed. A little marbling (veins of intramuscular fat that run through the meat) is a good thing if you can find it —marbling means juicy meat. Besides, the supplementation of M9 with tryptophan inhibited the pigment production under C:N ratios of 4:1, and the addition of kojic acid reduced notably the pigment under favorable conditions. Open the package and smell the pork chops. Enzyme activities decreased or were unchanged as, Bioscience Biotechnology and Biochemistry. All rights reserved. They are often referred to as “Spots”. Besides chicharrón made from pig skin and fat, snack-food companies Barcel and Sabritas have commercialized vegetarian versions (primarily made of puffed cornmeal batter) with chile and lemon flavorings since the 1980s. The surface pH values after lactic acid treatment and the reductions of both pathogens showed a strong linear relationship; this indicates that a surface pH of 3.1 would provide at least 1-log reduction of E. coli O157:H7 and Salmonella, regardless of lactic acid application parameters.
