Postmortem Time on Meat Quality during Postmortem Chilled
Storage. Food Sci Anim Resour 2022; 42:816-832. [PMID: 36133632 PMCID: PMC9478973 DOI: 10.5851/kosfa.2022.e34] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 07/06/2022] [Accepted: 07/06/2022] [Indexed: 11/30/2022] Open
Abstract
To evaluate the effects of early postmortem vacuum packaging (VP) on meat quality
during postmortem chilled storage, hot-boned lamb was vacuum-packaged at 1, 6,
12, 24, and 48 h postmortem and stored around 2°C until 168 h postmortem,
with lamb packaged in plastic wrap as the control (aerobic packaging).
Intramuscular pH decline was delayed when lamb was vacuum packaged at 1, 6, and
12 h postmortem (p<0.05). The lamb vacuum-packaged at 1 h postmortem
(VP-1h group) had significantly lower shear force values and purge losses
accompanied by lower free thiol group values than other treatments during
postmortem storage and was also higher in extractable calpain-1 activity by 6 h
postmortem (p<0.05). Free thiol group concentrations were significantly
higher after VP at 6 and 12 h postmortem (p<0.05). Packaging lamb under
vacuum very early postmortem produced the lowest shear force and purge loss,
likely by slowing heat loss and muscle temperature decline, implying that lamb
quality is improved by VP when applied very early postmortem. This was at the
expense of protein oxidation, which was unrelated to other meat quality
measurements, most likely because potential contracture during hot boning
confounded its impact. Further research is required to understand the
implications of the interaction between protein oxidation, VP, and hot boning on
the acceptability of lamb.

The microbiology of beef from carcass chilling through primal storage to retail steaks. Curr Res Food Sci 2021; 4:150-162. [PMID: 33817662 PMCID: PMC8010216 DOI: 10.1016/j.crfs.2021.03.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2020] [Revised: 02/17/2021] [Accepted: 03/03/2021] [Indexed: 01/08/2023] Open
Abstract
The primary objective of this study was to investigate if alternative time-temperature carcass chilling combinations resulted in lower microbial (TVC, Enterobacteriaceae, Lactic Acid Bacteria, Pseudomonas spp. And Brochothrix thermosphacta) counts and, if achieved, would reduced levels remain throughout the beef chain. Physicochemical (temperature, pH, water activity) characteristics were also recorded. A secondary objective was to investigate the effect of primal maturation periods (2 versus 5 weeks) on the sensory properties of steaks by a trained panel for colour, odour, tenderness, and flavour. While microbial populations reduced by over 1 log10 cfu/cm2 by fast carcass chilling, these reductions were lost due to cross contamination in the boning hall and cutting room. The pH and water activity remained stable throughout the study and there was no significant difference for colour or sensory characteristics in retail steaks from the different treatment groups. It was concluded that there was no improvement to the microbial shelf-life of retail steaks from modified chilled carcasses or in the sensory shelf-life of primals which were aged for an extended period. Alternative carcass chilling regimes achieved lower bacterial counts. Cross-contamination during boning and cutting negates chilling gains. Longer maturation did not enhance beef sensory properties.

Abstract
The objective of this study was to compare the effect of current (10 °C for 10 h followed by 0 °C with a low fan speed) versus four alternative beef carcass chilling regimes, ranging from -6 °C to 0 °C and wind speeds between 1.5 and 6 m/s on the microbiology of beef carcasses. The temperature and relative humidity (RH) in the chillers, the carcass core and surface temperature, pH, water activity (aw) and carcass weight (drip) loss were recorded. Bacterial concentrations (total viable counts (TVC), total Enterobacteriaceae counts (TEC), Pseudomonas spp., lactic acid bacteria (LAB) and Brochothrix thermosphacta) were also monitored. Similar pH, aw and drip loss (2%) values were obtained regardless of chilling regime. For the most part, bacterial concentrations were also similar and, where statistically significant (P < 0.05) counts occurred, the reductions were low (≤1 log10 cfu/cm2). It was concluded that the current chilling regime was as effective as the tested alternatives in terms of the bacterial quality of the carcasses.

Abstract
Each year in Europe, meat is associated with 2.3 million foodborne illnesses, with a high contribution from beef meat. Many of these illnesses are attributed to pathogenic bacterial contamination and inadequate operations leading to growth and/or insufficient inactivation occurring along the whole farm-to-fork chain. To ensure consumer health, decision-making processes in food safety rely on Quantitative Microbiological Risk Assessment (QMRA) with many applications in recent decades. The present study aims to conduct a critical analysis of beef QMRAs and to identify future challenges. A systematic approach, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, was used to collate beef QMRA models, identify steps of the farm-to-fork chain considered, and analyze inputs and outputs included as well as modelling methods. A total of 2343 articles were collected and 67 were selected. These studies focused mainly on western countries and considered Escherichia coli (EHEC) and Salmonella spp. pathogens. Future challenges were identified and included the need of whole-chain assessments, centralization of data collection processes, and improvement of model interoperability through harmonization. The present analysis can serve as a source of data and information to inform QMRA framework for beef meat and will help the scientific community and food safety authorities to identify specific monitoring and research needs.

Abstract
Clostridium estertheticum is a psychrotolerant, gram-positive, motile, anaerobic, spore-forming, rod-shaped bacteria that causes blown pack spoilage (BPS). Spoilage occurs in vacuum-packed meat without temperature abuse. Having been reported in the last 30 years in several countries, BPS by Cl. estertheticum is a major issue around the world and presents a huge economic impact on the meat industry. Despite being an important spoilage microorganism, studies on Cl. estertheticum are challenged by numerous aspects. These include, lack or poor growth in laboratory media, long culturing periods, and unpredictable isolation on the media. These factors hamper the detection of Cl. estertheticum before occurrence of BPS, which further undermines efforts to prevent the occurrence of BPS. Nevertheless, considerable developments have taken place with regard to culture-independent methods. Although information on Cl. estertheticum is available, it is limited and remains highly fragmented. Therefore, this review collates the available information and discusses relevant aspects of Cl. estertheticum as a specific spoilage organism of BPS in vacuum-packed meat.

Abstract
Psychrophilic and psychrotolerant clostridia (n = 110) were isolated from vacuum-packed meat (beef and lamb), fresh venison and from skin and fecal samples of wild boars. They were identified to species level using MALDI-TOF MS, sequence and phylogeny analysis of the 16S rRNA and species specific multiplex qPCR. The results of all three methods were concordant. The majority of isolates were identified as C. tagluense-like Group I (n = 34) and Group II (n = 42). Thirty-five isolates could be identified to species level as follows: C. estertheticum (n = 15), C. frigoriphilum (n = 13), C. frigidicarnis (n = 1) and C. bowmanii (n = 5). This is the first report of detection and identification of C. frigoriphilum and C. tagluense-like Group II as causative agents of blown pack spoilage of beef. The species specific multiplex qPCR developed in this study could be applied to identify and to quantify the Clostridium species described above in suspicious meat juice samples.
