Ambitious in its historical scope and its broad range of topics,Tied to the Great Packing Machinetells the dramatic story of meatpacking's enormous effects on the economics, culture, and environment of the Midwest over the past century and a half. Wilson Warren situates the history of the industry in both its urban and its rural settings-moving from the huge stockyards of Chicago and Kansas City to today's smaller meatpacking communities-and thus presents a complete portrayal of meatpacking's place within the larger agro-industrial landscape.Writing from the vantage point of twenty-five years of extensive research, Warren analyzes the evolution of the packing industry from its early period, dominated by the big terminal markets, through the development of new marketing and technical innovations that transformed the ways animals were gathered, slaughtered, and processed and the final products were distributed. In addition, he concentrates on such cultural impacts as ethnic and racial variations, labor unions, gender issues, and changes in Americans' attitudes toward the ethics of animal slaughter and patterns of meat consumption and such environmental problems as site-point pollution and microbe contamination, ending with a stimulating discussion of the future of American meatpacking.Providing an excellent and well-referenced analysis within a regional and temporal framework that ensures a fresh perspective,Tied to the Great Packing Machineis a dynamic narrative that contributes to a fuller understanding of the historical context and contemporary concerns of an extremely important industry.

This review describes the recent advances in the production and application of cellulose nanomaterials. Cellulose nanomaterials (CNMs), especially cellulose nanocrystals and cellulose nanofibers, can be produced using different preparation processes resulting in materials with unique structures and physicochemical properties that are exploited in different fields such as, biomedical, sensors, in wastewater treatment, paper and board/packaging industry. These materials possess attractive properties such as large surface area, high tensile strength and stiffness, surface tailor-ability via hydroxyl groups and are renewable. This has been a driving force to produce these materials in industrial scale with several companies producing CNMs at tons-per-day scale. The recent developments in their production rate and their applications in various fields such as medical sector, environmental protection, energy harvesting/storage are comprehensively discussed in this review. We emphasize on the current trends and future remarks based on the production and applications of cellulose nanomaterials.Graphic abstract

Blue mould, caused primarily by Penicillium expansum, is a major threat to the global pome fruit industry, causing multimillion‐dollar losses annually. The blue mould fungus negatively affects fruit quality, thereby reducing fresh fruit consumption, and significantly contributes to food loss. P. expansum also produces an array of mycotoxins that are detrimental to human health. Management options are limited and the emergence of fungicide‐resistant Penicillium spp. makes disease management difficult, therefore new approaches and tools are needed to combat blue mould in storage. This species profile comprises a comprehensive literature review of this aggressive pathogen associated with pomes (apple, pear, quince), focusing on biology, mechanisms of disease, control, genomics, and the newest developments in disease management. Taxonomy Penicillium expansum Link 1809. Domain Eukaryota, Kingdom Fungi, Phylum Ascomycota, Subphylum Pezizomycotina, Class Eurotiomycetes, Subclass: Eurotiomycetidae, Order Eurotiales; Family Trichocomaceae, Genus Penicillium, Species expansum. Biology A wide host range necrotrophic postharvest pathogen that requires a wound (e.g., stem pull, punctures, bruises, shoulder cracks) or natural openings (e.g., lenticel, stem end, calyx sinus) to gain ingress and infect. Toxins Patulin, citrinin, chaetoglobosins, communesins, roquefortine C, expansolides A and B, ochratoxin A, penitrem A, rubratoxin B, and penicillic acid. Host range Primarily apples, European pear, Asian pear, medlar, and quince. Blue mould has also been reported on stone fruits (cherry, plum, peach), small fruits (grape, strawberry, kiwi), and hazel nut. Disease symptoms Blue mould initially appears as light tan to dark brown circular lesions with a defined margin between the decayed and healthy tissues. The decayed tissue is soft and watery, and blue‐green spore masses appear on the decayed area, starting at the infection site and radiating outward as the decayed area ages. Disease control Preharvest fungicides with postharvest activity and postharvest fungicides are primarily used to control decay. Orchard and packinghouse sanitation methods are also critical components of an integrated pest management strategy.

The food packaging industry has shown increasing attention toward biodegradable active packaging because of consumer demand for the extended shelf life of food products, as well as environmental concerns. In this study, the gelatin-based nanocomposite containing chitosan nanofiber (CHINF) and ZnO nanoparticles (ZnONPs) were fabricated and characterized by SEM analysis. The fabricated nanocomposite film revealed high antibacterial activity against foodborne pathogenic bacteria. To assess the efficiency of this bionanocomposite film for food packaging, chicken fillet and cheese was selected as food models. The results showed that the wrapping with nanocomposite film significantly ( p  < 0.05) decreased the growth of inoculation bacteria in chicken fillet and cheese samples. The changes in pH values and color parameters in chicken fillet and cheese samples were controlled by wrapping with nanocomposite film during storage time. At the end of 12-day storage, the weight loss of the wrapped chicken fillet and cheese samples with nanocomposite were 18.91 ± 1.96 and 36.11 ± 3.74%, respectively. In addition, the organoleptic characteristics of wrapped chicken fillet and cheese samples with nanocomposite film were acceptable until the end of storage. In conclusion, the fabricated nanocomposite can be suggested as a suitable packaging material for poultry meat and cheese to improve their shelf life and quality.

Listeria monocytogenes has emerged as a food safety concern for several produce commodities. Although L. monocytogenes contamination can occur throughout the supply chain, contamination from the packinghouse environment represents a particular challenge and has been linked to outbreaks and recalls. This study aimed to investigate the prevalence, persistence, and diversity of L. monocytogenes and other species of Listeria in produce packinghouses. A longitudinal study was performed in 11 packinghouses (whose commodities included microgreen, peach, apple, tomato, broccoli, cauliflower, and cucumber) in three U.S. states. In each packinghouse, 34 to 47 sites representing zones 2 to 4 were selected and swabbed. Packinghouses were visited four times over the packing season, and samples were tested for Listeria by following the U.S. Food and Drug Administration's Bacteriological Analytical Manual methods. Presumptive Listeria-positive isolates were confirmed by PCR. Species and allelic type (AT) were identified by sigB sequencing for up to eight isolates per sample. Among 1,588 samples tested, 50 (3.2%), 42 (2.7%), and 10 (0.6%) samples were positive for L. monocytogenes only, Listeria spp. (excluding L. monocytogenes) only, and both L. monocytogenes and Listeria spp., respectively. Five species of Listeria (L. monocytogenes, L. innocua, L. seeligeri, L. welshimeri, and L. marthii) were identified, and L. monocytogenes was the most prevalent species. The 102 Listeria-positive samples yielded 128 representative isolates (i.e., defined as isolates from a given sample with a different AT). Approximately 21% (21 of 102) of the Listeria-positive samples contained two or more ATs. A high AT diversity (0.95 Simpson's diversity index) was observed among Listeria isolates. There were three cases of L. monocytogenes or Listeria spp. repeated isolation (site testing positive at least twice) based on AT data. Data from this study also support the importance of drain and moisture management, because Listeria were most prevalent in samples collected from drain, cold storage, and wet nonfood contact surface sites.

Listeria monocytogenes is an increasing food safety concern throughout the produce supply chain as it has been linked to produce associated outbreaks and recalls. To our knowledge, this is the first systematic literature review to investigate Listeria species and L. monocytogenes prevalence, persistence, and diversity at each stage along the supply chain. This review identified 64 articles of 4863 candidate articles obtained from four Boolean search queries in six databases. Included studies examined naturally detected/isolated Listeria species and L. monocytogenes in fresh produce-related environments, and/or from past fresh produce associated outbreaks or from produce directly. Listeria species and L. monocytogenes were detected in each stage of the fresh produce supply chain. The greatest prevalence of Listeria species was observed in natural environments and outdoor production, with prevalence generally decreasing with each progression of the supply chain (e.g., packinghouse to distribution to retail). L. monocytogenes prevalence ranged from 61.1% to not detected (0.00%) across the entire supply chain for included studies. Listeria persistence and diversity were also investigated more in natural, production, and processing environments, compared to other supply chain environments (e.g., retail). Data gaps were identified for future produce safety research, for example, in the transportation and distribution center environment.

Listeria monocytogenes (LM) contamination of produce can often be traced back to the environment of packinghouses and fresh-cut facilities. Because there is limited information on the detection, prevalence, and distribution of this pathogen in produce operations, environmental \"routine sampling\" plans for LM and other Listeria spp. were developed and implemented in three packinghouses and five fresh-cut facilities in the United States. For routine sampling, a total of 2,014 sponge samples were collected over six to eight separate samplings per operation, performed over 1 year; vector and preproduction samples (n = 156) were also collected as needed to follow up on positive findings. In addition, a single \"validation sampling\" visit by an outside expert was used to evaluate the routine sampling. Among the 2,014 routine sponge samples collected, 35 and 30 were positive for LM and Listeria species other than LM (LS), respectively. LM prevalence varied from 0.8 to 5.8% for packinghouses and <0.4 to 1.6% for fresh-cut facilities. Among the 394 validation sponge samples, 23 and 13 were positive for LM and LS, respectively. Validation sampling found statistically significantly higher LM prevalence compared with routine sampling for three of eight operations. For all samples collected, up to eight isolates per sample were characterized by sequencing of sigB, which allowed for classification into sigB allelic types. Among the 97 samples with more than one Listeria isolate characterized, 28 had more than one sigB allelic type present, including 18 sponges that were positive for LM and another Listeria species and 13 sponges that were positive for more than one LM subtype. This indicates that collection of multiple isolates is necessary to capture Listeria diversity present in produce operations. Additionally, 17 of 77 sponges that were positive for LM were positive at only one enrichment time (i.e., 24 or 48 h), indicating that LM testing after two different enrichment times provides enhanced sensitivity.

The history of the meat packing industry of the Midwest offers an excellent illustration of the growth and development of the economy of that major industrial region. In the course of one generation, meat packing matured from a small-scale, part-time activity to a specialized manufacturing operation. Margaret Walsh's pioneering study traces the course of that development, shedding light on an unexamined aspect of America's economic history. As the Midwest emerged from the frontier period during the 1840s and 1850s, the growing urban demand for meat products led to the development of a seasonal industry conducted by general merchants during the winter months. In this early stage the activity was widely dispersed but centered mainly along rivers, which provided ready transportation to markets. The growth of the railroads in the 1850s, coupled with the westward expansion of population, created sharp changes in the shape and structure of the industry. The distinct advantages of good rail connections led to the concentration of the industry primarily in Chicago, but also in St. Louis and Milwaukee. The closing of the Mississippi River during the Civil War insured the final dominance of rail transport and spelled the relative decline of such formerly important packing points as Cincinnati and Louisville. By the 1870s large and efficient centralized stockyards were being developed in the major centers, and improved technology, particularly ice-packing, favored those who had the capital resources to invest in expansion and modernization. By 1880, the use of the refrigerated car made way for the chilled beef trade, and the foundations of the giant meat packing industry of today had been firmly established. Margaret Walsh has located an impressive array of primary materials to document the rise of this important early industry, the predecessor and in many ways the precursor of the great industrial complex that still dominates today's midwestern economy.

Food production-related facilities (farms, packing houses, etc.) are monitored for foodborne pathogens, and data from these facilities can provide a rich source of information about the population structure and genetic diversity of Salmonella and Listeria. This information is of both academic interest for understanding the evolutionary forces acting on these organisms and of practical interest to those responsible for controlling pathogens in facilities and to those analyzing data from facilities in the context of public health decision making. We have collected information about all positive isolates from facility inspections performed by the U.S. Food and Drug Administration for which whole genome sequencing data are available. The within- and between-facilities observed genetic diversity of isolates was computed and related to the common origin of isolates (as the common collected facility). This relationship provides quantification for assessing the relationship between isolates based on their genetic similarity quantified by single-nucleotide polymorphisms (SNPs). Our results show that if the genetic distance ( D) between two isolates is low, then more likely than not they are from the same facility or have some overlap in their supply chain. For example, if the genetic distance is no more than 20 SNPs, the probability ( P) that two isolates come from the same facility = 0.66 for Salmonella and 0.70 for Listeria. However, if two isolates come from different facilities, their genetic distance is likely large (for Salmonella, P( D > 20 SNPs) = 0.99982; for Listeria, P( D > 20 SNPs) = 0.99949); even if two isolates come from the same facility, their genetic distance is also very likely large (for Salmonella, P( D > 20 SNPs) = 0.794; for Listeria, P( D > 20 SNPs) = 0.692). These results provide insight into what SNP thresholds might be appropriate when determining whether two isolates are from the same facility and thus would be of interest to those investigating foodborne outbreaks and conducting traceback investigations.
