ABSTRACT A 24-h direct plating method for fecal coliform enumeration with a resuscitation step (preincubation for 2 h at 37 ± 1°C and transfer to 44 ± 1°C for 22 h) using fecal coliform agar (FCA) was compared with the 24-h standardized violet red bile lactose agar (VRBL) method. FCA and VRBL have equivalent specificities and sensitivities, except for lactose-positive non-fecal coliforms such as Hafnia alvei, which could form typical colonies on FCA and VRBL. Recovery of cold-stressed Escherichia coli in mashed potatoes on FCA was about 1 log unit lower than that with VRBL. When the FCA method was compared with standard VRBL for enumeration of fecal coliforms, based on counting carried out on 170 different food samples, results were not significantly different (P > 0.05). Based on 203 typical identified colonies selected as found on VRBL and FCA, the latter medium appears to allow the enumeration of more true fecal coliforms and has higher performance in certain ways (specificity, sensitivity, and negative and positive predictive values) than VRBL. Most colonies clearly identified on both media were E. coli and H. alvei, a non-fecal coliform. Therefore, the replacement of fecal coliform enumeration by E. coli enumeration to estimate food sanitary quality should be recommended.

Определено содержание ингибиторов протеолитических ферментов в фасолевой муке, в пюре из зерновой фасоли, сваренной в воде, и в пюре из зерновой фасоли, сваренной после замачивания в воде в молочной сыворотке. Обосновано использование молочной сыворотки в качестве жидкой среды для варки зерновой фасоли после замачивания. Разработана технология полуфабриката в виде фасолевого пюре, предусматривающая замачивание фасоли в воде, варку в молочной сыворотке, грубое измельчение доведенной до готовности фасоли, последующее тонкое измельчение и охлаждение. Установлено, что в фасолевом пюре активность ингибиторов трипсина значительно ниже, чем в муке из фасоли, что делает пюре более предпочтительным полуфабрикатом для производства широкого ассортимента кулинарной продукции. The content of inhibitors of proteolytic enzymes in bean flour, in puree from beans harvested in water and in puree from cereal beans welded in milk whey after soaking in water is determined. The use of whey as a liquid medium for cooking grain beans after soaking is substantiated. The technology of semi-finished product in the form of bean puree, providing for soaking beans in water, cooking in milk whey, coarse grinding of the bean brought to the ready, subsequent fine grinding and cooling is developed. It has been found that the activity of trypsin inhibitors in bean puree is much lower than in bean flour, which makes mashed potatoes a more preferred semi-finished product for the production of a wide range of culinary products.

A mixed cocktail of four strains of Listeria monocytogenes was resuspended in product purge and added to a variety of ready-to-eat (RTE) meat products, including turkey, ham, and roast beef. All products were vacuum sealed in shrink-wrap packaging bags, massaged to ensure inoculum distribution, and processed by submersion heating in a precision-controlled steam-injected water bath. Products were run in pairs at various time-temperature combinations in either duplicate or triplicate replications. On various L. monocytogenes–inoculated RTE deli meats, we were able to achieve 2- to 4-log cycle reductions when processed at 195°F (90.6°C), 200°F (93.3°C), or 205°F (96.1°C) when heated from 2 to 10 min. High-level inoculation with L. monocytogenes (~107 CFU/ml) ensured that cells infiltrated the least processed surface areas, such as surface cuts, folds, grooves, and skin. D- and z-value determinations were made for the Listeria cocktail resuspended in product purge of each of the three meat categories. However, reduction of L. monocytogenes in product challenge studies showed much less reduction than was observed during the decimal reduction assays and was attributed to a combination of surface phenomena, including surface imperfections, that may shield bacteria from the heat and the migration of chilled purge to the product surface. The current data indicate that minimal heating regimens of 2 min at 195 to 205°F can readily provide 2-log reductions in most RTE deli meats we processed and suggest that this process may be an effective microbial intervention against L. monocytogenes on RTE deli-style meats.

Popish Plot

Through the stormy and divided history of religion in seventeenth and early eighteenth-century England runs one constant and unvarying stream—hatred and fear of popery. That ‘gross and cruel superstition’ haunted the protestant imagination. The murderous paranoia of the popish plot was the last occasion on which catholic blood was spilled in the service of the national obsession, but the need to preserve ‘our Country from Papal Tyranny; our Laws, our Estates, our Liberties from Papal Invasion; our Lives from Papal Persecution; and our Souls from Papal Superstition . . .’ continued to exercise men of every shade of churchmanship, and of none. Throughout the early eighteenth century zealous churchmen sought to keep alive ‘the Spirit of Aversion to Popery whereby the Protestant Religion hath been chiefly supported among us’, and publications poured from the press reminding men of the barbarities of the papists, ancient and modern, the fires of Smithfield and the headman’s axe of Thorn. Catholicism was bloody, tyrannical, enslaving, and cant phrases rolled pat from tongue and pen—popery and arbitrary government, popery and wooden shoes. The tradition was universal, as integral a part of the nation’s self-awareness as beer and roast-beef, and equally above reason. There were, observed Daniel Defoe, ‘ten thousand stout fellows that would spend the last drop of their blood against Popery that do not know whether it be a man or a horse’.
