ABSTRACT In Canada, Salmonella-related foodborne illness accounts for more than 88,000 cases annually. Poultry products represent one of the major vectors for the zoonotic transmission of Salmonella. The majority of the current disinfection strategies that are applied in the poultry industry involve the use of diverse chemical antimicrobial agents; however, knowledge about the efficacy of novel antimicrobial technologies such as atmospheric cold plasma (ACP) and the potential of hurdle interventions is very limited. The objective of this study was to evaluate the synergetic effect of ACP and peracetic acid (PAA) as a hurdle antimicrobial intervention to reduce Salmonella enterica Typhimurium on raw poultry meat. Raw poultry meat samples were inoculated with Salmonella Typhimurium followed by the application of different treatments consisting of ACP and PAA (100 and 200 ppm) alone as well as in combination. Different hurdle interventions using PAA and ACP treatments resulted in significant (P ≤ 0.05) reductions in Salmonella Typhimurium, ranging from 2.3 to 5.3 log CFU/cm2, in comparison to PAA treatments alone with 100 or 200 ppm or ACP treatment alone, resulting in the reduction of Salmonella populations by 0.6, 1.3, and 2.3 CFU/cm2, respectively. Treatments involving application of PAA followed immediately by ACP and ACP followed by PAA resulted in the highest (P ≤ 0.05) reduction in Salmonella by 4.7 and 5.3 log CFU/cm2, respectively. Transmission electron microscopy images indicated that combined treatments resulted in destruction of Salmonella cells with visible cellular deformation and loss of cellular integrity. Color and moisture content of poultry meat samples were affected; thus, for large-scale application, further research needs to be done for optimizing this hurdle intervention. In conclusion, this study demonstrates the synergistic effect of ACP and PAA and its potential application for the safety of poultry products. HIGHLIGHTS

SummaryCertain synthetic organic compounds induce upon dissolution marked fibrinolytic activity in human plasma, reduce the antiplasmin titer of human or bovine serum and destroy the complement C1 of human plasma. Generation of fibrinolytic activity and reduction of antiplasmin are concentration-depending time reactions. Destruction of complement C1 occurs almost instantaneously. Minor molecular modifications abolish all three activities of the compounds.

The Stability

In this paper, I discuss the theory behind the use of a dense, concentrated neutron particle-based beam. I look at the particle based physics behind such a beam, when it is focused against solid material matter. Although this idea is still only theoretical, it appears that such a beam may be capable of disrupting the stability of the atoms within solid matter- in some cases by passing great volumes of neutrons between the electron and nucleus thus effectively “shielding” the electron from the charge of the nucleus. In other cases, by disrupting the nucleus by firing neutrons into it, disrupting the nucleus and weakening its bond on electrons. In either case- the resulting effect would be a disruption of the atom, which in the case of material matter would cause said material matter to fail, which would appear to the observer as liquification with some plasma generation. Thus, a dense neutron particle based beam could be used to effectively liquefy material matter. Such a beam could bore through rock, metal, or even thick, military grade armour, like that used on tanks- causing such materials to rapidly liquefy. The denser and thicker the neutron beam, the more devastating the effect of the beam- thus the faster material matter will liquefy and the greater the area of liquification. Such a beam would have applications in Defence, mining and drilling operations.
