If colonies matching The outline in Desk five are observed, carry on with even more identification by transferring the suspect colonies independently, via an inoculating loop, to the surface of Levine Eosin–Methylene Blue Agar Medium, plated on petri dishes. If several colonies are being transferred, divide the area of every plate into quadrants, Just about every of which may be seeded from a individual colony.

Time of sampling should be at the end of processing and packaging. The sample ought to be from homogenous bulk. Aseptic dealing with and approach are essential.
If colonies of Gram-detrimental rods matching The outline in Table 4 are uncovered, carry on with further more identification by transferring consultant suspect colonies individually, through an inoculating wire, to the butt-slant tube of Triple Sugar&#one hundred fifty;Iron&#one hundred fifty;Agar Medium by initial streaking the area from the slant and afterwards stabbing the wire well beneath the area. Incubate. If examination discloses no proof of tubes obtaining alkaline (red) slants and acid (yellow) butts (with or without the need of concomitant blackening on the butt from hydrogen sulfide production), the specimen fulfills the requirements on the test for the absence in the genus Salmonella.
For any fluid specimen in aerosol kind, chill the container within an alcohol-dry ice combination for about one hour, Lower open up the container, enable it to succeed in home temperature, permit the check here propellant to escape, or warm to generate from the propellant if feasible, and transfer the quantity of test content demanded for your procedures laid out in one of many two previous paragraphs, as acceptable.
