Introduction
Intended Use
For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.
Principle and Interpretation
Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.
Formulation
Ingredients
/liter
Meat extract
4.3g
Enzymatic digest of casein
8.6g
Sodium chloride
2.6g
Calcium carbonate
38.7g
Sodium Thiosulfate (anhydrous)
30.4g
Ox bile
4.78g
pH8.0±0.2 at 25°C
Preparation
Suspend 89.4g in 1 L of purified water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks,and then cool to below 45°C. Add a vial of novobiocin sodium salt (SR0640), a vial of iodine solution and a vial of brilliant green (SR0040) into 100 mL of base medium. Mix thoroughly.
Quality Control
Cultural characteristics observed after incubation at 35-37°C for 24 hours
Quality control strains
Approx. Inoculum(CFU)
Expected Results
Salmonella typhimurium ATCC14028
10 – 100
≥ 10 cfu on XLD
Escherichia coli ATCC25922
> 104
≤100 cfu on TSA
Enterococcus faecalis ATCC29212
> 104
<10 cfu on TSA
Storage and Shelf Life
2-30℃,Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
Precautions
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Waste Disposal
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.
