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.
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.
| 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 |

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.
