Ninety‐five salmonellas and 40 non‐salmonellas were screened in the Bactometer using the standard formulation for Easter and Gibson's selenite cystine trimethylamine oxide dulcitol broth and versions in which dulcitol was replaced by mannitol or deoxyribose. More strains of salmonellas exceeded the current detection criteria (magnitude 250, rate 25) when dulcitol was replaced by either mannitol or deoxyribose as carbohydrate source. Using mannitol, more non‐salmonella strains exceeded the detection criteria than with either dulcitol or deoxyribose.
