Tetrathionate (TT) Broth Base, Hajna is used as a selective enrichment for the cultivation of Salmonella species (except S. typhi) from samples in a laboratory setting. Tetrathionate (TT) Broth Base, Hajna is not intended for use in the diagnosis of disease or other conditions in humans.

Tetrathionate Broth Base, Hajna, is recommended in the Compendium of Methods for the Microbiological Examination of Foods and the FDA/BAM for the Environmental Sampling and Detection of Salmonella Enteritidis (SE) in Poultry Houses and whole eggs. Salmonella organisms may be present but injured in food-processing procedures, which include exposure to low temperatures, sub-marginal heat, drying, radiation, preservative, and sanitisers. Numerous reported cases of Salmonella enteritidis (SE) infections are associated with contaminated shell eggs. SE infections can be very serious and symptoms can include diarrhea, fever, abdominal cramps, headache, nausea and vomiting. Eggs can become contaminated on the farm because a laying hen can become infected with SE and pass the bacteria into the egg before it is laid. If the egg is not refrigerated, the bacteria can grow inside the uncracked, whole egg. Tetrathionate Broth Base, Hajna was developed by Hajna and Damon.
