When the Office of the Texas State Chemist obtained 23 product samples from Texas Tripe, 16 tested positive for L. mono and Salmonella, indicating that over 70% of the samples collected were infected with harmful bacteria. Texas Tripe is made by cutting away most of the interior lining of the cow's stomach and then boiling it in acid to remove any residue of food or alcohol that might be present. The resulting product is white with a mild beef taste. It can be used as a meat substitute in dishes such as chili. The average person may be exposed to salmonella through contact with animals that are colonized with the organism. Persons who work with poultry and livestock are at greatest risk of being exposed to salmonella because they come into contact with contaminated surfaces or objects. Eating food that has been contaminated with salmonella may cause illness. Salmonella infection can be treated with antibiotics if treatment is needed. The duration of antibiotic treatment depends on how severe your case of salmonella infection is. People who recover from serious infections require additional treatment courses to prevent future episodes. Those who have only one episode of salmonella infection can be treated without following a routine after treatment.
