At least 78 people have now been sickened in a Salmonella outbreak affecting residents of northwestern Texas, according to various news reports.

A large portion of the patients are connected to the Ten in Texas steakhouse in Dalhart, TX, while more cases have sprung up in the communities of Bushland and Amarillo.

Health authorities have not been able to track down the exact source of the outbreak.

Ten in Texas voluntarily shut down for a short time last month for a thorough cleaning and sanitization process.
