Tuolumne County public health officials urge residents to check their shelves and freezers for raw beef products from JBS Tolleson Inc. that could be contaminated with salmonella.

The company based in Tolleson, Arizona, recalled more than 6.5 million pounds of beef products last week after a federal investigation linked them to a multistate salmonella outbreak that has sickened more than 50 people, including four in California.

Potentially contaminated JBS raw beef products are said to have expiration dates from July 26 to Sept. 27.

Save Mart grocery stores throughout California may have received the potentially contaminated products, in addition to FoodMaxx and Lucky stores. The county Environmental Health Department has advised local stores to discard any JBS raw products with the expiration dates in question.

The Tuolumne County Public Health Department is not aware of anyone locally getting sick from eating the contaminated products, according to Michelle Jachetta, health program supervisor and emergency preparedness coordinator.

“It should be kind of winding down, but we just want to make sure people are aware and check the stuff they have in their freezer,” she said.

A press release stated that the outbreak is tied to a specific strain called Salmonella Newport, which is believed to be linked to the use of antimicrobial agents in agriculture.

Symptoms of an infection typically begin within 12 to 36 hours of consuming tainted food, but have been documented to take as long as 16 days to appear depending on how much was ingested.

The symptoms of Salmonella Newport infection are commonly the sudden onset of diarrhea, abdominal pain, fever, nausea and vomiting, which usually last for several days. Deaths are typically uncommon, except in the very young, elderly, debilitated or people with compromised immune systems.

No deaths have been reported in the 57 cases reported since last week.
