CLEARWATER, Fla. – Doctors from BluePearl Veterinary Partners are urging people to stop using and return or discard certain Natura Pet Products food and treats after the company issued another recall due to potential Salmonella contamination Tuesday. 

This is the fourth such recall since March.

On Tuesday, Natura Pet Products issued a press release recalling specific lots of dry pet food citing the potential for the food to be contaminated with Salmonella, after routine testing performed by the Food and Drug Administration tested positive for Salmonella.

Natura is voluntarily recalling all products with expiration dates prior to June 10, 2014.

According to the release, the affected products are sold in bags through veterinary clinics, select pet specialty retailers, and online in the United States and Canada. No canned wet food is affected by this announcement.

People who have the potentially contaminated product should discard it immediately and stop handling it as it poses a risk to humans as well.

Common symptoms of salmonella in pets include nausea, vomiting, diarrhea, bloody diarrhea, lethargy, fever and abdominal discomfort.

A list of the recalled products are on the company's website: http://www.naturapet.com/recall
