Your onions may do more than make you cry when you slice them, they may get you sick.

The Center for Disease Control is warning of a salmonella outbreak tied to onions. As of Thursday, there have been 652 cases causing 129 hospital visits across 37 states, including Colorado. However, the CDC says that number could be way higher and include some other states due to quick recovery times and determining if the ill are part of the outbreak.

Not all onions are bad, so determining which pungent veggies will harm goes as follows.

If it is a fresh whole red, white or yellow onions imported from Chihuahua, Mexico and distributed by ProSource, you'll need to throw it out. The CDC says these onions were sold to restaurants and grocery stores throughout the United States. The last import of the veggie was on Aug. 27, but they can last up to three months in storage and could still be in homes or businesses.

The CDC also said that investigators are still working to determine if other onions and suppliers are linked to the outbreak.

Officials say both individuals and businesses should check onions and if it is unknown where they are from, throw them away. It is also recommended to wash and sanitize any surfaces that may have come in contact with these onions.

The CDC says to call your healthcare provider immediately if you have any of these severe salmonella symptoms:

    • Diarrhea and a fever higher than 102°F
    • Diarrhea for more than three days that is not improving
    • Bloody diarrhea
    • So much vomiting that you cannot keep liquids down
    • Signs of dehydration, such as not peeing much
    • Dry mouth and throat
    • Feeling dizzy when standing up

According to the CDC, most people infected with salmonella experience diarrhea, fever, and stomach cramps. Symptoms usually start six hours to six days after swallowing the bacteria and most people recover without treatment after four to seven days.

So far, there has only been one reported case in Colorado. The worst of the outbreak has been in Texas and Oklahoma.
