We may be spicing our food with salmonella, according to a new report. About seven percent of spices tested by the US Food and Drug Administration were found to be contaminated with the deadly bug. Here's what you need to know.

According to a report in the New York Times last week, a study of more than 20,000 food shipments found that spices contained about twice the average salmonella contamination of all other imported foods. Plus certain spices had higher rates of contamination -- some 15 per cent of coriander and 12 per cent of oregano and basil shipments were contaminated. Other high levels were found in sesame seeds, curry powder, and cumin. Ground and cracked spices were slightly more likely to be contaminated than whole spices. The research was published in the June issue of the journal Food Microbiology.

National Public Radio (NPR) followed the report, citing that you wouldn't need to eat a lot of contaminated spices to get sick. Unfortunately, the microbe can go into hibernation while dry and reactivate in contact with water, perhaps in your stomach, NPR wrote.

But cooking can kill salmonella, as long as you use high heat. The US Centers for Disease Control and Prevention says you can kill salmonella at temperatures of 160 degrees F or 71 degrees C.

At this point, there is no requirement that spices be labeled as treated, at least in the US, meaning they've either being pasteurized or treated with ethylene oxide, NPR writes. Even though spice exporters such as India have been trying to improve practices, NPR adds that it might not be enough. "You're not going to change what happens in a farm in India or in the Spice Islands," Theodore LaBuza, a professor of food safety at the University of Minnesota, told the website. "They just don't have the technology for that." After becoming aware of the salmonella risk, he stopped putting rosemary on his salads and opts to use spices in cooking instead.

    If hot spices like cayenne and chili powder make your eyes water, that’s probably a sign other animals might have a similar reaction.

  • Make Spiced Candles

    For those interested in using spices in homemade crafts, candles are another great way to put your old spices to work. Find a basic candle-making recipe or use one that mentions spices like <a href="http://www.ehow.com/how_5476198_add-fresh-spices-scent-candles.html" target="_blank">this one</a> from eHow.com. Select a nice-smelling spice and add a tablespoon to your candle mixture. For this project, be sure to use ground spices, since whole spices can cause a <a href="http://www.ehow.com/how_5476198_add-fresh-spices-scent-candles.html" target="_blank">fire hazard</a>.

  • Grill

    Over time, spices begin to <a href="http://www.thespicehouse.com/info/faq" target="_blank">lose their volatile oils</a>, which makes them less beneficial in cooking. It is possible to get a little more use out of them for food if you know what to do, though. <a href="http://www.thespicehouse.com/info/faq" target="_blank">The Spice House</a> recommends tossing your old spices on your grill. This method of cooking may help release any remaining volatile oils and flavor your food.

  • Deodorize

    Perhaps not surprisingly, spices can neutralize odors, making them a good candidate for freshening up your house. Placing spice-filled sachets in drawers can help eliminate stale odors, according to <a href="http://www.thedailygreen.com/green-homes/latest/spice-uses#slide-5" target="_blank">The Daily Green</a>. Reader’s Digest even suggests using spices to remove unpleasant smells from bottles and thermoses. Follow their <a href="http://www.rd.com/home/12-problemsolving-spices/" target="_blank">instructions</a> to clean your drink containers using dried mustard and cloves. You can also boil spices like whole cloves or cinnamon sticks to freshen your whole kitchen.

  • Grow Them

    If you have whole spices like anise stars, coriander seeds, cumin seeds, dill or plenty of others, you can <a href="http://permaculturenews.org/2012/03/15/seeds-from-the-kitchen-cupboard/" target="_blank">try planting them</a> to see if they grow. Since these types of spices were seeds all along, they may germinate, though success may depend on how old those seeds are. (If you’ve had those caraway or mustard seeds in the back of the pantry for the last decade, you may be out of luck.) With any spice, it’s important to store it properly to maintain freshness as long as possible. Storing spices in airtight, glass containers is ideal, and keeping them in the refrigerator can make them last longer as well. Whatever you do, don’t store them above the stove, explains <a href="http://www.thespicehouse.com/info/faq" target="_blank">The Spice House</a>, because the heat will destroy the spices’ oils.
