PREVIOUSLY: The Associated Press reports:

SCARBOROUGH, Maine -- Hannaford Supermarkets is alerting consumers that Cargill Beef is voluntarily recalling 29,339 pounds of ground beef that may contain salmonella.

The 85-percent-lean ground beef was produced at Cargill's plant in Wyalusing, Pa., on May 25, and repackaged for sale to consumers by customers of the Maine-based grocery chain.

Cargill President John Keating says in a statement, "Food borne illnesses are unfortunate and we are sorry for anyone who became sick from eating ground beef we may have produced."

Hannaford's says consumers should check their ground beef for "use or sell by" dates between May 29 and June 16. Refunds will be offered for ground beef that is returned.

According to the USDA, 33 people have been sickened in seven states (MA, ME, NH, NY, RI, VA, VT). The onset of illnesses began in early June but it took several weeks to link the salmonella cases across five case-patients. Two of these cases involved hospitalization. This particular strain -- Salmonella Enteritidis -- can be treated with antibiotics.

For more details on the beef being recalled, the USDA has details here and Cargill has a ground beef recall site with information. The use-by date of the beef affected has expired, and the meat is no longer available for retail sale.

  • Campylobacter Enteritis

    A common bacterial infection producing severe gastrointestinal upset that can hang around as long as two weeks. It's rarely fatal in healthy people. <strong>The culprits: </strong>Improperly slaughtered or processed meat not thoroughly cooked, contaminated vegetables, milk or water. Pets can also shed the bacteria through their "business." <strong>What it feels like: </strong>You'd pay closer attention to the flulike symptoms (fever, aches and pains) if you weren't running to the bathroom every 15 minutes of your life. <strong>Maybe you shouldn't have: </strong>Plucked that mass-processed pack of pork chops out of the "manager's special" bin. Also, if you really need to be told, leave seagulls alone. They're neither friendly nor tasty and are known to harbor higher concentrations of the bacteria. Common sense and decent kitchen cleanliness should protect you from needless downfall. <strong>Related: <a href="http://www.foodrepublic.com/2011/08/31/are-these-5-foods-trying-kill-you?utm_source=huffingtonpost.com&utm_medium=partner&utm_campaign=food-poisoning" target="_hplink">Are These 5 Foods Trying To Kill You?</a></strong> <em>Photo via Flickr user <a href="http://www.flickr.com/photos/stuartwebster/5829527553/" target="_hplink">StuartWebster</a></em>

  • Cholera

    Contrary to what literature might have you believe, there will be no love in the time of cholera, only misery, woe and lots of diarrhea. <strong>The culprits:</strong> Contaminated water and eating raw or undercooked seafood that was hanging out in that water. <strong>What it feels like:</strong> Being slowly dried in a dehydrator that looks surprisingly like your bathroom while your abdomen is squeezed by a giant godlike fist. You might just want to set up shop in there for a spell, the toxin in the cholera bacteria causes any water in your body to "release." Replenish as you might, it likely won't stay in there very long. Keep at it diligently, though, and you'll be fine in about a week. <strong>Maybe you shouldn't have:</strong> Splashed around in a stagnant portion of the Meekong Delta for so long, or eaten those Mexican oysters with quite as much gusto. <em>Photo via Flickr user <a href="http://www.flickr.com/photos/philosophygeek/3964899327/" target="_hplink">philosophygeek</a></em>

  • E. Coli Enteritis

    The black sheep of the food poisoning world, E. coli's the one with a strain that'll actually kill you regardless of treatment attempts. How subversive. <strong>The culprits</strong>: Escherichia coli, or E. for short, has one incredibly powerful strain: O157:H7, although other related strains can cause infection as well. This bacterium is found in mass-processed ground beef and on vegetables that were improperly cleaned or handled by contaminated fingers. <strong>What it feels like:</strong> You've been stabbed in the colon, which would explain the crippling cramps and other things that might happen if one were actually stabbed in the colon, including blood. Not that there's a "better" food poisoning to get, but this is one you really want to avoid. <strong>Maybe you shouldn't have:</strong> Eaten that rare burger of questionable origin while chugging raw milk in that crazy crowded public pool, all of which have been known to harbor the bacteria. <strong>Related: <a href="http://www.foodrepublic.com/2011/06/06/update-new-e-coli-culprit-europe?utm_source=huffingtonpost.com&utm_medium=partner&utm_campaign=food-poisoning" target="_hplink">Update: New E.

  • Ciguatera (Fish Poisoning)

    An incurable disease caused by eating fish contaminated by coral algae toxins. A real doozy, with an estimated 50,000 cases each year. <strong>The culprits:</strong> Ciguatera is limited to fish of tropical origin. It's impossible to detect by seafood processors, and can't be killed by cooking or freezing. Live in fear of grouper, or continue on with your life with relatively minimal risk. <strong>What it feels like:</strong> At first, typical food poisoning symptoms may present, but the bigger problem with ciguatera is its severe and often irreversible neurological effects. These can include trouble sensing hot or cold, tingling "phantom limb" pain in the extremities and other symptoms that may be confused with anything from multiple sclerosis to heart failure. <strong>Maybe you shouldn't have: </strong>Hit that fried "mystery tropical fish" eating contest at that Margaritaville in that tropical location with your buddies. To minimize your risk of catching this seriously unfun bug, make sure you know what your fish is and if possible, where it came from. Larger fish from shallower waters in a tropical environment are your worst bet. <strong>Related: <a href="http://www.foodrepublic.com/2012/04/06/trouble-brewing-fda-and-sushi?utm_source=huffingtonpost.com&utm_medium=partner&utm_campaign=food-poisoning" target="_hplink">Trouble Brewing For The FDA.

  • Listeria

    The range of listeria infection, or listeriosis, lands you somewhere between asymptomatic and dead and can occur from eating or drinking basically anything that was grown, raised or milked. <strong>The culprits:</strong> Raw or improperly pasteurized dairy products, vegetables grown in contaminated soil (yup, it can live in soil), preserved and smoked meats (can be identified by a slippery or slimy film), canned and raw seafood and fresh fruit. <strong>What it feels like:</strong> A bad flu, although more serious complications like meningitis can occur in people with weakened immune systems, as well as in young children, pregnant women and the elderly. <strong>Maybe you shouldn't have:</strong> Eaten all those root vegetables straight from the ground without washing them right after milking your cow. I mean a hippie farmer's life is great, unless your land is rife with listeria. <em>Photo via Flickr user <a href="http://www.flickr.com/photos/9229859@N02/2575380447/" target="_hplink">bucklava</a></em>

  • Staphylococcus

    This is the picnic food poisoning everyone warns you about, especially you, dude who brought the mayo-choked potato salad (<a href="http://www.foodrepublic.com/2012/02/10/potato-salad-horseradish-recipe ?utm_source=huffingtonpost.com&utm_medium=partner&utm_campaign=food-poisoning" target="_hplink">try this one instead</a>). <strong>The culprits:</strong> The bacteria releases its toxins at the comfy incubator that is room temperature food, which gives staph food poisoning its signature cookout-ruining reputation. The worst part? Reheating contaminated food won't kill it off. Actually the worst part is the symptoms. <strong>What it feels like:</strong> Explosive, and not in a romantic feelings kind of way. Within an hour of ingesting contaminated food, both ends will be entirely occupied for up to a day. The good news is, once it's out, it's out and you can get right back to the picnic. Oh wait, it's over. <strong>Maybe you shouldn't have:</strong> Microwaved that leftover potato salad thinking no bug could possibly survive the ordeal. <em>Photo via Flickr user <a href="http://www.flickr.com/photos/stuart_spivack/274140418/" target="_hplink">stu_spivack</a></em>

  • Salmonella

    The bacteria that causes salmonellosis, or salmonella poisoning, has a serious reputation among poultry and their handlers, and BOY does it love hanging out on the stretches of counter you missed with the sanitizer. <strong>The culprits:</strong> Although eggs, processed chicken parts and other raw meat are particularly good at spreading the bacteria, pet reptiles and rodents are also carriers. Wash everything any dead or live animal comes in contact with and maybe don't allow live animals in the kitchen while you're cooking, period. <strong>What it feels like:</strong> Your small intestine betraying you entirely. Expect a week or so of your typical diarrhea, abdominal cramps and possibly a fever. <strong>Maybe you shouldn't have:</strong> Attempted your own Japanese-style chicken breast sashimi or let Shelly the turtle roam around willy-nilly on the cutting board. Especially before slicing said chicken sashimi. <em>Photo via Flickr user <a href="http://www.flickr.com/photos/vseehua/518875309/" target="_hplink">Casper Jen</a></em>

  • Shigellosis

    Similar to salmonella but yet so very different is shigella, which attacks the large intestine rather than the small. <strong>The culprit: </strong>You're going to love this -- human waste. While plenty of food-borne illness can be spread this way, particularly by catching a ride in food or water, many cases of shigellosis can be directly attributed to contact with... well, you know. It can also be resistant to antibiotics, so definitely practice safe sewage-wading. <strong>What it feels like: </strong>Salmonella, only with more blood. <strong>Maybe you shouldn't have:</strong> Taken on that blackout drunken dare to see what's really under that manhole by the creek, then gone straight to In-N Out. Just maybe. We live in a developed nation, you almost have to try to get this one. It's Darwinism, people. <em>Photo via Flickr user <a href="http://www.flickr.com/photos/nathanreading/6141237661/" target="_hplink">Nathan Reading</a></em>
