The Chipotle at 9733 Sawmill Parkway in Powell was closed Monday following multiple complaints of food making customers sick. 
 
 The illness reports come from Iwaspoisoned.com, a website that consumers use to lodge complaints of what they believe to be foodborne illness. 
 
 The website, which is run by Patrick Quade, has six reports, alleging 12 people became sick this past weekend after eating at the store. Three of the complaints were filed Monday, two on Sunday and one is from Saturday. One of the complaints said a family of four ate there this weekend and three of them became ill. 
 
 Chipotle said they are investigating the reports and said that the store was closed Monday. Chipotle plans to reopen the location Tuesday.

 "We take all claims of food safety very seriously, and we are currently looking into a few reports of illness at our Powell, Ohio, restaurant," said Laurie Schalow, chief communications officer for Chipotle. 
 
 "We are not aware of any confirmed foodborne illness cases, and we are cooperating fully with the local health department. 
 
 Iwaspoisoned.com collects complaints from consumers on possible food poisoning cases and screens the reports for authenticity, Quade said. The site then uses the information to pinpoint what might be bigger problems with a particular location. Iwaspoisoned.com helped figure out the major outbreak at Chipotle locations in 2015. 
 
 The Chipotle store in Powell was last inspected by the Delaware General Health District on Thursday. The report cited two critical violations — one was for pinto and black beans that were not held at a high enough temperature, and one for cut lettuce that was not properly cooled after preparation. Both violations were corrected that day, according to the report. 
 
 On a positive note, the report from Thursday also said, "Observed great hand-washing while on site." 
 
 Chipotle has battled food safety concerns since 2015 when hundreds of people were sickened across the country, but mainly in Boston and California. In response Chipotle made changes to the way it handles its ingredients, but food-safety issues have lingered for the chain.

 More than 400 people said they fell ill after eating at an Ohio Chipotle that is thought to be at the center of an illness outbreak, according to a website that tracks foodborne illnesses. 
 
 A total of 228 reports have been made to the website iwaspoisoned.com suggesting that 418 customers have fallen sick after eating at a Powell, Ohio, Chipotle since Friday, according to Patrick Quade, the website's founder. The restaurant's address is 9733 Sawmill Pkwy. 
 
 The website saw a surge in reports after Business Insider's article late Monday revealing that Chipotle had shut down the restaurant over reports that customers had fallen ill. The site allows users to self-report suspected foodborne illnesses. Chipotle shares fell more than 3% in after-hours trading Monday. 
 
 The local health department, called the Delaware General Health District, is investigating the possible illness outbreak. The agency said Thursday that it has received 518 inquiries — including 95 emails and 423 calls — related to the possible illness outbreak, according to Traci Whittaker, a spokeswoman for the Delaware General Health District. 
 
 "The Health District food inspection team inspected the restaurant this afternoon," Whittaker said in an email to Business Insider on Tuesday. "Based on the food protection procedures followed by the facility, the inspection team found no reason for the facility to not reopen." 
 
 She said 33 stool sample kits were delivered Tuesday to people that reported illness. 
 
 Chipotle shut down the Powell restaurant on Monday over reports of customer and employee illnesses. 
 
 "We take all claims of food safety very seriously and we are currently looking into a few reports of illness at our Powell, Ohio, restaurant," Chipotle spokeswoman Laurie Schalow told Business Insider on Monday. "We are not aware of any confirmed foodborne illness cases, and we are cooperating with the local health department." 
 
 The Delaware General Health District said it received illness reports from seven customers on Sunday and Monday. In response, health officials arrived at the Chipotle restaurant on Monday for an inspection and found the restaurant closed. 
 
 Health officials then discussed the illness complaints with the company and discovered that Chipotle had also received four to five illness complaints from customers. Chipotle management said it was unable to get in touch with the health department to report the illnesses. 
 
 Chipotle also told health officials that two to five staff members called off work citing illness on Sunday and Monday. 
 
 Chipotle voluntarily closed the Ohio restaurant Monday for deep cleaning and removal of all exposed foods and single-use equipment, the company said. The company planned to reopen the restaurant on Tuesday. ||||| A Chipotle restaurant is at the center of a foodborne illness that sickened nearly 650 people. Hollis Johnson/Business Insider 
 
 Health officials say they have identified the cause of a foodborne-illness outbreak stemming from a Chipotle restaurant in Powell, Ohio, that sickened at least 647 people. 
 
 Stool samples taken from customers who got sick after eating at the restaurant tested positive for Clostridium perfringens, a foodborne illness that occurs when food is left at an unsafe temperature, according to Traci Whittaker, a spokeswoman for the Delaware General Health District. 
 
 In response to the outbreak, Chipotle CEO Brian Niccol said: "Chipotle field leadership will be retraining all restaurant employees nationwide beginning next week on food safety and wellness protocols." 
 
 He also said restaurants would be adding a "recurring employee knowledge assessment" to their daily food-safety routines. 
 
 "Chipotle has a zero-tolerance policy for any violations of our stringent food-safety standards, and we are committed to doing all we can to ensure it does not happen again," he said. Chipotle shares fell more than 4% Thursday afternoon. 
 
 The health department said that no specific food has been identified as the source of the illness and that the Centers for Disease Control and Prevention was conducting food and stool testing. 
 
 Business Insider reported last month that Chipotle temporarily closed the restaurant at the center of the outbreak, at 9733 Sawmill Parkway in Powell, on July 30 after receiving reports of customer illnesses. Reported symptoms included vomiting, diarrhea, and stomach pains. 
 
 Records show that local health officials inspected the Powell Chipotle on July 26 and found violations related to food not being held at proper temperatures. Specifically, they observed that lettuce was not properly cooled and that beans were not held at a warm enough temperature. 
 
 Customers who reported getting ill after eating at the restaurant visited the location between July 26 and July 30, according to the Delaware General Health District. No customers have reported getting sick after eating the restaurant since it reopened. 
 
 Health officials have inspected nearby Chipotle restaurants since the illness outbreak and found additional violations. 
 
 In two of the restaurants, inspectors found boxes of raw chicken "leaning" on other packaged foods, according to health records. Inspectors also found foods that were not being held at proper temperatures. 
 
 Chipotle has spent millions of dollars on measures to improve food safety after an E. coli outbreak three years ago affected restaurants in 14 states. ||||| A type of bacteria that forms when food is left out at unsafe temperatures caused Chipotle Mexican Grill's latest foodborne illness outbreak. 
 
 Nearly 700 people reported gastrointestinal problems, including nausea, diarrhea and fever, after eating at the Chipotle restaurant in Powell, Ohio, between July 26 and July 30. The Centers for Disease Control and Prevention's tests named clostridium perfringens the culprit of the outbreak. 
 
 The bacteria is one of the most common causes of food poisoning in the U.S. It forms when food is left out at unsafe temperatures. 
 
 The incident deals another blow to Chipotle, which has spent years trying to convince diners and investors it has improved its food safety practices. 
 
 An E. coli outbreak in 2015 sickened hundreds of people and plunged Chipotle into crisis. The fast-casual restaurant rolled out promotions and new menu items such as queso to try to win customers back. But diners continued to shun the restaurant. 
 
 Chipotle hired former Taco Bell CEO Brian Niccol in February to replace founder Steve Ells as CEO. Since taking the helm, Niccol has unveiled a strategy to woo consumers back to the troubled burrito chain with a focus on new menu items and faster mobile and online orders. 
 
 Its turnaround efforts appeared to be working. Shares of Chipotle have surged 74 percent this year. They slid 4 percent Thursday. 
 
 Niccol said Chipotle will start retraining all restaurant employees on food safety and wellness protocols next week. 
 
 The tests do not confirm the exact number of people who fell ill. Twenty samples were sent to the Ohio Department of Health and returned negative, a spokeswoman for the Delaware General Health District said. Six samples were sent to the CDC for more advanced testing and five returned positive for the toxin, she said. 
 
 The number of samples submitted are in-line with the Ohio Department of Health's guidelines.
– Food safety concerns are once again plaguing Chipotle: Consumer complaints filed on IWasPoisoned.com—a website that tracks possible food poisoning cases and helped reveal a 2015 E. coli outbreak at Chipotle locations—suggest close to 200 people have fallen ill after eating at a Ohio restaurant, per Business Insider. The location at 9733 Sawmill Parkway in the Columbus suburb of Powell closed Monday based on "a few reports of illness," with a rep noting "we are not aware of any confirmed foodborne illness cases," reports the Columbus Dispatch. The number of reports has since ballooned to 182 as of this writing, with most describing multiple people with nausea and diarrhea. In one case, a family of six, including four kids ages 1 to 8, describes coming down with food poisoning symptoms after "celebrating completion of the summer reading program with the coupons provided as prizes." Per the Dispatch, a Thursday health inspection at the location found pinto and black beans weren't kept at a high-enough temperature, while lettuce wasn't appropriately chilled. The inspection report noted both issues were corrected the same day, though Chipotle, whose shares fell more than 3% in after-hours trading Monday, says it's doing a deep cleaning of the restaurant anyway.
