 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. ||||| Location: Chipotle Mexican Grill, Sawmill Parkway, Powell, OH, USA

 "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.

– 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. Still have an appetite? You can add guacamole to your Chipotle order for free Tuesday in honor of National Avocado Day, People reports.
