It could be a brand-new restaurant, or there might be an issue with data collection. If you're not seeing a health inspection for a particular restaurant on Yelp, but nearby locations do have their data on Yelp, you may have found a location that we haven't covered yet. Please contact our support team to suggest new health department websites for us to cover. If this is the case, we'd like to hear from you. This situation could occur if the website has major issues that prevent us from collecting data accurately, or if the website is brand-new and we aren't aware that it exists. In a few rare instances, a health department may have their data online, but Hazel hasn't added the website to our automated data collection system. If both an inspection score and specific violation details are missing from a report, such data is considered too incomplete to show on Yelp. There are also a few health departments which do publish reports online but don't include sufficient details. You are also welcome to point them to our Public Health page, which provides information on different ways that Hazel can help enable and/or improve their online data publication practices.

To help us address your inquiry as quickly as possible, be sure to include the Yelp URL of the business, the name and street address of the business, and the URL of the health department's report (if available). If an inspection report has been published on a health department website more than two weeks ago and isn't appearing on Yelp, please contact our support team. If your health department doesn't post their reports quickly, we encourage you to speak with them or your local government officials to advocate for improving the way they publish data - the faster the reports are published, the sooner you and the rest of the general public can benefit from them. In practice, we find that the source of most delays is the lag time before the health department posts their report online you can refer to our whitepaper for an in-depth analysis. Additional quality control measures may, in some cases, result in further delays before the information is shown on Yelp.Once the report is published online, Hazel's data collection technology typically retrieves the information within 24-48 hours our data is sent to Yelp shortly afterwards.There may be a delay - lasting hours, days, or even weeks - before the report is published online by the health department, depending on how the agency operates.First, the health inspector has to complete their report and submit it to their health department.

When the health department, Hazel, and Yelp are all working quickly, the latest inspection for a business should appear on Yelp within a week. We aim to effectively use the underlying data to summarize the original inspection results, while not being overly harsh or lenient. Our system ensures that estimated scores in each health department jurisdiction follow a fixed distribution that's representative of average health department behavior. Only inspections that have no violations receive a perfect score of 100. To calculate an estimated score, our system considers the number of violations in an inspection, giving double weight to critical violations over non-critical violations, then assigns a score out of 100 points. Many health departments do not report inspection scores or grades, so Hazel collects underlying local health department data to provide an estimated score. These scores are labeled on the Yelp platform as being "estimated by Hazel Analytics."
