On 17 June, German authorities announced that there was a major cluster at a slaughterhouse run by Tönnies in the city of Gütersloh. The states health secretary reported later that month, that a church service on 17 May 2020 attended by workers from the Tönnies factory and Westfleisch factory in Dissen is suspected to be the source of the cluster.[38] The smaller cluster in Dissen with initially some 90 infected people had been identified in mid May.[39] As a consequence of the new cluster with hundreds infected at slaughterhouse near Gütersloh, schools in the districts were closed until the start of the summer holidays on 29 June.[40] The company announced its entire workforce would be tested, with the production staff ordered to stay inside their living quarters when not at work until the remaining meat products had finished processing. Virologist Isabella Eckerle stated that she considered it "extremely unlikely" that the spate of infections had been the result of workers returning to their home countries in Eastern Europe over the preceding long weekend, and that a superspreading event was more likely to have been the cause of the outbreak.[41] On 23 June, the number of confirmed cases stood at above 1,500, Minister President Armin Laschet and State Health Minister Karl-Josef Laumann announced that neighbouring districts of Gütersloh and Warendorf would, until 30 June, be subject to the same contact restrictions as in March. Schools in Gütersloh would also close until the summer break. In the meantime, wide testing of the local population would be carried out in order to establish the extent of the outbreak; to that date, merely 24 cases outside the factory had tested positive. In response to the development, Bavaria issued a temporary ban for hotels to accommodate guests coming from any district which exceeded the threshold of 50 infections per 100,000 residents in the past seven days, unless travellers could produce an up-to-date negative coronavirus test.[42][43]

In October, the city of Cologne presented its #diesmalnicht (English: #notthistime) campaign discouraging gatherings, parades and similar hazardous behavior for the commencement of the Cologne Carnival at 11:11 a.m. on 11 November 2020. Mayor of Cologne Henriette Reker announced that there would be a ban on the sale and consumption of alcohol outside of restaurants and pubs on 11 November 2020, with many establishments voluntarily remaining closed or not selling alcohol on that date.[44][45]
