In response to an outbreak of African Swine Fever in Croatia, starting from June 29, 2023, the Netherlands has implemented a requirement for all livestock transport vehicles returning or arriving from Croatia to undergo a second cleaning and disinfection upon entry. This regulation is governed by the Veterinary Measures for Specific Animal Diseases or Zoonoses Regulations. The Dutch Food and Consumer Product Safety Authority (NVWA) is responsible for monitoring compliance with these rules and has designated Croatia as an EU risk country.
