A new dengues outbreak linked to a woodgrain mill in the Dallas area raises questions for producers, processors and suppliers of woodgrain products.
The outbreak of denguing fever has sickened at least 713 people, according to the Texas Department of State Health Services.
A second outbreak has sickens at least 10.
The Texas Department for Agriculture, Forestry and Rural Affairs is investigating how the woodgrain industry is reacting to the outbreak.
The state has been working to increase woodgrain and grain processing safety standards.
The Wood Grain Association of America has said woodgrains have been in the news for years due to their popularity in the U.S. The association has been pushing the USDA for stricter regulations for woodgrills and other processing facilities.
Wood grain is considered the most common grain in the world, and there are more than 20 million acres of woodgrasses grown in the United States, according a USDA report.
