State health authorities announced on Tuesday that the tests made at a Peanut Corporation of America from Texas showed that the products made at the plant there might have been infected with salmonella. According to the Texas Department of State Health Services, the processing plant from Plainview was willingly closed on Monday night.

The laboratory tests made on the products prepared in Plainview showed that some of them might have been poisoned with the salmonella infection.

The Federal and Drug Administration announced on Tuesday that the peanut processing plant from Blakely, Georgia, has been closed after the thorough investigations had shown that the products prepared there have caused the deaths of eight people and sickened other 600 people from the entire nation.

While the FDA and the state investigators are proceeding with the tests in Texas, the processing plant from Plainview will be closed. The health authorities will check the procedures at the plant and its records of food safety. Yet, the state health agency added that no illness has been linked to the products made at Plainview Peanut Co. but the company will need to develop some precise criteria as to go on with its work.

Texas authorities also said that the peanut meal and the granulated peanuts haven’t been pulled out of the facility in Plainview. In addition, the dry roasted peanuts which have come out of the facility and reached a distributor have been pulled out of the market. Further investigations will show whether Plainview Peanut Co. was involved in the 43-state outbreak of salmonella.

The main peanut butter recall happened some weeks ago and included more than 1,000 products. The Peanut Corporation of America runs the processing plant in Texas too and wrote on its Web site that the facility in Plainview has voluntarily decided to close the production as to help the health authorities.
