Prepare to feel your skin crawl: Food Safety and Inspection Service have closed the Foster Farms chicken plant in Livingston, CA upon discovering unsanitary conditions due to a cockroach infestation. The closure comes almost a year too late in the eyes of some, after hundreds of people fell ill in a Salmonella outbreak.

In light of a letter from federal inspectors, the plant closed Wednesday to undergo “enhanced sanitizing” (read: kill all of the disgusting roaches that might contaminate the chicken). The news is somewhat shocking, considering that less than a month ago, Dan Englejohn, assistant administrator of the USDA’s Office of Field Operations, told USA TODAY that Foster Farms had proven to the agency that the company was taking steps to control contamination at the plants.

Apparently not.

An excerpt from the letter, obtained by The Oregonian, read “These recent findings of egregious insanitary conditions related to a cockroach infestation in your facility indicate that your establishment is not being operated and maintained in sanitary conditions.” Cockroaches are known carriers of some of the heaviest hitters in the disease world, including Salmonella and other bacteria.

The plant is associated with a Salmonella outbreak that began in February of 2013, with a 416 people in 23 states reporting sickness as a result of consuming chicken from the facility. Given the prolonged sanitation issues, some health experts wonder why the plant wasn’t shutdown sooner.

According to USA TODAY, Seattle food-safety lawyer Bill Marler found it strange that the USDA “has the power to shut a plant down when they found cockroaches but doesn’t have the power to shut them down when they poison hundreds of people with antibiotic-resistant salmonella.”

The FSIS document cited Foster Farms for live cockroaches at the Livingston facility on September 14, 2013, November 4, 2013, December 28, 2013, and January 7, 2013. Cockroaches were “observed and documented on multiple days (including on two consecutive days) in multiple locations within the establishment.”

“No products are affected. Product production has been transferred to the company’s other facilities,” the company said in a statement.

Thus ends your daily reminder to always handle chicken properly, and cook it to an internal temperature of at least 165 degrees Fahrenheit.
