Your good friend E. Coli just refuses to take a step out of the spotlight. A recent recall stemming from an E. coli scare now spans more than a dozen states and includes products sold at major grocery chains, including Walmart, Safeway, and Albertson’s. That’s right, there’s a chance that the fresh salad you’re currently eating right now is crawling with the waste of a barnyard animal. Dig in.

The whole situation spread from contaminated celery from California-based Taylor Farms Pacific. The company produces the celery in Costco’s chicken salad: a product recalled last week. The Food and Drug Administration (FDA) expanded the recall of food products on Tuesday, December 2nd. It now includes 155,000 items such as salad kits, vegetable trays and other prepared foods, as well as more than 45,000 Starbucks holiday turkey sandwiches that were distributed and declared as contaminated. The products affected by the bacteria were primarily distributed in Western states; but stores in states including Georgia, Arkansas, Nebraska, and Hawaii have also been affected.

This pesky bug typically originates from the guts of an animal that may end up on your plate. While the bacteria are harmless within the animal’s system, it can be potentially fatal to those who consume it. In this case, the bacteria were more likely than not spread by improper sanitation and hygiene within the food processing plant it originated from. With the appropriate care, E. Coli can be managed and dealt with relatively smoothly, but there are cases that tend to be more severe.

This isn’t the first outbreak of E. Coli in the States this year as Chipotle also suffered under the bacteria’s grip earlier this year. The Centers for Disease Control and Prevention said 19 people were infected in seven states across the U.S. from eating Costco’s chicken salad alone. Officials are continuing to investigate the outbreak.
