A recall of E.coli-tainted lettuce expanded late Monday as another food company said it was recalling lettuce grown on an Arizona farm currently under investigation by the U.S. Food and Drug Administration as a potential source of the outbreak.

According to the Associated Press, California-based Andrew Smith Co., said it is recalling lettuce sold to Vaughan Foods of Moore, Okla., as well as a distributor in Massachusetts. Andrew Smith spokeswoman Amy Philpott told the AP that she would not identify the Massachusetts distributor because the lettuce in question is already past its expiration date.

In the meantime, the FDA is investigating the Yuma, Ariz.-based farm as a potential source of contaminated lettuce that has so far sickened 19 people nationwide. Possible E. coli contamination has already prompted the recall of Freshway Foods' romaine lettuce, which is sold in 23 states and the District of Columbia, the FDA said last week.
