The California Department of Food and Agriculture said that a Southern California couple is facing criminal charges after allegedly being caught with 375 pounds of “bathtub” cheese at an open-air market in San Bernardino County, says.

The illegal soft cheese products are known to cause serious illness such as listeria, salmonella or E. coli.

The 375 pounds of seized illegal cheese included panela, queso fresco and queso oxaca varieties, the CDFA says. It was a significant find, the department says.

Infants, the elderly and those with weakened immune systems are the most susceptible. Expectant mothers should be especially guarded, as the listeria organism can cause miscarriages.
