The U.S. Food and Drug Administration (FDA) has issued a recall of more than 50 products manufactured by homeopathic remedy company Terra-Medica after tests revealed that they  may contain penicillin or one of its derivatives as a result of the fermentation process used  during manufacture.

The Ferndale, Washington-based company, whose Website claims that its Pleo Sanum range of products  can “address acute and chronic inflammations and infections without the use of traditional  antibiotics,” has recalled 56 lots of Pleo-FORT, Pleo-QUENT, Pleo-NOT, Pleo-STOLO, Pleo-NOTA-QUENT,  and Pleo-EX homeopathic  products in all forms. Noting that “anyone who is allergic to penicillin, or allergic to  beta-lactam antibiotics, even at low levels, could have a serious or life-threatening anaphylactic  reaction if they consume the[] products,” FDA has urged consumers to report adverse effects to its MedWatch adverse event reporting program.
