Molds are fungi that produce mycotoxins, some of which are capable of damaging the immune and nervous systems while others are known carcinogens. At the Food and Drug Administration (FDA) in Jamaica, NY the levels of mycotoxins are tested in dry foods as well as in chemotherapeutics in aquaculture. The four mycotoxins tested are deoxynavalenol and ochratoxin (found in wheat and maize), patulin (encountered in fruits and vegetables including apple juice and apple cide) and aflatoxin (found in nuts, figs and some spices). Mycotoxins are examined and analyzed using the spot testing method. The chemotherapeutic agents tested for are fluoroquinolone antibacterials that include ciprofloxacin, enrofloxacin, sarafloxacin, and difloxacin. The determination of these four fluoroquinolones is achieved using HPLC.
