Determine occurrence of mold in percentages. Hafner, New York. In living cells, the cell wall stains brighter and is more defined than the plasma, which is less prominent and uniformly stained. These substances can be found in a variety of very important agricultural and food products, primarily dependent of product moisture content, and its water activity, relative air humidity, temperature, pH value, composition of the food matrix, the degree of its physical damage, and the presence of mold spores. This is set out in: Provisions for sampling and analysis are applicable for enforcement bodies only, this includes local authorities, port health authorities and public analysts. Six classes of mycotoxins most frequently affect common pet food ingredients like wheat, rice, oats, barley, and corn: aflatoxin, DON (vomitoxin or deoxynivalenol), fumonisin, ochratoxin, type A tricothecenes (T-2 and HT-2) and zealarone.
