Also found in cantaloupes and unpasteurized apple juice. Because manure used for fertilization can be contaminated. Lives in conditions where there is no oxygen. Not all molds are dangerous, but some are. One of the most toxic substances that exist. We see this problem with carrot juice also. This happens on rare occasions, but it has indeed happened before. Norovirus: can sweet across ships and hundreds of people can be sickened by this particular microbe. Perceived risk: on real reaction but people think that there is.
