Ninja BN801

SaferProducts.gov consumer incident report 20241129-48CFB-2147334961. Severity: Injury, No First Aid or Medical Attention Received. Product: Ninja BN801 (Ninja Professional Plus Kitchen System, 1400 watts. This set contains a base unit, 2 smoothie cups, food processor container, and 72 oz pitcher.). Incident: I was using the Ninja Professional Plus Kitchen System to make smoothies. I smelled an unusual smell that smelled like something burning. I didn't see any smoke or any indication of a problem with the unit and thought the smell might be coming from outside my house. I served the smoothies to my 2 sons. One drank the smoothie; the other said it did not taste good. When I smelled his smoothie, it smelled like the same burning smell I smelled while making them. I put water and a few ice cubes in the Ninja smoothie container, put it in the base, and turned it on. I was shocked to see the water turn blackish with sediments of a black substance. I am very concerned because one of my sons drank the smoothie that had this substance. I kept the smoothie container that has the water and black substance, hoping it would be analyzed to determine what it is. The first week of November, when this occurred, I immediately contacted the Shark/Ninja company. The customer representative I spoke with told me they were going to expedite a return call to address my concerns and that I should hear back within two days. I did not hear back that week. The following week, I contacted the company again. Again, I was told they would expediate a response and that I should hear back within two days. It has now been four weeks, and I have not heard back from anyone at Shark/Ninja. My concern is that something from the machine entered the container and contaminated the contents of the smoothies I prepared. I am very concerned that this substance may have entered other food that I have prepared in the unit
