Up until that time, I don't have any specific information about people stopping the use of Cascade dishwasher detergent due to lingering taste and smell issues.
However, it is not uncommon for companies to reformulate their products or make changes to their formulas based on customer feedback and changing regulations. If you are experiencing a stronger taste and smell with Cascade dishwasher detergent, it is possible that there has been a reformulation or a change in the manufacturing process.
If you are concerned about the product's performance or have experienced adverse effects, I recommend reaching out directly to the manufacturer's customer service or checking for recent customer reviews to see if others have reported similar issues. Additionally, you may consider trying alternative dishwasher detergents to see if the problem persists or improves.
