Westmoreland Foodland Evacuation Story in the Herald-Dispatch

On August 31, the Herald-Dispatch ran a story detailing the events that happened at the Westmoreland Foodland on Monday. Their were coins that were covered in a white substance and after employees came into contact with the coins, they were saying that they felt ill. The story had a questionable use of the word "approximately," when it stated that, "Apporximately five or six Foodland employees were decontaminated at the scene and transported to the hospital to treat their symptoms."
Just saying five or six employees would definitely have been sufficient. When the number is that low and the range is one number, approximately is not needed. If the the number of employees was 10-20, then maybe approximately could be used. It is important to be accurate and concise in journalism also. I don't think it would have been that difficult to find the exact number of employees, rather than saying five or six. If you can't come up with exact information, your credibility as a journalist will be in jeopardy.
