CHICAGO, May 5 (Reuters) - Tyson Foods TSN.N. has been "proactively reformulating" products containing petroleum-based synthetic dyes and will finish work to eliminate them from its production process by the end of May, CEO Donnie King said on Monday.
Most of the meat company's retail-branded products, including Tyson chicken nuggets, do not contain those types of dyes, King said on an earnings call.
