Chipotle Mexican Grill announced earlier this week that it would stop purchases from a pork producer accused of violating animal welfare regulations and has since suspended the sale of pork-based products.
Following the announcement, the casual dining company's shares fell 0.6 percent to $709.74 on the New York Stock Exchange, Reuters reports.
"It shines their halo, but it has the potential to affect first-quarter" results, Miller Tabak & Co. analyst Stephen Anderson said, according to the site.
Anderson was making a reference to Chipotle's decision to publically pull pork-based "carnitas" from the menu, mentioning the announcement will gain the trust of customers concerned about organic produce and healthy products.
The company's management made the official decision to stop the purchase of pork from the supplier, which has not been publically named, on Friday. Chipotle officials claim the supplier's standards were not at an adequate level, since the casual dining restaurant requires that pigs be raised with outdoor access or open space.
The company has not announced pork suppliers it plans on working with in the future, but has disclosed that "carnitas" will likely return to store menus.
Approximately 6 to 7 percent of entrée orders are "carnitas," Chipotle officials also disclosed, according to Slate.
