NEW YORK (TheStreet) -- Chipotle Mexican Grill (CMG) - Get Report stock is decreasing 0.35% to $493.38 late Monday afternoon as the Mexican fast-casual chain reopened the restaurant that sickened students in Boston.

The company has responded with "aggressive actions to implement industry-leading food safety and food handling practices in all of its restaurants and throughout its supply chain," according to a statement.

More than 130 students were sick with the norovirus earlier this month after eating at one of the company's Boston restaurants, MarketWatch reports.

The restaurant reopened on Saturday after being closed for three weeks because of the highly contagious sickness which spreads because of contaminated food or surfaces, a Chipotle spokesperson told MarketWatch.

The norovirus outbreak came as two separate E. coli outbreaks affected Chipotle customers in 12 different states.

The company said it no longer has any of the contaminated ingredients that could be the cause of the outbreak and may never know what caused it.

Recently, TheStreet's Jim Cramer, Portfolio Manager of the Action Alerts PLUS Charitable Trust Portfolio commented on Chipotle, remainining optimistic: "The recent reports of outbreaks all came before the institutionalization of nationwide health standards that are the most strict of all restaurants. I would eat there any day of the week."

Separately, recently, TheStreet Ratings objectively rated this stock according to its "risk-adjusted" total return prospect over a 12-month investment horizon. Not based on the news in any given day, the rating may differ from Jim Cramer's view or that of this articles's author. TheStreet Ratings has this to say about the recommendation:

We rate CHIPOTLE MEXICAN GRILL INC as a Buy with a ratings score of B. This is driven by several positive factors, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, growth in earnings per share, increase in net income and notable return on equity. We feel its strengths outweigh the fact that the company has had lackluster performance in the stock itself.

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • The revenue growth came in higher than the industry average of 1.2%. Since the same quarter one year prior, revenues rose by 12.2%. Growth in the company's revenue appears to have helped boost the earnings per share.
  • CHIPOTLE MEXICAN GRILL INC has improved earnings per share by 10.6% in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two years. We feel that this trend should continue. During the past fiscal year, CHIPOTLE MEXICAN GRILL INC increased its bottom line by earning $14.13 versus $10.46 in the prior year. This year, the market expects an improvement in earnings ($15.52 versus $14.13).
