Los Angeles ( CNN ) -- A group of county and city prosecutors in California have sued Walgreen Co. , alleging that the drug store chain broke state laws when disposing of hazardous waste , medical waste and customer records . Prosecutors asked a judge this week to issue a preliminary injunction against the company . The county and city attorneys originally filed a lawsuit in June , asked a judge to stop the company from improperly disposing of waste and consider fining the company for allegedly violating state laws . `` This was n't an isolated incident . Walgreen 's actions were systematic and statewide , and the company must be held accountable , '' Los Angeles City Attorney Carmen A. Trutanich said in a statement Monday . A company spokesman declined to comment on details of the case . `` We intend to work with state and local officials in order to resolve this matter , '' Walgreens spokesman Michael Polzin said in a written statement . The lawsuit , filed by 35 California district attorneys and two city attorneys , alleges that Walgreens stores improperly disposed of items like batteries , liquid corrosive waste , aerosol cans and pharmaceutical waste in company trash bins , sending them to local landfills rather than authorized disposal sites . The complaint also says Walgreens improperly disposed of customer records containing confidential medical information , failing to take required steps to protect privacy . The drug store chain should be fined , prosecutors say , under state health codes . `` Prosecutors contend that Walgreens systematically ignored those laws to cut costs , '' the Alameda County District Attorney 's Office said in a statement . Walgreen Co. mentioned the lawsuit in a filing with the U.S. Securities and Exchange Commission last month , citing regulations that require the company to disclose proceedings where monetary sanctions could exceed $ 100,000 . `` The company intends to work with state and local officials in an effort to resolve this matter , but can not predict the ultimate outcome of these efforts , '' the filing said . CNN 's Catherine E. Shoichet and CNN en EspaÃ±ol 's Jaqueline Hurtado contributed to this report .
