It sort of depends on what the violations are. I think it would be different state agencies and possibly some Federal agencies depending on what is being done. For example, is environmental damage resulting from what they are doing? EPA? Are people’s health being jeopardized? Possibly CDC or Public Health? Do you have evidence (video, email, etc.) of the bribery? That in and of itself can be reported to law enforcement. Do not rule out the Health Department if they are the appropriate agency. Even if enforcement is difficult due to the small number of inspectors, a complaint would rise to the top of the investigation heap. Also, please be prepared for the consequences of whistle blowing. Corporations have phalanxes of attorneys to throw mud all over the whistle blowing. Every aspect of you personal life could be scrutinized. Depending on the dollar amount involved in terms of lost sales, possible fines or jail time for executives, you could even (although unlikelu) be in physical danger. Make sure you have as much documentary evidence as possible. Company documents supporting your assertions, etc. Whistle blowing is a noble thing, but can be hard on the whislte blower.
