On this website, I do not always get to give good news, and this is one of these times.
Yes, this is legal. Fundraiser or not, a manufacturer does not have to provide their trade secrets any more than what is provided on the label of the product (which is mandated by federal law).
What happened is that the school club/organization contacted this company to run a fundraising campaign. The company obliged. The candy that they sent had the manufacturers package and label their food per federal guidelines and sent it to the school; they do not have to disclose anything else.
The school may have erred to get some questionable products or to use a questionable company. However, the manufacturer does not have to disclose anything else besides what is on the label. This would be no different than me calling X BRAND CEREAL and asking what their ingredients were. The manufacturer would tell me the same thing they told you - "we don't have to tell you."
Please note: If I tell you simply what you wish to hear, this would be unfair to you. I need to be honest with you and sometimes this means providing information that is not optimal. Negative ratings are reserved for experts who are rude or for erroneous information. Please rate me on the quality of my information; do not punish me for my honesty.
I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished. You may always ask follow ups at no charge after rating. Kindly rate my answer as one of TOP THREE FACES/STARS and then SUBMIT, as this is how experts get credit for our time. Rating my answer the bottom two faces/stars (or failing to submit the rating) does not give me credit and reflects poorly on me, even if my answer is correct. I work very hard to formulate an informative and honest answer for you; please reciprocate my good faith with a positive rating.
