According to paragraph (b)(1) of section 150.140 of title 21 of the Code of Federal Regulations, a food may only labeled as "jelly" if it has a blend of two , three, four or five fruit juice ingredients
Anyone is free to sell a jelly that combines Dewberry, Gooseberry, Loganberry and Youngberry. Under 21 C.F.R § 150.140(b)(2), the Food and Drug Administration definitely allows that mixture. Also a jelly with the same recipe with additional Boysenberry or Prickly Pear can also be sold. But if Boysenberry and Prickly Pear alone for a jelly is not allowed, the six fruit juices should be added on it in order to label that product as "jelly". Those who don't follow the guidelines, is a criminal.
Under paragraph g of section 343 of Title 21 of the U.S. Code, it is indicated that to sell a food product labeled as "jelly" is a federal crime unless that product will meet the certain definitions and standards.
Smucker's, a large corporation that sell jelly, is very much able in knowing these standards. But mom-and-pop sellers may perhaps incorrectly run afoul of jelly policy or countless further food regulations.
Treason, piracy and counterfeiting are few crimes included in the original federal criminal code. Every person should impulsively be familiar and comprehend these crimes. It is obvious that the corporate legal department is not needed just to know that murder, arson and theft are immoral and illegal.
In the present day we have almost 5.000 federal criminal laws and additional 300,000 or more federal criminal regulations. No sensible individual could identify the entire manner that federal law criminalizes. What everybody does recognize is there are lots of crimes to tally.
That is the reason why Heritage Scholars have emphasized the over criminalization problem and disagreed for a narrow mistake of law defense and a default mens rea standard to oppose the absolute quantity and often unpredictable nature of federal regulatory crimes that lock in unaware offenders.
