The Food Safety Modernization Act (FSMA) was signed into law by President Barack Obama on January 4, 2011. The FSMA has given the Food and Drug Administration (FDA) new authority to regulate the way foods are grown, harvested and processed. The law grants the FDA a number of new powers, including mandatory recall authority, which the agency had ...
In 1862, the government division called the Bureau of Chemistry was created. [15] The Bureau of Chemistry separated into two divisions in 1927, one of which was called the Food and Drug Administration (FDA). [16] As a new organization, the FDA had little legal control when enforcing the few regulatory food safety laws.
A 2011 study by Diana Zuckerman and Paul Brown of the National Research Center for Women and Families, and Steven Nissen of the Cleveland Clinic, published in the Archives of Internal Medicine, showed that most medical devices recalled in the last five years for "serious health problems or death" had been previously cleared by the FDA using the ...
A study suggests and defines a 'planetary boundary' for novel entities such as plastic- and chemical pollution and concluded that it has been crossed, suggesting – alongside many other studies and indicators – that more and improved regulations or related changes (e.g. enforcement- or trade-related changes) are necessary.
ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022).The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) [3] and the World Trade Organization (WTO) Principles for the Development of International Standards.

The rule arises because in a centrosymmetric point group, IR active modes, which must transform according to the same irreducible representation generated by one of the components of the dipole moment vector (x, y or z), must be of ungerade (u) symmetry, i.e. their character under inversion is -1, while Raman active modes, which transform ...
The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry.
Lipinski's rule of five, also known as Pfizer's rule of five or simply the rule of five (RO5), is a rule of thumb to evaluate druglikeness or determine if a chemical compound with a certain pharmacological or biological activity has chemical properties and physical properties that would likely make it an orally active drug in humans.
