## 7 Regulations Currently in Effect  
According to the EPA's glyphosate Interim Registration Review Decision Case number 0178 of January 2020, glyphosate exposure poses no harm to human health. Although projected to be limited to the application area or nearby areas, the agency acknowledged potential ecological concerns for birds and mammals. In line with glyphosate's usage as an herbicide, the EPA identified a possible risk from off-site spray drift to terrestrial and aquatic vegetation. When glyphosate is used according to label directions, the EPA believes the benefits outweigh the potential environmental concerns [241]. However, because glyphosate is a component of several GBHs, there are concerns about the GBHs' regulation and management. [PERSON] et al. [242] reported that the EPA regularly reviews the maximum allowable quantities in retail GBHs, including the permission granted to farmers using them for a specific reason for feed and food purposes. The Food and Drug Administration is therefore in charge of ensuring that imported and domestic goods sold in stores do not violate the EPA's standards. The EPA issued glyphosate residue tolerances and determined the maximum allowable residue for all group 15 cereals at 30 mg/kg, except maize and rice, which are 5 mg/kg and 0.1 mg/kg, respectively; likewise, all oilseeds in group 20 to be 40 mg/kg, apart from canola, which is 20 mg/kg [243]. In Table 4, you can find a summary of the details of the glyphosate maximum residue limits (MRLs) set by different agencies for common cereals and grains  
Furthermore, in July 2017, the California Office of Environmental Health Hazard Assessment (OEHHA) listed glyphosate as a known carcinogen under Proposition 65 Law and Regulations [166]. This law ensures that California is informed about substances that could cause congenital disabilities, reproductive harm, or cancer. Meanwhile, the OEHHA claims that glyphosate exposure below 1100 ug/day has no significant risk level for cancer [244].  
Glyphosate residues in drinking water are regulated differently in different countries. In the United States, for example, glyphosate has a maximum contamination limit (MCL) of 700 ug/L [245] and 1000 ug/L in Australia [246].  
The use of GBHs was recently extended by the European Commission (EC) until 2022 when it will be reviewed. Based on EFSA [247], the EC established the MRL for sunflower seed, barley, sorghum, soybean, and oat at 20 mg/kg; 10 mg/kg for wheat, rye, mustard seed, linesed, lentils, peas, lupin, cotton seed and rapeseed; 1.0 mg/kg for corn; 2.0 mg/kg for beans, and 0.1 mg/kg for unnamed grains and cereals.  
Health Canada regulates herbicide and pesticide maximum residue limits (MRLs) [242]. It establishes a maximum allowable residue of 20 mg/kg for soybean and rapeseeds, 5 mg/kg for wheat, 15 mg/kg for oats, 10 mg/kg for barley, and maize at 3 mg/kg for glyphosate-treated crops.  
Globally, the World Trade Organization (WTO) plays a significant role in regulating GLY through its Agreement on the Application of Sanitary and Phytosanitary Measures, which all of the nations that make up the organization have in common. The Codex Alimentarius (18-3485), which outlines worldwide recognized accepted standards and recommendations, is updated by the WTO and FAO and reviews GBHs.
