Safe biological limits

Not following the scientific advice for extended periods bears considerable and increasing risk, whereas population modeling of the development of the population in the absence of fishing and assuming the low recruitment pattern of the past 10-15 years would still allow the population to increase above safe biological limits with 3-5 years (ICES, 2003, 2005). Recovery would occur even faster during the moratorium period if an inflow occurred that would increase reproductive success. 

Plants used to produce PRPs should be amenable to confinement . Isolation distances were increased, and the cultivation of food and feed crops following a PRP crop was discouraged. New hazard and exposure data for human and livestock health assessment may also be required from PRP-containing traditional food or feed crops prior to the approval of field trials. Exposure risk concerns the potential for PRPs to be present in human food or animal feed, and where exposure can occur, what mechanisms are used to limit biological activity. Hazards included direct toxicity and allergenicity in humans or animals as well as hazards presented by the coproduct streams that result from processing. These latter requirements could place a major burden on proponents to prove their materials are safe prior to even confined field trials. 

They must be safe. Illness is likely to result if consumers ingest too much of them, like contaminants (see Watson, 2001). Therefore numerical limits are set for many additives in EU law. Consumers can also become ill if some additives are not used. For example preservatives such as nitrite have to be biologically-active to work. The question is are they biologically-active against us A lot of scientific work had to be done before many preservatives were allowed for use in the European Community (now the EU). Preservatives were one of the first groups of additives to have their levels controlled in food so that consumers did not consume unsafe amounts of them. 

If an attack on a chemical asset or by a chemical or biological agent does occur, it is essential that the damage be contained, neutralized, and remediated as expeditiously and safely as possible. Most chemical production and storage facilities already have disaster recovery and containment plans in place in case of an accident. These plans are also generally applicable to intentional attack. By design, damage to production facilities and the potential for massive chemical release, especially outside the plant boundary, is expected to be limited. An industry-wide system is also in place for response to transportation accidents,...
