It's believed that this suppressor is what hinders multiple eggs from responding to a single host. It is ... believed that the duration and intensity of release is based on the number of host organisms detected within a 10-meter range. If multiple organisms are present the intensity may be lessened, so that additional egg response is merely delayed slightly to minimize multiple attacks on a given host. Where as if an isolated host is detected the intensity would be enough to fully suppress any response from surrounding eggs, and possibly force those eggs into a state of inactivity or hibernation. The glands designated for the release of this pheromone are believed to be clustered at the base of the egg in the same area as the glands designated for larval agitation. This type of suppression is realatively commmon among eusocial societies - for example among honeybees the queen is known to release the pheromone "queen substance" which suppresses ovarian activity among the workers of a hive.
The common concern on raw eggs are bacteria infection such as Salmonella, ever since it has been found inside a small number of eggs. Scientists estimate that, on average across the U.S., only 1 of every 20,000 eggs might contain the bacteria. Therefore, the likelihood that an egg might contain Salmonella is extremely small - 0.005% (five one-thousandths of one percent). Statistically, the incidence of salmonella in non-organic eggs is one in 20,000. The chance of infection works out to once every 30 years based on the consumption of a dozen eggs a week.

In the US, increased public concern for animal welfare has pushed various egg producers to release eggs under a variety of different standards. The most widespread standard in use is used by United Egg Producers and is a volunteer welfare program known as United Egg Producers Certified(UEP Certified).[33] The program includes guidelines with regard to housing, feed, water, air, space allowance, beak trimming, molting, handling, and transportation; ... critics such as The Humane Society have alleged UEP Certification misleadingly allows for a significant amount of animal cruelty.[34] Other standards include "Cage Free", "Natural", "Certified Humane", and "Certified Organic." Of these standards, "Certified Humane", which carries requirements for stocking density and cage-free keeping, among others, and "Certified Organic", which requires hens have outdoor access and are fed only organic, vegetarian feed, among other requirements, are the most stringent.[35] [36]
eggstochick.gif (10381 bytes) Day 1: Ask students which animals they know come from eggs. After students have brainstormed animals that they know hatch from eggs, present a chart with three columns (yes, no, maybe) and pictures of a variety of animals. Let students take turns choosing an animal picture card and orally stating the animal's name. Let students decide if each animal definitely comes from an egg or definitely does not hatch form eggs. Let students share how they know this information. Place all other animal picture cards in the 'maybe' column on the chart.; Explain that all this week, we will read books to find out about which animals actually do hatch from eggs and which ones do not. Share that as we learn new information, the class will need to move some of the animals from the 'maybe' column to one of the other columns
