Given an average contamination rate of 9.7% with a probability of carrying either the A or the B allele of 0.7 (estimated from the current European population) the chances of this observation would increase (1253 p = 0.29; 1351c p = 0.25).
The contamination of the outdoor environment was at a similar level (6.8%) up to 2006, when for an unknown reason a slight increase in positive Salmonella findings was recorded, with an average contamination rate of 17.6% during 2007 2012.
During 1994 1998 the average contamination rate in the indoor environment of the "dirty zone" was close to 30% (29.1), but after substituting old equipment in 1998 the contamination dropped to a rather stable level at an average level of 7.8% throughout the remaining period (1999 2012) examined.
An audit of Ipswich's bins, conducted in mid-June, found that average contamination had dropped to 24.58%.
The findings showed an average PCB contamination of 7.5 parts per million, more than double the Federal limit of 3 parts per million for chickens, the nearest comparable bird.
Average bacterial contamination of hands before hand hygiene was 1.65 log.
In Poland, the average Hg contamination of fish and seafood is 0.035 and 0.022 mg/kg, respectively.
Based on kernel density estimation of mouse-expected coverage, the average mouse contamination of this particular xenograft was 21% of the total DNA content of the sample.
To monitor trends and detect producers with above-average contamination rates, incorporating the investigation of sprouted seed products in the routine program of food law enforcement in the Netherlands might be considered.
However, what has not yet been agreed on is whether it is more useful: (a) to determine the presence or absence of contaminated tubers in a seed lot, (b) the average tuber contamination level of a seed lot or (c) the distribution frequency of individual tuber with different contamination levels, as disease development is related to the latter (Tsror et al., 2012).
