| The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not... |

| Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies... |

| This study aimed to describe the characteristics of villages and women’s households that might induce environmental awareness among fuel wood collecting women in one location of Kenyan dry land. Two probit models were constructed to examine which parameters were associated with two dependent variables, afforestation action and thermal efficient improved cooking oven. Participation in age of respondent, family size and group-activities had a significant effect on two dependent variables. However, age and family size indicated opposite relation on two independent variables. Moreover, it could be considered that one of important factor of improved cooking oven was economically affordability because of large property (i.e. to have cows and lands). On the other... |

| In the Philippines, rootcrops play a significant role in providing livelihood and food security among the resource poor people living in fragile upland environment, which comprise about 65% of the total agricultural land in the country. This paper will present the factors which play into farmers’ decision-making strategies for varietal adoption, particularly of sweetpotato and cassava in Visayas Region, Philippines. Relative importance of factors as they are considered in the farmers’ decisionmaking process vary according to user-orientation (i.e. subsistent, semi-commercial and commercial) because such would have varietal trait specifications, scale of operations, and consequently, resource needs. In largely market or industry-oriented systems, the... |

| Thailand is a developing nation dependent on agriculture. Due to lack of modern public health practices, she suffers from the consequences of foodborne illnesses. The number of foodborne infection cases has nearly doubled in the past 10 years. Salmonella and Campylobacter pose the greatest risk of bacterial contaminants, mostly from pigs and chickens, and this paper will review livestock production systems and foodborne diseases from cases stemming from these sources. Due to the complexity of the livestock production systems, collection of data to date has been sporadic, but it is clear that controls are needed in slaughterhouse processing methods, and more communication between agencies and surrounding regions is paramount for proper surveillance to have... |

| 牛乳頭腫症は，牛パピローマウイルス（BPV: bovine papillomavirus）が牛の体表皮膚や一部の粘膜に感染することによって，感染部位に乳頭腫と呼ばれる良性腫瘍（イボ）を形成する疾患である．本病の発生は全国的に認められるが，わが国の牛の有病率についての大規模な調査は行われていない．本研究では，十勝地方のと畜場において雌雄，月齢および市町村毎の牛乳頭腫症有病率を調査し，疾病発生に関連するリスク要因について考察を行った．平成25年9月末より12月末までの3カ月間，週1回およそ80頭ずつ，合計1,085頭（雌657，雄428頭）の牛について乳頭部を観察し，腫瘍の有無を記録するとともにトレーサビリティーシステムを使って個体識別情報を収集した．陽性個体数は283頭（雌279頭，雄4頭）で，雌および雄の有病率はそれぞれ42.5%，0.9%であった．月齢が上がると有病率も上昇する傾向が観察できた．また，雌の陽性279頭と陰性378頭の月齢平均値を比較したところ，陽性牛の月齢（平均78カ月）が陰性牛のそれ（63カ月）より有意に高かった．有病率が高い市町村では，飼養されている牛の平均年齢も高い傾向がみられた．乳頭腫の発生は性別および年齢と有意に関連があり，雌であり，かつ月齢が高いほど，イボが観察される確率は高かった．一方，地域や季節，飼養管理方法，吸血昆虫の発生などの環境要因と有病率との関連性は明らかになっておらず，今後さらに詳細な調査が必要である．本調査によって，牛乳頭腫症発生の交絡因子として最も大きいのは雌雄の別であり，次に月齢であることがわかった．これらの情報は，牛乳頭腫症の防除対策を行う上で有用と考えられる． |
