Description
本発明は、特に靴底に付着したサルモネラの殺菌消毒に有効な靴底消毒マット用殺菌消毒液組成物及び靴底に付着したサルモネラの殺菌消毒方法に関する。 The present invention relates to a sterilizing liquid composition for a shoe sole disinfecting mat that is particularly effective for sterilizing salmonella adhered to a shoe sole, and a method for sterilizing and disinfecting salmonella adhered to a shoe sole.
ビグアナイド系殺菌剤や第４級アンモニウム塩系殺菌剤は、手指、患部、医療機器、台所周りや浴室、繊維材料などの殺菌消毒のための種々の殺菌消毒剤の主成分として使用されており、用途に応じた種々の改良が行われている。例えば、特許文献１には、優れた殺菌消毒力を保持したまま、使用時の皮膚刺激を減少し、使用後の触感を著しく改良した第四級アンモニウム塩系殺菌消毒剤又はビグアナイド系殺菌消毒剤を含有する殺菌消毒剤組成物が開示されている。この殺菌消毒剤組成物は、第四級アンモニウム塩系殺菌消毒剤又はビグアナイド系殺菌消毒剤の低級アルコール溶液に対して、凝固点が３５℃以上のポリアルキレングリコール又は凝固点が３５℃以上のアルキレングリコールの誘導体を０.０１〜２重量％配合してなるものである。
又、特許文献２には、基布への吸着を防止して有効に殺菌消毒効果を発揮することができる殺菌消毒液と、この殺菌消毒液を基布に浸漬させた殺菌消毒剤が開示されている。この殺菌消毒液が、正電荷を帯びた殺菌消毒成分と、リシン、アルギニン、ヒスチジンおよびそれらの塩酸塩の中から選択される少なくとも１種以上のアミノ酸と、ノニオン系界面活性剤とを含有し、ｐＨ４〜９に調整されてなる殺菌消毒液である。
Biguanide fungicides and quaternary ammonium salt fungicides are used as the main components of various fungicides for disinfecting fingers, affected areas, medical devices, kitchens, bathrooms, textile materials, etc. Various improvements have been made depending on the application. For example, Patent Document 1 discloses a quaternary ammonium salt-based disinfectant or a biguanide-based disinfectant that reduces skin irritation during use and significantly improves the feel after use while maintaining excellent disinfectant power. Disinfectant compositions containing the same are disclosed. This disinfectant composition is composed of a polyalkylene glycol having a freezing point of 35 ° C. or higher or an alkylene glycol having a freezing point of 35 ° C. or higher, relative to a lower alcohol solution of quaternary ammonium salt based disinfectant or biguanide disinfectant. A derivative is blended in an amount of 0.01 to 2% by weight.
Further, Patent Document 2 discloses a sterilizing / disinfecting solution capable of effectively exerting a sterilizing effect by preventing adsorption to the base cloth, and a sterilizing / disinfecting agent in which the sterilizing / disinfecting liquid is immersed in the base cloth. ing. The disinfectant contains a positively-charged disinfectant component, at least one or more amino acids selected from lysine, arginine, histidine and their hydrochloride salts, and a nonionic surfactant. It is a sterilizing / disinfecting liquid adjusted to pH 4-9.
一方、なたねや大豆などの油糧種子から油脂を採取し、油粕が生じる油脂工場、油糧種子・油粕・油糧種子や油粕から製造される蛋白含有固形物を使用する食品工場や飼料工場では、作業員の靴底に付着した油粕や蛋白含有固形物が栄養源となりサルモネラが繁殖するため、工場への入退出時に靴底に付着したサルモネラを殺菌し、靴底を消毒する必要がある。しかしながら、このような用途に市販の消毒液を用いると、使用の度に消毒液中に油粕や蛋白含有固形物などの有機物が溜まり、これらの有機物が消毒液と反応して、消毒液の殺菌力が著しく低下するとの問題が生じている。さらに、これら有機物が油脂を含有するものであると油脂により消毒液が有機物へ浸透し難く、有機物中において十分な殺菌作用を発揮できない問題点も発生する。特に、食品工場の出入り口の靴底消毒マットに市販の塩化ベンザルコニウムの１％溶液がよく使用されているが、希釈して用いると十分な効果を得ることができないとの問題があった。なお、殺菌消毒剤に洗浄剤（界面活性剤）を含有させると、靴底消毒マットでよくゴミが落ち、また、工場内で靴底に付着した汚れも除去しやすいものの、消毒液中に油粕や蛋白含有固形物などの有機物が混入することによる消毒液の殺菌力の著しい低下の問題は解決しない。 On the other hand, in oil and fat factories where oils and fats are collected from oilseed such as rapeseed and soybeans, oil factories that produce oil lees, food factories and feed factories that use protein-containing solids produced from oil seeds, oil lees, oil seeds and oil lees Since salmonella is propagated as a source of nutrients and oil-containing solids attached to the shoe sole of workers, it is necessary to sterilize the salmonella attached to the shoe sole when entering and leaving the factory and disinfect the shoe sole. However, when a commercially available disinfectant is used for such applications, organic matter such as oil cake and protein-containing solids accumulates in the disinfectant each time it is used, and these organic matter reacts with the disinfectant to disinfect the disinfectant. There is a problem that the power is significantly reduced. Furthermore, if these organic substances contain fats and oils, it is difficult for the antiseptic solution to penetrate the organic substances due to the fats and oils, and there is also a problem that the sufficient bactericidal action can not be exhibited in the organic substances. In particular, a commercially available 1% solution of benzalkonium chloride is often used for shoe sole disinfection mats at the entrances and exits of food factories, but there is a problem that sufficient effects cannot be obtained when diluted. If a disinfectant contains a cleaning agent (surfactant), the shoe sole disinfecting mat will remove trash and the dirt on the shoe sole in the factory can be easily removed. It does not solve the problem of a marked decline in the bactericidal power of the disinfectant solution due to the contamination of organic matter such as protein solids and solid matter.
本発明は、消毒液中に油粕や蛋白含有固形物などの有機物が混入しても殺菌力の著しい低下を抑制できる、特に靴底に付着したサルモネラの殺菌消毒に有効な靴底消毒マット用殺菌消毒液組成物を提供することを目的とする。
本発明は、又、靴底に付着したサルモネラの効率的な殺菌消毒方法を提供することを目的とする。
The present invention is capable of suppressing a significant decrease in sterilizing power even when organic substances such as oil cake and protein-containing solids are mixed in the disinfectant, and is particularly effective for sterilization of salmonella attached to the shoe sole. An object is to provide a disinfectant composition.
Another object of the present invention is to provide an efficient method for sterilizing and disinfecting salmonella attached to soles.

The bactericidal antiseptic solution containing 100-fold diluted concentration <PHMB 0.09% (9% × 100-fold diluted) and DDAC 0.11% (11% × 100-fold diluted)> of Example 3 has an excellent bactericidal effect. It can be seen that a considerable effect is observed at a 50-fold dilution concentration.
実施例４
実施例３の消毒液を３０倍に水で希釈し、食品工場の出入口に設置してある靴底消毒マット（消毒マット：山崎産業株式会社製マット(#6)F-38-6：サイズ：600×900mm：材質PP 85%、ナイロン 15%：重量0.7 kg）に希釈した消毒液を約３リットル注入した。希釈した消毒液を毎日補充し、１週間ごとにサンプリングを行いサルモネラの検出の有無を確認した。サルモネラは、遺伝子増幅法(PCR)を用いた自動検出システムおよび飼料安全基準に準じた方法により判定した。
比較例５
比較例１の消毒液を希釈せずに、実施例４と同様の試験を行った。
実施例４と比較例５の結果をまとめて表４に示す。
Example 4
The shoe disinfection mat (disinfection mat: mat (# 6) F-38-6 manufactured by Yamazaki Sangyo Co., Ltd.) installed at the entrance of the food factory after diluting the disinfectant solution of Example 3 with water 30 times. About 3 liters of a disinfectant diluted in 600 × 900 mm: material PP 85%, nylon 15%: weight 0.7 kg) was injected. The diluted antiseptic solution was replenished daily and sampled weekly to confirm the presence or absence of salmonella detection. Salmonella was determined by an automatic detection system using gene amplification method (PCR) and a method according to the feed safety standard.
Comparative example 5
The same test as in Example 4 was performed without diluting the disinfectant solution of Comparative Example 1.
Table 4 summarizes the results of Example 4 and Comparative Example 5.
