| 1978 | British and Welsh cattle farmers were required to use Phosmet, Famphur or Fenthion (pour-on) or Derris to kill warble flies on every cow. Phosmet was most widely used. |
| 1980 | Change in UK rendering practice believed to allow infectious prions into the food chain |
| 1981 | Proportion of Meat & Bone Meal (MBM) produced using solvents drops from almost 50% to about 10% |
| 1982 | Use of Derris discontinued. Ivomec allowed but little used by dairy farmers |
| 1984 | Proportion of Meat & Bone Meal (MBM) produced by a continuous process reaches 75% |
| 1985 | The cow with the first documented case of BSE died, although some believe that cases occurred as early as the 1970s. A number of cows in the same herd had come down with symptoms that would now be called BSE. This cow was diagnosed with a toxic condition due to the condition of the kidneys. |
| 1985 | Dairy farmers limited to use of Phosmet for mandatory warble fly treatments due to changes in licensing for other previously allowed treatments. |
| 1986 | First verified case of Mad Cow (BSE) |
| 1986 November | BSE (Bovine Spongiform Encephalopathy) defined. Also known as Mad Cow Disease |
| 1988 July | Ban on ruminant (e.g. cow) protein in ruminant feed |
| 1990 September | Ban on specified bovine offal for use in animal nutrition |
| 1992 | Peak of UK Mad Cow epidemic (about 3500 new cases in peak months) |
| 1994 November | Ban on mammalian MBM (meat and bone meal) in ruminant feed |
| 1996 April | Mammalian MBM prohibited from all animal feed and fertilizer |
| 1996 June | Mammalian MBM and MBM-containing feed recalled |
| 2000 | UK Mad Cow cases down to negligible numbers |
